OpenJDK Build README

+ +
+ +

+ +

Introduction

+ +

This README file contains build instructions for the +OpenJDK. Building the source code for the OpenJDK +requires a certain degree of technical expertise.

+ +

!!!!!!!!!!!!!!! THIS IS A MAJOR RE-WRITE of this document. !!!!!!!!!!!!!

+ +

Some Headlines:

+ +
    +
  • The build is now a "configure && make" style build
    • +
  • Any GNU make 3.81 or newer should work, except on Windows where 4.0 or newer +is recommended.
    • +
  • The build should scale, i.e. more processors should cause the build to be +done in less wall-clock time
    • +
  • Nested or recursive make invocations have been significantly reduced, +as has the total fork/exec or spawning of sub processes during the build
    • +
  • Windows MKS usage is no longer supported
    • +
  • Windows Visual Studio vsvars*.bat and vcvars*.bat files are run +automatically
    • +
  • Ant is no longer used when building the OpenJDK
    • +
  • Use of ALT_* environment variables for configuring the build is no longer +supported
    • +
+ +
+ +

Use of Mercurial

+ +

The OpenJDK sources are maintained with the revision control system +Mercurial. If you are new to +Mercurial, please see the Beginner Guides or refer to the Mercurial Book. +The first few chapters of the book provide an excellent overview of Mercurial, +what it is and how it works.

+ +

For using Mercurial with the OpenJDK refer to the Developer Guide: Installing +and Configuring Mercurial section for more information.

+ +

+ +

Getting the Source

+ +

To get the entire set of OpenJDK Mercurial repositories use the script +get_source.sh located in the root repository:

  hg clone http://hg.openjdk.java.net/jdk9/jdk9 YourOpenJDK
+  cd YourOpenJDK
+  bash ./get_source.sh
+
+ +

Once you have all the repositories, keep in mind that each repository is its +own independent repository. You can also re-run ./get_source.sh anytime to +pull over all the latest changesets in all the repositories. This set of +nested repositories has been given the term "forest" and there are various +ways to apply the same hg command to each of the repositories. For +example, the script make/scripts/hgforest.sh can be used to repeat the +same hg command on every repository, e.g.

+ +
  cd YourOpenJDK
+  bash ./make/scripts/hgforest.sh status
+
+ +

+ +

Repositories

+ +

The set of repositories and what they contain:

+ +
    +
  • . (root) contains common configure and makefile logic
    • +
  • hotspot contains source code and make files for building the OpenJDK +Hotspot Virtual Machine
    • +
  • langtools contains source code for the OpenJDK javac and language tools
    • +
  • jdk contains source code and make files for building the OpenJDK runtime +libraries and misc files
    • +
  • jaxp contains source code for the OpenJDK JAXP functionality
    • +
  • jaxws contains source code for the OpenJDK JAX-WS functionality
    • +
  • corba contains source code for the OpenJDK Corba functionality
    • +
  • nashorn contains source code for the OpenJDK JavaScript implementation
    • +
+ +

Repository Source Guidelines

+ +

There are some very basic guidelines:

+ +
    +
  • Use of whitespace in source files (.java, .c, .h, .cpp, and .hpp files) is +restricted. No TABs, no trailing whitespace on lines, and files should not +terminate in more than one blank line.
    • +
  • Files with execute permissions should not be added to the source +repositories.
    • +
  • All generated files need to be kept isolated from the files maintained or +managed by the source control system. The standard area for generated files +is the top level build/ directory.
    • +
  • The default build process should be to build the product and nothing else, +in one form, e.g. a product (optimized), debug (non-optimized, -g plus +assert logic), or fastdebug (optimized, -g plus assert logic).
    • +
  • The .hgignore file in each repository must exist and should include +^build/, ^dist/ and optionally any nbproject/private directories. It +should NEVER include anything in the src/ or test/ or any managed +directory area of a repository.
    • +
  • Directory names and file names should never contain blanks or non-printing +characters.
    • +
  • Generated source or binary files should NEVER be added to the repository +(that includes javah output). There are some exceptions to this rule, in +particular with some of the generated configure scripts.
    • +
  • Files not needed for typical building or testing of the repository should +not be added to the repository.
    • +
+ +
+ +

+ +

Building

+ +

The very first step in building the OpenJDK is making sure the system itself +has everything it needs to do OpenJDK builds. Once a system is setup, it +generally doesn't need to be done again.

+ +

Building the OpenJDK is now done with running a configure script which will +try and find and verify you have everything you need, followed by running +make, e.g.

Use of Mercurial

-
- The OpenJDK sources are maintained with the revision control system - Mercurial. - If you are new to Mercurial, please see the - - Beginner Guides - or refer to the - Mercurial Book. - The first few chapters of the book provide an excellent overview of - Mercurial, what it is and how it works. -
- For using Mercurial with the OpenJDK refer to the - - Developer Guide: Installing and Configuring Mercurial - section for more information. - -

Getting the Source

-
- To get the entire set of OpenJDK Mercurial repositories - use the script get_source.sh located in the - root repository: -
- - hg clone http://hg.openjdk.java.net/jdk9/jdk9 - YourOpenJDK -
- cd YourOpenJDK -
- bash ./get_source.sh - -
- Once you have all the repositories, keep in mind that each - repository is its own independent repository. - You can also re-run ./get_source.sh anytime to - pull over all the latest changesets in all the repositories. - This set of nested repositories has been given the term - "forest" and there are various ways to apply the same - hg command to each of the repositories. - For example, the script make/scripts/hgforest.sh - can be used to repeat the same hg - command on every repository, e.g. -

Building

-
- The very first step in building the OpenJDK is making sure the - system itself has everything it needs to do OpenJDK builds. - Once a system is setup, it generally doesn't need to be done again. -
- Building the OpenJDK is now done with running a - configure - script which will try and find and verify you have everything - you need, followed by running - make, e.g. -
- - - bash ./configure
- make all - - -
- Where possible the configure script will attempt to located the - various components in the default locations or via component - specific variable settings. - When the normal defaults fail or components cannot be found, - additional configure options may be necessary to help configure - find the necessary tools for the build, or you may need to - re-visit the setup of your system due to missing software - packages. -
- NOTE: The configure script - file does not have - execute permissions and will need to be explicitly run with - bash, - see the source guidelines. - - -
-

System Setup

-
- Before even attempting to use a system to build the OpenJDK - there are some very basic system setups needed. - For all systems: -
    -
  • - Be sure the GNU make utility is version 3.81 (4.0 on - windows) or newer, e.g. run "make -version" -
    • -
  • - Install a - Bootstrap JDK. - All OpenJDK builds require access to a previously released - JDK called the bootstrap JDK or boot JDK. - The general rule is that the bootstrap JDK - must be an instance of the previous major - release of the JDK. In addition, there may be - a requirement to use a release at or beyond a - particular update level. -
     
    - - Building JDK 9 requires JDK 8. JDK 9 - developers should not use JDK 9 as the boot - JDK, to ensure that JDK 9 dependencies are - not introduced into the parts of the system - that are built with JDK 8. - -
     
    - The JDK 8 binaries can be downloaded from Oracle's - JDK 8 download site. - For build performance reasons it - is very important that this bootstrap JDK be made available - on the local disk of the machine doing the build. - You should add its bin directory - to the PATH environment variable. - If configure has any issues finding this JDK, you may - need to use the configure option - --with-boot-jdk. -
    • -
  • - Ensure that GNU make, the Bootstrap JDK, - and the compilers are all - in your PATH environment variable -
    • -
- And for specific systems: - - - - - - - - - - - - - - - - - -
LinuxSolarisWindowsMac OS X
- Install all the software development - packages needed including - alsa, - freetype, - cups, and - xrender. -
- See - specific system packages. - 		- Install all the software development - packages needed including - Studio Compilers, - freetype, - cups, and - xrender. -
- See - specific system packages. - 		- - - Install - XCode 4.5.2 - and also install the "Command line tools" found under the - preferences pane "Downloads" -
- -

Linux

-
- With Linux, try and favor the system packages over - building your own - or getting packages from other areas. - Most Linux builds should be possible with the system's - available packages. -
- Note that some Linux systems have a habit of pre-populating - your environment variables for you, for example JAVA_HOME - might get pre-defined for you to refer to the JDK installed on - your Linux system. - You will need to unset JAVA_HOME. - It's a good idea to run env and verify the - environment variables you are getting from the default system - settings make sense for building the OpenJDK. - -
- -

Windows

-
- -
Windows Unix Toolkit
-
- Building on Windows requires a Unix-like environment, notably a - Unix-like shell. - There are several such environments available of which - Cygwin and - MinGW/MSYS are - currently supported for - the OpenJDK build. One of the differences of these - systems from standard Windows tools is the way - they handle Windows path names, particularly path names which contain - spaces, backslashes as path separators and possibly drive letters. - Depending - on the use case and the specifics of each environment these path - problems can - be solved by a combination of quoting whole paths, translating - backslashes to - forward slashes, escaping backslashes with additional backslashes and - translating the path names to their - - "8.3" version. - -
CYGWIN
-
- CYGWIN is an open source, Linux-like environment which tries to emulate - a complete POSIX layer on Windows. It tries to be smart about path names - and can usually handle all kinds of paths if they are correctly quoted - or escaped although internally it maps drive letters <drive>: - to a virtual directory /cygdrive/<drive>. -

- You can always use the cygpath utility to map pathnames with spaces - or the backslash character into the C:/ style of pathname - (called 'mixed'), e.g. cygpath -s -m "path". -

-

- Note that the use of CYGWIN creates a unique problem with regards to - setting PATH. Normally on Windows - the PATH variable contains directories - separated with the ";" character (Solaris and Linux use ":"). - With CYGWIN, it uses ":", but that means that paths like "C:/path" - cannot be placed in the CYGWIN version of PATH and - instead CYGWIN uses something like /cygdrive/c/path - which CYGWIN understands, but only CYGWIN understands. -

-

- The OpenJDK build requires CYGWIN version 1.7.16 or newer. - Information about CYGWIN can - be obtained from the CYGWIN website at - www.cygwin.com. -

-

- By default CYGWIN doesn't install all the tools required for building - the OpenJDK. - Along with the default installation, you need to install - the following tools. -

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Binary NameCategoryPackageDescription
ar.exeDevelbinutils - The GNU assembler, linker and binary utilities -
make.exeDevelmake - The GNU version of the 'make' utility built for CYGWIN -
m4.exeInterpretersm4 - GNU implementation of the traditional Unix macro - processor -
cpio.exeUtilscpio - A program to manage archives of files -

zip.exeArchivezip - Package and compress (archive) files -
unzip.exeArchiveunzip - Extract compressed files in a ZIP archive -
free.exeSystemprocps - Display amount of free and used memory in the system -
-
- Note that the CYGWIN software can conflict with other non-CYGWIN - software on your Windows system. - CYGWIN provides a - FAQ for - known issues and problems, of particular interest is the - section on - - BLODA (applications that interfere with CYGWIN). -
- -
MinGW/MSYS
-
- MinGW ("Minimalist GNU for Windows") is a collection of free Windows - specific header files and import libraries combined with GNU toolsets that - allow one to produce native Windows programs that do not rely on any - 3rd-party C runtime DLLs. MSYS is a supplement to MinGW which allows building - applications and programs which rely on traditional UNIX tools to - be present. Among others this includes tools like bash - and make. - See MinGW/MSYS - for more information. -

- Like Cygwin, MinGW/MSYS can handle different types of path formats. They - are internally converted to paths with forward slashes and drive letters - <drive>: replaced by a virtual - directory /<drive>. Additionally, MSYS automatically - detects binaries compiled for the MSYS environment and feeds them with the - internal, Unix-style path names. If native Windows applications are called - from within MSYS programs their path arguments are automatically converted - back to Windows style path names with drive letters and backslashes as - path separators. This may cause problems for Windows applications which - use forward slashes as parameter separator (e.g. cl /nologo /I) - because MSYS may wrongly - replace such parameters by drive letters. -

-

- In addition to the tools which will be installed - by default, you have - to manually install the - msys-zip and - msys-unzip packages. - This can be easily done with the MinGW command line installer: -

- mingw-get.exe install msys-zip -
- mingw-get.exe install msys-unzip -
-
- -
- -
Visual Studio 2013 Compilers
-
-

- The 32-bit and 64-bit OpenJDK Windows build requires - Microsoft Visual Studio C++ 2013 (VS2013) Professional - Edition or Express compiler. - The compiler and other tools are expected to reside - in the location defined by the variable - VS120COMNTOOLS which - is set by the Microsoft Visual Studio installer. -

-

- Only the C++ part of VS2013 is needed. - Try to let the installation go to the default - install directory. - Always reboot your system after installing VS2013. - The system environment variable VS120COMNTOOLS - should be - set in your environment. -

-

- Make sure that TMP and TEMP are also set - in the environment - and refer to Windows paths that exist, - like C:\temp, - not /tmp, not /cygdrive/c/temp, - and not C:/temp. - C:\temp is just an example, - it is assumed that this area is - private to the user, so by default - after installs you should - see a unique user path in these variables. -

-
- - -
- -

Mac OS X

-
- Make sure you get the right XCode version. -
- -
- - -
-

Configure

-
- The basic invocation of the configure script - looks like: -
- bash ./configure [options] -
- This will create an output directory containing the - "configuration" and setup an area for the build result. - This directory typically looks like: -
- build/linux-x64-normal-server-release -
- configure will try to figure out what system you are running on - and where all necessary build components are. - If you have all prerequisites for building installed, - it should find everything. - If it fails to detect any component automatically, - it will exit and inform you about the problem. - When this happens, read more below in - the configure options. -

- Some examples: -

- - - - - - - - - - - - - - - - - -
DescriptionConfigure Command Line
Windows 32bit build with freetype specified - bash ./configure --with-freetype=/cygdrive/c/freetype-i586 --with-target-bits=32 -
Debug 64bit Build - bash ./configure --enable-debug --with-target-bits=64 -
- - -

Configure Options

-
- Complete details on all the OpenJDK configure options can - be seen with: -
- bash ./configure --help=short -
- Use -help to see all the configure options - available. - - You can generate any number of different configurations, - e.g. debug, release, 32, 64, etc. - - Some of the more commonly used configure options are: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
OpenJDK Configure OptionDescription
--enable-debug - set the debug level to fastdebug (this is a shorthand for - --with-debug-level=fastdebug) -
--with-alsa=path - select the location of the - Advanced Linux Sound Architecture (ALSA) -
- Version 0.9.1 or newer of the ALSA files are - required for building the OpenJDK on Linux. - These Linux files are usually available from an "alsa" - of "libasound" - development package, - and it's highly recommended that you try and use - the package provided by the particular version of Linux that - you are using. -
--with-boot-jdk=path - select the Bootstrap JDK -
--with-boot-jdk-jvmargs="args" - provide the JVM options to be used to run the - Bootstrap JDK -
--with-cacerts=path - select the path to the cacerts file. -
- See - http://en.wikipedia.org/wiki/Certificate_Authority - for a better understanding of the Certificate Authority (CA). - A certificates file named "cacerts" - represents a system-wide keystore with CA certificates. - In JDK and JRE - binary bundles, the "cacerts" file contains root CA certificates from - several public CAs (e.g., VeriSign, Thawte, and Baltimore). - The source contain a cacerts file - without CA root certificates. - Formal JDK builders will need to secure - permission from each public CA and include the certificates into their - own custom cacerts file. - Failure to provide a populated cacerts file - will result in verification errors of a certificate chain during runtime. - By default an empty cacerts file is provided and that should be - fine for most JDK developers. -
--with-cups=path - select the CUPS install location -
- The - Common UNIX Printing System (CUPS) Headers - are required for building the - OpenJDK on Solaris and Linux. - The Solaris header files can be obtained by installing - the package SFWcups from the Solaris Software - Companion CD/DVD, these often will be installed into the - directory /opt/sfw/cups. -
- The CUPS header files can always be downloaded from - www.cups.org. -
--with-cups-include=path - select the CUPS include directory location -
--with-debug-level=level - select the debug information level of release, - fastdebug, or slowdebug -
--with-dev-kit=path - select location of the compiler install or - developer install location -
--with-freetype=path - select the freetype files to use. -
- Expecting the - freetype libraries under - lib/ and the - headers under include/. -
- Version 2.3 or newer of FreeType is required. - On Unix systems required files can be available as part of your - distribution (while you still may need to upgrade them). - Note that you need development version of package that - includes both the FreeType library and header files. -
- You can always download latest FreeType version from the - FreeType website. -
- Building the freetype 2 libraries from scratch is also possible, - however on Windows refer to the - - Windows FreeType DLL build instructions. -
- Note that by default FreeType is built with byte code hinting - support disabled due to licensing restrictions. - In this case, text appearance and metrics are expected to - differ from Sun's official JDK build. - See - - the SourceForge FreeType2 Home Page - - for more information. -
--with-import-hotspot=path - select the location to find hotspot - binaries from a previous build to avoid building - hotspot -
--with-target-bits=arg - select 32 or 64 bit build -
--with-jvm-variants=variants - select the JVM variants to build from, comma - separated list that can include: - server, client, kernel, zero and zeroshark -
--with-memory-size=size - select the RAM size that GNU make will think - this system has -
--with-msvcr-dll=path - select the msvcr100.dll - file to include in the - Windows builds (C/C++ runtime library for - Visual Studio). -
- This is usually picked up automatically - from the redist - directories of Visual Studio 2013. -
--with-num-cores=cores - select the number of cores to use (processor - count or CPU count) -
--with-x=path - select the location of the X11 and xrender files. -
- The - XRender Extension Headers - are required for building the - OpenJDK on Solaris and Linux. -
- The Linux header files are usually available from a "Xrender" - development package, it's recommended that you try and use - the package provided by the particular distribution of Linux that - you are using. -
- The Solaris XRender header files is - included with the other X11 header files - in the package SFWxwinc - on new enough versions of - Solaris and will be installed in - /usr/X11/include/X11/extensions/Xrender.h or - /usr/openwin/share/include/X11/extensions/Xrender.h -

Make

-
- The basic invocation of the make utility - looks like: -
- make all -
- This will start the build to the output directory containing the - "configuration" that was created by the configure - script. Run make help for more information on - the available targets. -
- There are some of the make targets that - are of general interest: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Make TargetDescription
emptybuild everything but no images
allbuild everything including images
all-confbuild all configurations
imagescreate complete j2sdk and j2re images
installinstall the generated images locally, - typically in /usr/local
cleanremove all files generated by make, - but not those generated by configure
dist-cleanremove all files generated by both - and configure (basically killing the configuration)
helpgive some help on using make, - including some interesting make targets
-
-
- - -
-

Testing

-
- When the build is completed, you should see the generated - binaries and associated files in the j2sdk-image - directory in the output directory. - In particular, the - build/*/images/j2sdk-image/bin - directory should contain executables for the - OpenJDK tools and utilities for that configuration. - The testing tool jtreg will be needed - and can be found at: - - the jtreg site. - The provided regression tests in the repositories - can be run with the command: -
- cd test && make PRODUCT_HOME=`pwd`/../build/*/images/j2sdk-image all -

FAQ

-
- -

- Q: The generated-configure.sh file looks horrible! - How are you going to edit it? -
- A: The generated-configure.sh file is generated (think - "compiled") by the autoconf tools. The source code is - in configure.ac and various .m4 files in common/autoconf, - which are much more readable. -

- -

- Q: - Why is the generated-configure.sh file checked in, - if it is generated? -
- A: - If it was not generated, every user would need to have the autoconf - tools installed, and re-generate the configure file - as the first step. - Our goal is to minimize the work needed to be done by the user - to start building OpenJDK, and to minimize - the number of external dependencies required. -

- -

- Q: - Do you require a specific version of autoconf for regenerating - generated-configure.sh? -
- A: - Yes, version 2.69 is required and should be easy - enough to aquire on all supported operating - systems. The reason for this is to avoid - large spurious changes in generated-configure.sh. -

- -

- Q: - How do you regenerate generated-configure.sh - after making changes to the input files? -
- A: - Regnerating generated-configure.sh - should always be done using the - script common/autoconf/autogen.sh to - ensure that the correct files get updated. This - script should also be run after mercurial tries to - merge generated-configure.sh as a - merge of the generated file is not guaranteed to - be correct. -

- Q: - What are the files in common/makefiles/support/* for? - They look like gibberish. -
- A: - They are a somewhat ugly hack to compensate for command line length - limitations on certain platforms (Windows, Solaris). - Due to a combination of limitations in make and the shell, - command lines containing too many files will not work properly. - These - helper files are part of an elaborate hack that will compress the - command line in the makefile and then uncompress it safely. - We're - not proud of it, but it does fix the problem. - If you have any better suggestions, we're all ears! :-) -

- -

- Q: - I want to see the output of the commands that make runs, - like in the old build. How do I do that? -
- A: - You specify the LOG variable to make. There are - several log levels: -

-
-
    -
  • - warn — Default and very quiet. -
    • -
  • - info — Shows more progress information - than warn. -
    • -
  • - debug — Echos all command lines and - prints all macro calls for compilation definitions. -
    • -
  • - trace — Echos all $(shell) command - lines as well. -
    • -
-
- -

- Q: - When do I have to re-run configure? -
- A: - Normally you will run configure only once for creating a - configuration. - You need to re-run configuration only if you want to change any - configuration options, - or if you pull down changes to the configure script. -

- -

- Q: - I have added a new source file. Do I need to modify the makefiles? -
- A: - Normally, no. If you want to create e.g. a new native - library, - you will need to modify the makefiles. But for normal file - additions or removals, no changes are needed. There are certan - exceptions for some native libraries where the source files are spread - over many directories which also contain sources for other - libraries. In these cases it was simply easier to create include lists - rather than excludes. -

- -

- Q: - When I run configure --help, I see many strange options, - like --dvidir. What is this? -
- A: - Configure provides a slew of options by default, to all projects - that use autoconf. Most of them are not used in OpenJDK, - so you can safely ignore them. To list only OpenJDK specific features, - use configure --help=short instead. -

- -

- Q: - configure provides OpenJDK-specific features such as - --with-builddeps-server that are not - described in this document. What about those? -
- A: - Try them out if you like! But be aware that most of these are - experimental features. - Many of them don't do anything at all at the moment; the option - is just a placeholder. Others depend on - pieces of code or infrastructure that is currently - not ready for prime time. -

- -

- Q: - How will you make sure you don't break anything? -
- A: - We have a script that compares the result of the new build system - with the result of the old. For most part, we aim for (and achieve) - byte-by-byte identical output. There are however technical issues - with e.g. native binaries, which might differ in a byte-by-byte - comparison, even - when building twice with the old build system. - For these, we compare relevant aspects - (e.g. the symbol table and file size). - Note that we still don't have 100% - equivalence, but we're close. -

- -

- Q: - I noticed this thing X in the build that looks very broken by design. - Why don't you fix it? -
- A: - Our goal is to produce a build output that is as close as - technically possible to the old build output. - If things were weird in the old build, - they will be weird in the new build. - Often, things were weird before due to obscurity, - but in the new build system the weird stuff comes up to the surface. - The plan is to attack these things at a later stage, - after the new build system is established. -

- -

- Q: - The code in the new build system is not that well-structured. - Will you fix this? -
- A: - Yes! The new build system has grown bit by bit as we converted - the old system. When all of the old build system is converted, - we can take a step back and clean up the structure of the new build - system. Some of this we plan to do before replacing the old build - system and some will need to wait until after. -

- -

- Q: - Is anything able to use the results of the new build's default make target? -
- A: - Yes, this is the minimal (or roughly minimal) - set of compiled output needed for a developer to actually - execute the newly built JDK. The idea is that in an incremental - development fashion, when doing a normal make, - you should only spend time recompiling what's changed - (making it purely incremental) and only do the work that's - needed to actually run and test your code. - The packaging stuff that is part of the images - target is not needed for a normal developer who wants to - test his new code. Even if it's quite fast, it's still unnecessary. - We're targeting sub-second incremental rebuilds! ;-) - (Or, well, at least single-digit seconds...) -

- -

- Q: - I usually set a specific environment variable when building, - but I can't find the equivalent in the new build. - What should I do? -
- A: - It might very well be that we have neglected to add support for - an option that was actually used from outside the build system. - Email us and we will add support for it! -

Build Performance Tips

-
- -

Building OpenJDK requires a lot of horsepower. - Some of the build tools can be adjusted to utilize more or less - of resources such as - parallel threads and memory. - The configure script analyzes your system and selects reasonable - values for such options based on your hardware. - If you encounter resource problems, such as out of memory conditions, - you can modify the detected values with:

- -
    -
  • - --with-num-cores - — - number of cores in the build system, - e.g. --with-num-cores=8 -
    • -
  • - --with-memory-size - — memory (in MB) available in the build system, - e.g. --with-memory-size=1024 -
    • -
- -

It might also be necessary to specify the JVM arguments passed - to the Bootstrap JDK, using e.g. - --with-boot-jdk-jvmargs="-Xmx8G -enableassertions". - Doing this will override the default JVM arguments - passed to the Bootstrap JDK.

- - -

One of the top goals of the new build system is to improve the - build performance and decrease the time needed to build. This will - soon also apply to the java compilation when the Smart Javac wrapper - is fully supported.

- -

At the end of a successful execution of configure, - you will get a performance summary, - indicating how well the build will perform. Here you will - also get performance hints. - If you want to build fast, pay attention to those!

- -

Building with ccache

- -

The OpenJDK build supports building with ccache - when using gcc or clang. Using ccache can - radically speed up compilation of native code if - you often rebuild the same sources. Your milage - may vary however so we recommend evaluating it for - yourself. To enable it, make sure it's on the path - and configure with --enable-ccache.

- -

Building on local disk

- -

If you are using network shares, e.g. via NFS, for your source code, - make sure the build directory is situated on local disk. - The performance - penalty is extremely high for building on a network share, - close to unusable.

- -

Building only one JVM

- -

The old build builds multiple JVMs on 32-bit systems (client and - server; and on Windows kernel as well). In the new build we have - changed this default to only build server when it's available. This - improves build times for those not interested in multiple JVMs. To - mimic the old behavior on platforms that support it, - use --with-jvm-variants=client,server.

- -

Selecting the number of cores to build on

- -

By default, configure will analyze your machine and run the make - process in parallel with as many threads as you have cores. This - behavior can be overridden, either "permanently" (on a configure - basis) using --with-num-cores=N or for a single build - only (on a make basis), using make JOBS=N.

- -

If you want to make a slower build just this time, to save some CPU - power for other processes, you can run - e.g. make JOBS=2. This will force the makefiles - to only run 2 parallel processes, or even make JOBS=1 - which will disable parallelism.

- -

If you want to have it the other way round, namely having slow - builds default and override with fast if you're - impatient, you should call configure with - --with-num-cores=2, making 2 the default. - If you want to run with more - cores, run make JOBS=8

- -
- -

Troubleshooting

-
- -

Solving build problems

- -
- If the build fails (and it's not due to a compilation error in - a source file you've changed), the first thing you should do - is to re-run the build with more verbosity. - Do this by adding LOG=debug to your make command line. -
- The build log (with both stdout and stderr intermingled, - basically the same as you see on your console) can be found as - build.log in your build directory. -
- You can ask for help on build problems with the new build system - on either the - - build-dev - or the - - build-infra-dev - mailing lists. Please include the relevant parts - of the build log. -
- A build can fail for any number of reasons. - Most failures - are a result of trying to build in an environment in which all the - pre-build requirements have not been met. - The first step in - troubleshooting a build failure is to recheck that you have satisfied - all the pre-build requirements for your platform. - Scanning the configure log is a good first step, making - sure that what it found makes sense for your system. - Look for strange error messages or any difficulties that - configure had in finding things. -
- Some of the more common problems with builds are briefly - described - below, with suggestions for remedies. -
    -
  • - Corrupted Bundles on Windows: -
    - Some virus scanning software has been known to - corrupt the - downloading of zip bundles. - It may be necessary to disable the 'on access' or - 'real time' - virus scanning features to prevent this corruption. - This type of "real time" virus scanning can also - slow down the - build process significantly. - Temporarily disabling the feature, or excluding the build - output directory may be necessary to get correct and - faster builds. -
    -
    • -
  • - Slow Builds: -
    - If your build machine seems to be overloaded from too many - simultaneous C++ compiles, try setting the - JOBS=1 on the make command line. - Then try increasing the count slowly to an acceptable - level for your system. Also: -
    - Creating the javadocs can be very slow, - if you are running - javadoc, consider skipping that step. -
    - Faster CPUs, more RAM, and a faster DISK usually helps. - The VM build tends to be CPU intensive - (many C++ compiles), - and the rest of the JDK will often be disk intensive. -
    - Faster compiles are possible using a tool called - ccache. -
    -
    -
    • -
  • - File time issues: -
    - If you see warnings that refer to file time stamps, e.g. -
    - Warning message: - File `xxx' has modification time in - the future. -
    - Warning message: Clock skew detected. - Your build may - be incomplete. -
    - These warnings can occur when the clock on the build - machine is out of - sync with the timestamps on the source files. - Other errors, apparently - unrelated but in fact caused by the clock skew, - can occur along with - the clock skew warnings. - These secondary errors may tend to obscure the - fact that the true root cause of the problem - is an out-of-sync clock. -

    - If you see these warnings, reset the clock on the - build - machine, run "gmake clobber" - or delete the directory - containing the build output, and restart the - build from the beginning. -

    -
    • -
  • - Error message: - Trouble writing out table to disk -
    - Increase the amount of swap space on your build machine. - This could be caused by overloading the system and - it may be necessary to use: -
    - make JOBS=1 -
    - to reduce the load on the system. -
    -
    • -
  • - Error Message: - libstdc++ not found: -
    - This is caused by a missing libstdc++.a library. - This is installed as part of a specific package - (e.g. libstdc++.so.devel.386). - By default some 64-bit Linux versions (e.g. Fedora) - only install the 64-bit version of the libstdc++ package. - Various parts of the JDK build require a static - link of the C++ runtime libraries to allow for maximum - portability of the built images. -
    -
    • -
  • - Linux Error Message: - cannot restore segment prot after reloc -
    - This is probably an issue with SELinux (See - - http://en.wikipedia.org/wiki/SELinux). - Parts of the VM is built without the -fPIC for - performance reasons. -

    - To completely disable SELinux: -

      -
    1. $ su root
      2. -
    2. # system-config-securitylevel
      3. -
    3. In the window that appears, select the SELinux tab
      4. -
    4. Disable SELinux
      5. -
    -

    - Alternatively, instead of completely disabling it you could - disable just this one check. -

      -
    1. Select System->Administration->SELinux Management
      2. -
    2. In the SELinux Management Tool which appears, - select "Boolean" from the menu on the left
      3. -
    3. Expand the "Memory Protection" group
      4. -
    4. Check the first item, labeled - "Allow all unconfined executables to use - libraries requiring text relocation ..."
      5. -

Appendix B: GNU make

-
- - The Makefiles in the OpenJDK are only valid when used with the - GNU version of the utility command make - (usually called gmake on Solaris). - A few notes about using GNU make: -
    -
  • - You need GNU make version 3.81 or newer. On Windows 4.0 or - newer is recommended. - If the GNU make utility on your systems is not of a suitable - version see "Building GNU make". -
    • -
  • - Place the location of the GNU make binary in the - PATH. -
    • -
  • - Solaris: - Do NOT use /usr/bin/make on Solaris. - If your Solaris system has the software - from the Solaris Developer Companion CD installed, - you should try and use gmake - which will be located in either the - /usr/bin, /opt/sfw/bin or - /usr/sfw/bin directory. -
    • -
  • - Windows: - Make sure you start your build inside a bash shell. -
    • -
  • - Mac OS X: - The XCode "command line tools" must be installed on your Mac. -
    • -
-

- Information on GNU make, and access to ftp download sites, are - available on the - - GNU make web site - . - The latest source to GNU make is available at - - ftp.gnu.org/pub/gnu/make/. -

- -

Building GNU make

-
- First step is to get the GNU make 3.81 or newer source from - - ftp.gnu.org/pub/gnu/make/. - Building is a little different depending on the OS but is - basically done with: -
- bash ./configure -
- make -

Appendix C: Build Environments

-
- -

Minimum Build Environments

-
- This file often describes specific requirements for what we - call the - "minimum build environments" (MBE) for this - specific release of the JDK. - What is listed below is what the Oracle Release - Engineering Team will use to build the Oracle JDK product. - Building with the MBE will hopefully generate the most compatible - bits that install on, and run correctly on, the most variations - of the same base OS and hardware architecture. - In some cases, these represent what is often called the - least common denominator, but each Operating System has different - aspects to it. -

- In all cases, the Bootstrap JDK version minimum is critical, - we cannot guarantee builds will work with older Bootstrap JDK's. - Also in all cases, more RAM and more processors is better, - the minimums listed below are simply recommendations. -

- With Solaris and Mac OS X, the version listed below is the - oldest release we can guarantee builds and works, and the - specific version of the compilers used could be critical. -

- With Windows the critical aspect is the Visual Studio compiler - used, which due to it's runtime, generally dictates what Windows - systems can do the builds and where the resulting bits can - be used.
- NOTE: We expect a change here off these older Windows OS releases - and to a 'less older' one, probably Windows 2008R2 X64. -

- With Linux, it was just a matter of picking a - stable distribution that is a good representative for Linux - in general.
- NOTE: We expect a change here from Fedora 9 to something else, - but it has not been completely determined yet, possibly - Ubuntu 12.04 X64, unbiased community feedback would be welcome on - what a good choice would be here. -

- It is understood that most developers will NOT be using these - specific versions, and in fact creating these specific versions - may be difficult due to the age of some of this software. - It is expected that developers are more often using the more - recent releases and distributions of these operating systems. -

- Compilation problems with newer or different C/C++ compilers is a - common problem. - Similarly, compilation problems related to changes to the - /usr/include or system header files is also a - common problem with older, newer, or unreleased OS versions. - Please report these types of problems as bugs so that they - can be dealt with accordingly. -

System Setup

+ +

Before even attempting to use a system to build the OpenJDK there are some very +basic system setups needed. For all systems:

+ +
    +

  • Be sure the GNU make utility is version 3.81 (4.0 on windows) or newer, e.g. +run "make -version"

    + +

    • +

  • Install a Bootstrap JDK. All OpenJDK builds require access to a previously +released JDK called the bootstrap JDK or boot JDK. The general rule is +that the bootstrap JDK must be an instance of the previous major release of +the JDK. In addition, there may be a requirement to use a release at or +beyond a particular update level.

    + +

    Building JDK 9 requires JDK 8. JDK 9 developers should not use JDK 9 as +the boot JDK, to ensure that JDK 9 dependencies are not introduced into the +parts of the system that are built with JDK 8.

    + +

    The JDK 8 binaries can be downloaded from Oracle's JDK 8 download +site. +For build performance reasons it is very important that this bootstrap JDK +be made available on the local disk of the machine doing the build. You +should add its bin directory to the PATH environment variable. If +configure has any issues finding this JDK, you may need to use the +configure option --with-boot-jdk.

    • +

  • Ensure that GNU make, the Bootstrap JDK, and the compilers are all in your +PATH environment variable.

    • +
+ +

And for specific systems:

+ + + +

+ +

Linux

+ +

With Linux, try and favor the system packages over building your own or getting +packages from other areas. Most Linux builds should be possible with the +system's available packages.

+ +

Note that some Linux systems have a habit of pre-populating your environment +variables for you, for example JAVA_HOME might get pre-defined for you to +refer to the JDK installed on your Linux system. You will need to unset +JAVA_HOME. It's a good idea to run env and verify the environment variables +you are getting from the default system settings make sense for building the +OpenJDK.

+ +

+ +

Solaris

+ +

+ +
Studio Compilers
+ +

At a minimum, the Studio 12 Update 1 Compilers (containing +version 5.10 of the C and C++ compilers) is required, including specific +patches.

+ +

+ +

Windows

+ +
Windows Unix Toolkit
+ +

Building on Windows requires a Unix-like environment, notably a Unix-like +shell. There are several such environments available of which +Cygwin and +MinGW/MSYS are currently supported for the +OpenJDK build. One of the differences of these systems from standard Windows +tools is the way they handle Windows path names, particularly path names which +contain spaces, backslashes as path separators and possibly drive letters. +Depending on the use case and the specifics of each environment these path +problems can be solved by a combination of quoting whole paths, translating +backslashes to forward slashes, escaping backslashes with additional +backslashes and translating the path names to their "8.3" +version.

+ +

+ +
CYGWIN
+ +

CYGWIN is an open source, Linux-like environment which tries to emulate a +complete POSIX layer on Windows. It tries to be smart about path names and can +usually handle all kinds of paths if they are correctly quoted or escaped +although internally it maps drive letters <drive>: to a virtual directory +/cygdrive/<drive>.

+ +

You can always use the cygpath utility to map pathnames with spaces or the +backslash character into the C:/ style of pathname (called 'mixed'), e.g. +cygpath -s -m "<path>".

+ +

Note that the use of CYGWIN creates a unique problem with regards to setting +PATH. Normally on Windows the PATH variable contains directories +separated with the ";" character (Solaris and Linux use ":"). With CYGWIN, it +uses ":", but that means that paths like "C:/path" cannot be placed in the +CYGWIN version of PATH and instead CYGWIN uses something like +/cygdrive/c/path which CYGWIN understands, but only CYGWIN understands.

+ +

The OpenJDK build requires CYGWIN version 1.7.16 or newer. Information about +CYGWIN can be obtained from the CYGWIN website at +www.cygwin.com.

+ +

By default CYGWIN doesn't install all the tools required for building the +OpenJDK. Along with the default installation, you need to install the following +tools.

+ +
+

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

Note that the CYGWIN software can conflict with other non-CYGWIN software on +your Windows system. CYGWIN provides a FAQ for known issues and problems, of particular interest is the +section on BLODA (applications that interfere with +CYGWIN).

+ +

+ +
MinGW/MSYS
+ +

MinGW ("Minimalist GNU for Windows") is a collection of free Windows specific +header files and import libraries combined with GNU toolsets that allow one to +produce native Windows programs that do not rely on any 3rd-party C runtime +DLLs. MSYS is a supplement to MinGW which allows building applications and +programs which rely on traditional UNIX tools to be present. Among others this +includes tools like bash and make. See MinGW/MSYS for more information.

+ +

Like Cygwin, MinGW/MSYS can handle different types of path formats. They are +internally converted to paths with forward slashes and drive letters +<drive>: replaced by a virtual directory /<drive>. Additionally, MSYS +automatically detects binaries compiled for the MSYS environment and feeds them +with the internal, Unix-style path names. If native Windows applications are +called from within MSYS programs their path arguments are automatically +converted back to Windows style path names with drive letters and backslashes +as path separators. This may cause problems for Windows applications which use +forward slashes as parameter separator (e.g. cl /nologo /I) because MSYS may +wrongly replace such parameters by drive letters.

+ +

In addition to the tools which will be installed by default, you have to +manually install the msys-zip and msys-unzip packages. This can be easily +done with the MinGW command line installer:

+ +
  mingw-get.exe install msys-zip
+  mingw-get.exe install msys-unzip
+
+ +

+ +
Visual Studio 2013 Compilers
+ +

The 32-bit and 64-bit OpenJDK Windows build requires Microsoft Visual Studio +C++ 2013 (VS2013) Professional Edition or Express compiler. The compiler and +other tools are expected to reside in the location defined by the variable +VS120COMNTOOLS which is set by the Microsoft Visual Studio installer.

+ +

Only the C++ part of VS2013 is needed. Try to let the installation go to the +default install directory. Always reboot your system after installing VS2013. +The system environment variable VS120COMNTOOLS should be set in your +environment.

+ +

Make sure that TMP and TEMP are also set in the environment and refer to +Windows paths that exist, like C:\temp, not /tmp, not /cygdrive/c/temp, +and not C:/temp. C:\temp is just an example, it is assumed that this area +is private to the user, so by default after installs you should see a unique +user path in these variables.

+ +

+ +

Mac OS X

+ +

Make sure you get the right XCode version.

+ +
+ +

+ +

Configure

+ +

The basic invocation of the configure script looks like:

+ +
+

bash ./configure [options]

+
+ +

This will create an output directory containing the "configuration" and setup +an area for the build result. This directory typically looks like:

+ +
+

build/linux-x64-normal-server-release

+
+ +

configure will try to figure out what system you are running on and where all +necessary build components are. If you have all prerequisites for building +installed, it should find everything. If it fails to detect any component +automatically, it will exit and inform you about the problem. When this +happens, read more below in the configure options.

+ +

Some examples:

+ +
+

Windows 32bit build with freetype specified:
+ bash ./configure --with-freetype=/cygdrive/c/freetype-i586 --with-target- +bits=32

+ +

Debug 64bit Build:
+ bash ./configure --enable-debug --with-target-bits=64

+
+ +

+ +

Configure Options

+ +

Complete details on all the OpenJDK configure options can be seen with:

+ +
+

bash ./configure --help=short

+
+ +

Use -help to see all the configure options available. You can generate any +number of different configurations, e.g. debug, release, 32, 64, etc.

+ +

Some of the more commonly used configure options are:

+ +
+

--enable-debug
+ set the debug level to fastdebug (this is a shorthand for --with-debug- + level=fastdebug)

+
+ +

+ +
+

--with-alsa=path
+ select the location of the Advanced Linux Sound Architecture (ALSA)

+ +

Version 0.9.1 or newer of the ALSA files are required for building the + OpenJDK on Linux. These Linux files are usually available from an "alsa" of + "libasound" development package, and it's highly recommended that you try + and use the package provided by the particular version of Linux that you are + using.

+ +

--with-boot-jdk=path
+ select the Bootstrap JDK

+ +

--with-boot-jdk-jvmargs="args"
+ provide the JVM options to be used to run the Bootstrap JDK

+ +

--with-cacerts=path
+ select the path to the cacerts file.

+ +

See Certificate Authority on Wikipedia for a better understanding of the Certificate + Authority (CA). A certificates file named "cacerts" represents a system-wide + keystore with CA certificates. In JDK and JRE binary bundles, the "cacerts" + file contains root CA certificates from several public CAs (e.g., VeriSign, + Thawte, and Baltimore). The source contain a cacerts file without CA root + certificates. Formal JDK builders will need to secure permission from each + public CA and include the certificates into their own custom cacerts file. + Failure to provide a populated cacerts file will result in verification + errors of a certificate chain during runtime. By default an empty cacerts + file is provided and that should be fine for most JDK developers.

+
+ +

+ +
+

--with-cups=path
+ select the CUPS install location

+ +

The Common UNIX Printing System (CUPS) Headers are required for building the + OpenJDK on Solaris and Linux. The Solaris header files can be obtained by + installing the package SFWcups from the Solaris Software Companion + CD/DVD, these often will be installed into the directory /opt/sfw/cups.

+ +

The CUPS header files can always be downloaded from + www.cups.org.

+ +

--with-cups-include=path
+ select the CUPS include directory location

+ +

--with-debug-level=level
+ select the debug information level of release, fastdebug, or slowdebug

+ +

--with-dev-kit=path
+ select location of the compiler install or developer install location

+
+ +

+ +
+

--with-freetype=path
+ select the freetype files to use.

+ +

Expecting the freetype libraries under lib/ and the headers under + include/.

+ +

Version 2.3 or newer of FreeType is required. On Unix systems required files + can be available as part of your distribution (while you still may need to + upgrade them). Note that you need development version of package that + includes both the FreeType library and header files.

+ +

You can always download latest FreeType version from the FreeType + website. Building the freetype 2 libraries from + scratch is also possible, however on Windows refer to the Windows FreeType + DLL build instructions.

+ +

Note that by default FreeType is built with byte code hinting support + disabled due to licensing restrictions. In this case, text appearance and + metrics are expected to differ from Sun's official JDK build. See the + SourceForge FreeType2 Home Page + for more information.

+ +

--with-import-hotspot=path
+ select the location to find hotspot binaries from a previous build to avoid + building hotspot

+ +

--with-target-bits=arg
+ select 32 or 64 bit build

+ +

--with-jvm-variants=variants
+ select the JVM variants to build from, comma separated list that can + include: server, client, kernel, zero and zeroshark

+ +

--with-memory-size=size
+ select the RAM size that GNU make will think this system has

+ +

--with-msvcr-dll=path
+ select the msvcr100.dll file to include in the Windows builds (C/C++ + runtime library for Visual Studio).

+ +

This is usually picked up automatically from the redist directories of + Visual Studio 2013.

+ +

--with-num-cores=cores
+ select the number of cores to use (processor count or CPU count)

+
+ +

+ +
+

--with-x=path
+ select the location of the X11 and xrender files.

+ +

The XRender Extension Headers are required for building the OpenJDK on + Solaris and Linux. The Linux header files are usually available from a + "Xrender" development package, it's recommended that you try and use the + package provided by the particular distribution of Linux that you are using. + The Solaris XRender header files is included with the other X11 header files + in the package SFWxwinc on new enough versions of Solaris and will be + installed in /usr/X11/include/X11/extensions/Xrender.h or + /usr/openwin/share/include/X11/extensions/Xrender.h

+
+ +
+ +

+ +

Make

+ +

The basic invocation of the make utility looks like:

+ +
+

make all

+
+ +

This will start the build to the output directory containing the +"configuration" that was created by the configure script. Run make help for +more information on the available targets.

+ +

There are some of the make targets that are of general interest:

+ +
+

empty
+ build everything but no images

+ +

all
+ build everything including images

+ +

all-conf
+ build all configurations

+ +

images
+ create complete j2sdk and j2re images

+ +

install
+ install the generated images locally, typically in /usr/local

+ +

clean
+ remove all files generated by make, but not those generated by configure

+ +

dist-clean
+ remove all files generated by both and configure (basically killing the + configuration)

+ +

help
+ give some help on using make, including some interesting make targets

+
+ +
+ +

+ +

Testing

+ +

When the build is completed, you should see the generated binaries and +associated files in the j2sdk-image directory in the output directory. In +particular, the build/*/images/j2sdk-image/bin directory should contain +executables for the OpenJDK tools and utilities for that configuration. The +testing tool jtreg will be needed and can be found at: the jtreg +site. The provided regression tests in the +repositories can be run with the command:

+ +
+

cd test && make PRODUCT_HOME=`pwd`/../build/*/images/j2sdk-image all

+
+ +
+ +

+ +

Appendix A: Hints and Tips

+ +

+ +

FAQ

+ +

Q: The generated-configure.sh file looks horrible! How are you going to +edit it?
+A: The generated-configure.sh file is generated (think "compiled") by the +autoconf tools. The source code is in configure.ac and various .m4 files in +common/autoconf, which are much more readable.

+ +

Q: Why is the generated-configure.sh file checked in, if it is +generated?
+A: If it was not generated, every user would need to have the autoconf +tools installed, and re-generate the configure file as the first step. Our +goal is to minimize the work needed to be done by the user to start building +OpenJDK, and to minimize the number of external dependencies required.

+ +

Q: Do you require a specific version of autoconf for regenerating +generated-configure.sh?
+A: Yes, version 2.69 is required and should be easy enough to aquire on all +supported operating systems. The reason for this is to avoid large spurious +changes in generated-configure.sh.

+ +

Q: How do you regenerate generated-configure.sh after making changes to +the input files?
+A: Regnerating generated-configure.sh should always be done using the +script common/autoconf/autogen.sh to ensure that the correct files get +updated. This script should also be run after mercurial tries to merge +generated-configure.sh as a merge of the generated file is not guaranteed to +be correct.

+ +

Q: What are the files in common/makefiles/support/* for? They look like +gibberish.
+A: They are a somewhat ugly hack to compensate for command line length +limitations on certain platforms (Windows, Solaris). Due to a combination of +limitations in make and the shell, command lines containing too many files will +not work properly. These helper files are part of an elaborate hack that will +compress the command line in the makefile and then uncompress it safely. We're +not proud of it, but it does fix the problem. If you have any better +suggestions, we're all ears! :-)

+ +

Q: I want to see the output of the commands that make runs, like in the old +build. How do I do that?
+A: You specify the LOG variable to make. There are several log levels:

+ +
    +
  • warn -- Default and very quiet.
    • +
  • info -- Shows more progress information than warn.
    • +
  • debug -- Echos all command lines and prints all macro calls for +compilation definitions.
    • +
  • trace -- Echos all $(shell) command lines as well.
    • +
+ +

Q: When do I have to re-run configure?
+A: Normally you will run configure only once for creating a +configuration. You need to re-run configuration only if you want to change any +configuration options, or if you pull down changes to the configure script.

+ +

Q: I have added a new source file. Do I need to modify the makefiles?
+A: Normally, no. If you want to create e.g. a new native library, you will +need to modify the makefiles. But for normal file additions or removals, no +changes are needed. There are certan exceptions for some native libraries where +the source files are spread over many directories which also contain sources +for other libraries. In these cases it was simply easier to create include +lists rather than excludes.

+ +

Q: When I run configure --help, I see many strange options, like +--dvidir. What is this?
+A: Configure provides a slew of options by default, to all projects that +use autoconf. Most of them are not used in OpenJDK, so you can safely ignore +them. To list only OpenJDK specific features, use configure --help=short +instead.

+ +

Q: configure provides OpenJDK-specific features such as --with- +builddeps-server that are not described in this document. What about those?
+A: Try them out if you like! But be aware that most of these are +experimental features. Many of them don't do anything at all at the moment; the +option is just a placeholder. Others depend on pieces of code or infrastructure +that is currently not ready for prime time.

+ +

Q: How will you make sure you don't break anything?
+A: We have a script that compares the result of the new build system with +the result of the old. For most part, we aim for (and achieve) byte-by-byte +identical output. There are however technical issues with e.g. native binaries, +which might differ in a byte-by-byte comparison, even when building twice with +the old build system. For these, we compare relevant aspects (e.g. the symbol +table and file size). Note that we still don't have 100% equivalence, but we're +close.

+ +

Q: I noticed this thing X in the build that looks very broken by design. +Why don't you fix it?
+A: Our goal is to produce a build output that is as close as technically +possible to the old build output. If things were weird in the old build, they +will be weird in the new build. Often, things were weird before due to +obscurity, but in the new build system the weird stuff comes up to the surface. +The plan is to attack these things at a later stage, after the new build system +is established.

+ +

Q: The code in the new build system is not that well-structured. Will you +fix this?
+A: Yes! The new build system has grown bit by bit as we converted the old +system. When all of the old build system is converted, we can take a step back +and clean up the structure of the new build system. Some of this we plan to do +before replacing the old build system and some will need to wait until after.

+ +

Q: Is anything able to use the results of the new build's default make +target?
+A: Yes, this is the minimal (or roughly minimal) set of compiled output +needed for a developer to actually execute the newly built JDK. The idea is +that in an incremental development fashion, when doing a normal make, you +should only spend time recompiling what's changed (making it purely +incremental) and only do the work that's needed to actually run and test your +code. The packaging stuff that is part of the images target is not needed for +a normal developer who wants to test his new code. Even if it's quite fast, +it's still unnecessary. We're targeting sub-second incremental rebuilds! ;-) +(Or, well, at least single-digit seconds...)

+ +

Q: I usually set a specific environment variable when building, but I can't +find the equivalent in the new build. What should I do?
+A: It might very well be that we have neglected to add support for an +option that was actually used from outside the build system. Email us and we +will add support for it!

+ +

+ +

Build Performance Tips

+ +

Building OpenJDK requires a lot of horsepower. Some of the build tools can be +adjusted to utilize more or less of resources such as parallel threads and +memory. The configure script analyzes your system and selects reasonable +values for such options based on your hardware. If you encounter resource +problems, such as out of memory conditions, you can modify the detected values +with:

+ +
    +
  • --with-num-cores -- number of cores in the build system, e.g. +--with-num-cores=8
    • +
  • --with-memory-size -- memory (in MB) available in the build system, +e.g. --with-memory-size=1024
    • +
+ +

It might also be necessary to specify the JVM arguments passed to the Bootstrap +JDK, using e.g. --with-boot-jdk-jvmargs="-Xmx8G -enableassertions". Doing +this will override the default JVM arguments passed to the Bootstrap JDK.

+ +

One of the top goals of the new build system is to improve the build +performance and decrease the time needed to build. This will soon also apply to +the java compilation when the Smart Javac wrapper is fully supported.

+ +

At the end of a successful execution of configure, you will get a performance +summary, indicating how well the build will perform. Here you will also get +performance hints. If you want to build fast, pay attention to those!

+ +

Building with ccache

+ +

The OpenJDK build supports building with ccache when using gcc or clang. Using +ccache can radically speed up compilation of native code if you often rebuild +the same sources. Your milage may vary however so we recommend evaluating it +for yourself. To enable it, make sure it's on the path and configure with +--enable-ccache.

+ +

Building on local disk

+ +

If you are using network shares, e.g. via NFS, for your source code, make sure +the build directory is situated on local disk. The performance penalty is +extremely high for building on a network share, close to unusable.

+ +

Building only one JVM

+ +

The old build builds multiple JVMs on 32-bit systems (client and server; and on +Windows kernel as well). In the new build we have changed this default to only +build server when it's available. This improves build times for those not +interested in multiple JVMs. To mimic the old behavior on platforms that +support it, use --with-jvm-variants=client,server.

+ +

Selecting the number of cores to build on

+ +

By default, configure will analyze your machine and run the make process in +parallel with as many threads as you have cores. This behavior can be +overridden, either "permanently" (on a configure basis) using +--with-num-cores=N or for a single build only (on a make basis), using +make JOBS=N.

+ +

If you want to make a slower build just this time, to save some CPU power for +other processes, you can run e.g. make JOBS=2. This will force the makefiles +to only run 2 parallel processes, or even make JOBS=1 which will disable +parallelism.

+ +

If you want to have it the other way round, namely having slow builds default +and override with fast if you're impatient, you should call configure with +--with-num-cores=2, making 2 the default. If you want to run with more cores, +run make JOBS=8

+ +

+ +

Troubleshooting

+ +

Solving build problems

+ +

If the build fails (and it's not due to a compilation error in a source file +you've changed), the first thing you should do is to re-run the build with more +verbosity. Do this by adding LOG=debug to your make command line.

+ +

The build log (with both stdout and stderr intermingled, basically the same as +you see on your console) can be found as build.log in your build directory.

+ +

You can ask for help on build problems with the new build system on either the +build-dev or the +build-infra-dev +mailing lists. Please include the relevant parts of the build log.

+ +

A build can fail for any number of reasons. Most failures are a result of +trying to build in an environment in which all the pre-build requirements have +not been met. The first step in troubleshooting a build failure is to recheck +that you have satisfied all the pre-build requirements for your platform. +Scanning the configure log is a good first step, making sure that what it +found makes sense for your system. Look for strange error messages or any +difficulties that configure had in finding things.

+ +

Some of the more common problems with builds are briefly described below, with +suggestions for remedies.

+ +
    +

  • Corrupted Bundles on Windows:
    +Some virus scanning software has been known to corrupt the downloading of +zip bundles. It may be necessary to disable the 'on access' or 'real time' +virus scanning features to prevent this corruption. This type of 'real time' +virus scanning can also slow down the build process significantly. +Temporarily disabling the feature, or excluding the build output directory +may be necessary to get correct and faster builds.

    • +

  • Slow Builds:
    +If your build machine seems to be overloaded from too many simultaneous C++ +compiles, try setting the JOBS=1 on the make command line. Then try +increasing the count slowly to an acceptable level for your system. Also:

    + +

    Creating the javadocs can be very slow, if you are running javadoc, consider +skipping that step.

    + +

    Faster CPUs, more RAM, and a faster DISK usually helps. The VM build tends +to be CPU intensive (many C++ compiles), and the rest of the JDK will often +be disk intensive.

    + +

    Faster compiles are possible using a tool called +ccache.

    • +

  • File time issues:
    +If you see warnings that refer to file time stamps, e.g.

    + +
    +

    Warning message: File 'xxx' has modification time in the future.
    +Warning message: Clock skew detected. Your build may be incomplete.

    +
    + +

    These warnings can occur when the clock on the build machine is out of sync +with the timestamps on the source files. Other errors, apparently unrelated +but in fact caused by the clock skew, can occur along with the clock skew +warnings. These secondary errors may tend to obscure the fact that the true +root cause of the problem is an out-of-sync clock.

    + +

    If you see these warnings, reset the clock on the build machine, run +"gmake clobber" or delete the directory containing the build output, and +restart the build from the beginning.

    • +

  • Error message: Trouble writing out table to disk
    +Increase the amount of swap space on your build machine. This could be +caused by overloading the system and it may be necessary to use:

    + +
    +

    make JOBS=1

    +
    + +

    to reduce the load on the system.

    • +

  • Error Message: libstdc++ not found:
    +This is caused by a missing libstdc++.a library. This is installed as part +of a specific package (e.g. libstdc++.so.devel.386). By default some 64-bit +Linux versions (e.g. Fedora) only install the 64-bit version of the +libstdc++ package. Various parts of the JDK build require a static link of +the C++ runtime libraries to allow for maximum portability of the built +images.

    • +

  • Linux Error Message: cannot restore segment prot after reloc
    +This is probably an issue with SELinux (See SELinux on +Wikipedia). Parts of the VM is built +without the -fPIC for performance reasons.

    + +

    To completely disable SELinux:

    + +
      +
    1. $ su root
      2. +
    2. # system-config-securitylevel
      3. +
    3. In the window that appears, select the SELinux tab
      4. +
    4. Disable SELinux
      5. +
    + +

    Alternatively, instead of completely disabling it you could disable just +this one check.

    + +
      +
    1. Select System->Administration->SELinux Management
      2. +
    2. In the SELinux Management Tool which appears, select "Boolean" from the +menu on the left
      3. +
    3. Expand the "Memory Protection" group
      4. +
    4. Check the first item, labeled "Allow all unconfined executables to use +libraries requiring text relocation ..."
      5. +
    • +

  • Windows Error Messages:
    +*** fatal error - couldn't allocate heap, ...
    +rm fails with "Directory not empty"
    +unzip fails with "cannot create ... Permission denied"
    +unzip fails with "cannot create ... Error 50"

    + +

    The CYGWIN software can conflict with other non-CYGWIN software. See the +CYGWIN FAQ section on BLODA (applications that interfere with +CYGWIN).

    • +

  • Windows Error Message: spawn failed
    +Try rebooting the system, or there could be some kind of issue with the disk +or disk partition being used. Sometimes it comes with a "Permission Denied" +message.

    • +
+ +
+ +

+ +

Appendix B: GNU make

+ +

The Makefiles in the OpenJDK are only valid when used with the GNU version of +the utility command make (usually called gmake on Solaris). A few notes +about using GNU make:

+ +
    +
  • You need GNU make version 3.81 or newer. On Windows 4.0 or newer is +recommended. If the GNU make utility on your systems is not of a suitable +version, see "Building GNU make".
    • +
  • Place the location of the GNU make binary in the PATH.
    • +
  • Solaris: Do NOT use /usr/bin/make on Solaris. If your Solaris system +has the software from the Solaris Developer Companion CD installed, you +should try and use gmake which will be located in either the /usr/bin, +/opt/sfw/bin or /usr/sfw/bin directory.
    • +
  • Windows: Make sure you start your build inside a bash shell.
    • +
  • Mac OS X: The XCode "command line tools" must be installed on your Mac.
    • +
+ +

Information on GNU make, and access to ftp download sites, are available on the +GNU make web site . The latest +source to GNU make is available at +ftp.gnu.org/pub/gnu/make/.

+ +

+ +

Building GNU make

+ +

First step is to get the GNU make 3.81 or newer source from +ftp.gnu.org/pub/gnu/make/. Building is a +little different depending on the OS but is basically done with:

+ +
  bash ./configure
+  make
+
+ +

Appendix C: Build Environments

Minimum Build Environments

+ +

This file often describes specific requirements for what we call the "minimum +build environments" (MBE) for this specific release of the JDK. What is listed +below is what the Oracle Release Engineering Team will use to build the Oracle +JDK product. Building with the MBE will hopefully generate the most compatible +bits that install on, and run correctly on, the most variations of the same +base OS and hardware architecture. In some cases, these represent what is often +called the least common denominator, but each Operating System has different +aspects to it.

+ +

In all cases, the Bootstrap JDK version minimum is critical, we cannot +guarantee builds will work with older Bootstrap JDK's. Also in all cases, more +RAM and more processors is better, the minimums listed below are simply +recommendations.

+ +

With Solaris and Mac OS X, the version listed below is the oldest release we +can guarantee builds and works, and the specific version of the compilers used +could be critical.

+ +

With Windows the critical aspect is the Visual Studio compiler used, which due +to it's runtime, generally dictates what Windows systems can do the builds and +where the resulting bits can be used.

+ +

NOTE: We expect a change here off these older Windows OS releases and to a +'less older' one, probably Windows 2008R2 X64.

+ +

With Linux, it was just a matter of picking a stable distribution that is a +good representative for Linux in general.

+ +

NOTE: We expect a change here from Fedora 9 to something else, but it has not +been completely determined yet, possibly Ubuntu 12.04 X64, unbiased community +feedback would be welcome on what a good choice would be here.

+ +

It is understood that most developers will NOT be using these specific +versions, and in fact creating these specific versions may be difficult due to +the age of some of this software. It is expected that developers are more often +using the more recent releases and distributions of these operating systems.

+ +

Compilation problems with newer or different C/C++ compilers is a common +problem. Similarly, compilation problems related to changes to the +/usr/include or system header files is also a common problem with older, +newer, or unreleased OS versions. Please report these types of problems as bugs +so that they can be dealt with accordingly.

If you are new to +Mercurial, please see the [Beginner Guides](http://mercurial.selenic.com/wiki/ +BeginnersGuides) or refer to the [Mercurial Book](http://hgbook.red-bean.com/). +The first few chapters of the book provide an excellent overview of Mercurial, +what it is and how it works. + +For using Mercurial with the OpenJDK refer to the [Developer Guide: Installing +and Configuring Mercurial](http://openjdk.java.net/guide/ +repositories.html#installConfig) section for more information. + + +### Getting the Source + +To get the entire set of OpenJDK Mercurial repositories use the script +`get_source.sh` located in the root repository: + + hg clone http://hg.openjdk.java.net/jdk9/jdk9 YourOpenJDK + cd YourOpenJDK + bash ./get_source.sh + +Once you have all the repositories, keep in mind that each repository is its +own independent repository. You can also re-run `./get_source.sh` anytime to +pull over all the latest changesets in all the repositories. This set of +nested repositories has been given the term "forest" and there are various +ways to apply the same `hg` command to each of the repositories. For +example, the script `make/scripts/hgforest.sh` can be used to repeat the +same `hg` command on every repository, e.g. + + cd YourOpenJDK + bash ./make/scripts/hgforest.sh status + + +### Repositories + +The set of repositories and what they contain: + + * **. (root)** contains common configure and makefile logic + * **hotspot** contains source code and make files for building the OpenJDK + Hotspot Virtual Machine + * **langtools** contains source code for the OpenJDK javac and language tools + * **jdk** contains source code and make files for building the OpenJDK runtime + libraries and misc files + * **jaxp** contains source code for the OpenJDK JAXP functionality + * **jaxws** contains source code for the OpenJDK JAX-WS functionality + * **corba** contains source code for the OpenJDK Corba functionality + * **nashorn** contains source code for the OpenJDK JavaScript implementation + +### Repository Source Guidelines + +There are some very basic guidelines: + + * Use of whitespace in source files (.java, .c, .h, .cpp, and .hpp files) is + restricted. No TABs, no trailing whitespace on lines, and files should not + terminate in more than one blank line. + * Files with execute permissions should not be added to the source + repositories. + * All generated files need to be kept isolated from the files maintained or + managed by the source control system. The standard area for generated files + is the top level `build/` directory. + * The default build process should be to build the product and nothing else, + in one form, e.g. a product (optimized), debug (non-optimized, -g plus + assert logic), or fastdebug (optimized, -g plus assert logic). + * The `.hgignore` file in each repository must exist and should include + `^build/`, `^dist/` and optionally any `nbproject/private` directories. **It + should NEVER** include anything in the `src/` or `test/` or any managed + directory area of a repository. + * Directory names and file names should never contain blanks or non-printing + characters. + * Generated source or binary files should NEVER be added to the repository + (that includes `javah` output). There are some exceptions to this rule, in + particular with some of the generated configure scripts. + * Files not needed for typical building or testing of the repository should + not be added to the repository. + +***** + + +## Building + +The very first step in building the OpenJDK is making sure the system itself +has everything it needs to do OpenJDK builds. Once a system is setup, it +generally doesn't need to be done again. + +Building the OpenJDK is now done with running a `configure` script which will +try and find and verify you have everything you need, followed by running +`make`, e.g. + +> **`bash ./configure`** +> **`make all`** + +Where possible the `configure` script will attempt to located the various +components in the default locations or via component specific variable +settings. When the normal defaults fail or components cannot be found, +additional `configure` options may be necessary to help `configure` find the +necessary tools for the build, or you may need to re-visit the setup of your +system due to missing software packages. + +**NOTE:** The `configure` script file does not have execute permissions and +will need to be explicitly run with `bash`, see the source guidelines. + +***** + + +### System Setup + +Before even attempting to use a system to build the OpenJDK there are some very +basic system setups needed. For all systems: + + * Be sure the GNU make utility is version 3.81 (4.0 on windows) or newer, e.g. + run "`make -version`" + + + * Install a Bootstrap JDK. All OpenJDK builds require access to a previously + released JDK called the _bootstrap JDK_ or _boot JDK._ The general rule is + that the bootstrap JDK must be an instance of the previous major release of + the JDK. In addition, there may be a requirement to use a release at or + beyond a particular update level. + + **_Building JDK 9 requires JDK 8. JDK 9 developers should not use JDK 9 as + the boot JDK, to ensure that JDK 9 dependencies are not introduced into the + parts of the system that are built with JDK 8._** + + The JDK 8 binaries can be downloaded from Oracle's [JDK 8 download + site](http://www.oracle.com/technetwork/java/javase/downloads/index.html). + For build performance reasons it is very important that this bootstrap JDK + be made available on the local disk of the machine doing the build. You + should add its `bin` directory to the `PATH` environment variable. If + `configure` has any issues finding this JDK, you may need to use the + `configure` option `--with-boot-jdk`. + + * Ensure that GNU make, the Bootstrap JDK, and the compilers are all in your + PATH environment variable. + +And for specific systems: + + * **Linux** + + Install all the software development packages needed including + [alsa](#alsa), [freetype](#freetype), [cups](#cups), and + [xrender](#xrender). See [specific system packages](#SDBE). + + * **Solaris** + + Install all the software development packages needed including [Studio + Compilers](#studio), [freetype](#freetype), [cups](#cups), and + [xrender](#xrender). See [specific system packages](#SDBE). + + * **Windows** + + * Install one of [CYGWIN](#cygwin) or [MinGW/MSYS](#msys) + * Install [Visual Studio 2013](#vs2013) + + * **Mac OS X** + + Install [XCode 4.5.2](https://developer.apple.com/xcode/) and also + install the "Command line tools" found under the preferences pane + "Downloads" + + +#### Linux + +With Linux, try and favor the system packages over building your own or getting +packages from other areas. Most Linux builds should be possible with the +system's available packages. + +Note that some Linux systems have a habit of pre-populating your environment +variables for you, for example `JAVA_HOME` might get pre-defined for you to +refer to the JDK installed on your Linux system. You will need to unset +`JAVA_HOME`. It's a good idea to run `env` and verify the environment variables +you are getting from the default system settings make sense for building the +OpenJDK. + + +#### Solaris + + +##### Studio Compilers + +At a minimum, the [Studio 12 Update 1 Compilers](http://www.oracle.com/ +technetwork/server-storage/solarisstudio/downloads/index.htm) (containing +version 5.10 of the C and C++ compilers) is required, including specific +patches. + +The Solaris SPARC patch list is: + + * 118683-05: SunOS 5.10: Patch for profiling libraries and assembler + * 119963-21: SunOS 5.10: Shared library patch for C++ + * 120753-08: SunOS 5.10: Microtasking libraries (libmtsk) patch + * 128228-09: Sun Studio 12 Update 1: Patch for Sun C++ Compiler + * 141860-03: Sun Studio 12 Update 1: Patch for Compiler Common patch for Sun C + C++ F77 F95 + * 141861-05: Sun Studio 12 Update 1: Patch for Sun C Compiler + * 142371-01: Sun Studio 12.1 Update 1: Patch for dbx + * 143384-02: Sun Studio 12 Update 1: Patch for debuginfo handling + * 143385-02: Sun Studio 12 Update 1: Patch for Compiler Common patch for Sun C + C++ F77 F95 + * 142369-01: Sun Studio 12.1: Patch for Performance Analyzer Tools + +The Solaris X86 patch list is: + + * 119961-07: SunOS 5.10_x86, x64, Patch for profiling libraries and assembler + * 119964-21: SunOS 5.10_x86: Shared library patch for C++\_x86 + * 120754-08: SunOS 5.10_x86: Microtasking libraries (libmtsk) patch + * 141858-06: Sun Studio 12 Update 1_x86: Sun Compiler Common patch for x86 + backend + * 128229-09: Sun Studio 12 Update 1_x86: Patch for C++ Compiler + * 142363-05: Sun Studio 12 Update 1_x86: Patch for C Compiler + * 142368-01: Sun Studio 12.1_x86: Patch for Performance Analyzer Tools + +Place the `bin` directory in `PATH`. + +The Oracle Solaris Studio Express compilers at: [Oracle Solaris Studio Express +Download site](http://www.oracle.com/technetwork/server-storage/solarisstudio/ +downloads/index-jsp-142582.html) are also an option, although these compilers +have not been extensively used yet. + + +#### Windows + +##### Windows Unix Toolkit + +Building on Windows requires a Unix-like environment, notably a Unix-like +shell. There are several such environments available of which +[Cygwin](http://www.cygwin.com/) and +[MinGW/MSYS](http://www.mingw.org/wiki/MSYS) are currently supported for the +OpenJDK build. One of the differences of these systems from standard Windows +tools is the way they handle Windows path names, particularly path names which +contain spaces, backslashes as path separators and possibly drive letters. +Depending on the use case and the specifics of each environment these path +problems can be solved by a combination of quoting whole paths, translating +backslashes to forward slashes, escaping backslashes with additional +backslashes and translating the path names to their ["8.3" +version](http://en.wikipedia.org/wiki/8.3_filename). + + +###### CYGWIN + +CYGWIN is an open source, Linux-like environment which tries to emulate a +complete POSIX layer on Windows. It tries to be smart about path names and can +usually handle all kinds of paths if they are correctly quoted or escaped +although internally it maps drive letters `:` to a virtual directory +`/cygdrive/`. + +You can always use the `cygpath` utility to map pathnames with spaces or the +backslash character into the `C:/` style of pathname (called 'mixed'), e.g. +`cygpath -s -m ""`. + +Note that the use of CYGWIN creates a unique problem with regards to setting +[`PATH`](#path). Normally on Windows the `PATH` variable contains directories +separated with the ";" character (Solaris and Linux use ":"). With CYGWIN, it +uses ":", but that means that paths like "C:/path" cannot be placed in the +CYGWIN version of `PATH` and instead CYGWIN uses something like +`/cygdrive/c/path` which CYGWIN understands, but only CYGWIN understands. + +The OpenJDK build requires CYGWIN version 1.7.16 or newer. Information about +CYGWIN can be obtained from the CYGWIN website at +[www.cygwin.com](http://www.cygwin.com). + +By default CYGWIN doesn't install all the tools required for building the +OpenJDK. Along with the default installation, you need to install the following +tools. + +> + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

+ +Note that the CYGWIN software can conflict with other non-CYGWIN software on +your Windows system. CYGWIN provides a [FAQ](http://cygwin.com/faq/ +faq.using.html) for known issues and problems, of particular interest is the +section on [BLODA (applications that interfere with +CYGWIN)](http://cygwin.com/faq/faq.using.html#faq.using.bloda). + + +###### MinGW/MSYS + +MinGW ("Minimalist GNU for Windows") is a collection of free Windows specific +header files and import libraries combined with GNU toolsets that allow one to +produce native Windows programs that do not rely on any 3rd-party C runtime +DLLs. MSYS is a supplement to MinGW which allows building applications and +programs which rely on traditional UNIX tools to be present. Among others this +includes tools like `bash` and `make`. See [MinGW/MSYS](http://www.mingw.org/ +wiki/MSYS) for more information. + +Like Cygwin, MinGW/MSYS can handle different types of path formats. They are +internally converted to paths with forward slashes and drive letters +`:` replaced by a virtual directory `/`. Additionally, MSYS +automatically detects binaries compiled for the MSYS environment and feeds them +with the internal, Unix-style path names. If native Windows applications are +called from within MSYS programs their path arguments are automatically +converted back to Windows style path names with drive letters and backslashes +as path separators. This may cause problems for Windows applications which use +forward slashes as parameter separator (e.g. `cl /nologo /I`) because MSYS may +wrongly [replace such parameters by drive letters](http://mingw.org/wiki/ +Posix_path_conversion). + +In addition to the tools which will be installed by default, you have to +manually install the `msys-zip` and `msys-unzip` packages. This can be easily +done with the MinGW command line installer: + + mingw-get.exe install msys-zip + mingw-get.exe install msys-unzip + + +##### Visual Studio 2013 Compilers + +The 32-bit and 64-bit OpenJDK Windows build requires Microsoft Visual Studio +C++ 2013 (VS2013) Professional Edition or Express compiler. The compiler and +other tools are expected to reside in the location defined by the variable +`VS120COMNTOOLS` which is set by the Microsoft Visual Studio installer. + +Only the C++ part of VS2013 is needed. Try to let the installation go to the +default install directory. Always reboot your system after installing VS2013. +The system environment variable VS120COMNTOOLS should be set in your +environment. + +Make sure that TMP and TEMP are also set in the environment and refer to +Windows paths that exist, like `C:\temp`, not `/tmp`, not `/cygdrive/c/temp`, +and not `C:/temp`. `C:\temp` is just an example, it is assumed that this area +is private to the user, so by default after installs you should see a unique +user path in these variables. + + +#### Mac OS X + +Make sure you get the right XCode version. + +***** + + +### Configure + +The basic invocation of the `configure` script looks like: + +> **`bash ./configure [options]`** + +This will create an output directory containing the "configuration" and setup +an area for the build result. This directory typically looks like: + +> **`build/linux-x64-normal-server-release`** + +`configure` will try to figure out what system you are running on and where all +necessary build components are. If you have all prerequisites for building +installed, it should find everything. If it fails to detect any component +automatically, it will exit and inform you about the problem. When this +happens, read more below in [the `configure` options](#configureoptions). + +Some examples: + +> **Windows 32bit build with freetype specified:** +> `bash ./configure --with-freetype=/cygdrive/c/freetype-i586 --with-target- +bits=32` + +> **Debug 64bit Build:** +> `bash ./configure --enable-debug --with-target-bits=64` + + +#### Configure Options + +Complete details on all the OpenJDK `configure` options can be seen with: + +> **`bash ./configure --help=short`** + +Use `-help` to see all the `configure` options available. You can generate any +number of different configurations, e.g. debug, release, 32, 64, etc. + +Some of the more commonly used `configure` options are: + +> **`--enable-debug`** +> set the debug level to fastdebug (this is a shorthand for `--with-debug- + level=fastdebug`) + + +> **`--with-alsa=`**_path_ +> select the location of the Advanced Linux Sound Architecture (ALSA) + +> Version 0.9.1 or newer of the ALSA files are required for building the + OpenJDK on Linux. These Linux files are usually available from an "alsa" of + "libasound" development package, and it's highly recommended that you try + and use the package provided by the particular version of Linux that you are + using. + +> **`--with-boot-jdk=`**_path_ +> select the [Bootstrap JDK](#bootjdk) + +> **`--with-boot-jdk-jvmargs=`**"_args_" +> provide the JVM options to be used to run the [Bootstrap JDK](#bootjdk) + +> **`--with-cacerts=`**_path_ +> select the path to the cacerts file. + +> See [Certificate Authority on Wikipedia](http://en.wikipedia.org/wiki/ + Certificate_Authority) for a better understanding of the Certificate + Authority (CA). A certificates file named "cacerts" represents a system-wide + keystore with CA certificates. In JDK and JRE binary bundles, the "cacerts" + file contains root CA certificates from several public CAs (e.g., VeriSign, + Thawte, and Baltimore). The source contain a cacerts file without CA root + certificates. Formal JDK builders will need to secure permission from each + public CA and include the certificates into their own custom cacerts file. + Failure to provide a populated cacerts file will result in verification + errors of a certificate chain during runtime. By default an empty cacerts + file is provided and that should be fine for most JDK developers. + + +> **`--with-cups=`**_path_ +> select the CUPS install location + +> The Common UNIX Printing System (CUPS) Headers are required for building the + OpenJDK on Solaris and Linux. The Solaris header files can be obtained by + installing the package **SFWcups** from the Solaris Software Companion + CD/DVD, these often will be installed into the directory `/opt/sfw/cups`. + +> The CUPS header files can always be downloaded from + [www.cups.org](http://www.cups.org). + +> **`--with-cups-include=`**_path_ +> select the CUPS include directory location + +> **`--with-debug-level=`**_level_ +> select the debug information level of release, fastdebug, or slowdebug + +> **`--with-dev-kit=`**_path_ +> select location of the compiler install or developer install location + + +> **`--with-freetype=`**_path_ +> select the freetype files to use. + +> Expecting the freetype libraries under `lib/` and the headers under + `include/`. + +> Version 2.3 or newer of FreeType is required.

How are you going to +edit it? +**A:** The `generated-configure.sh` file is generated (think "compiled") by the +autoconf tools. The source code is in `configure.ac` and various .m4 files in +common/autoconf, which are much more readable. + +**Q:** Why is the `generated-configure.sh` file checked in, if it is +generated? +**A:** If it was not generated, every user would need to have the autoconf +tools installed, and re-generate the `configure` file as the first step. Our +goal is to minimize the work needed to be done by the user to start building +OpenJDK, and to minimize the number of external dependencies required. + +**Q:** Do you require a specific version of autoconf for regenerating +`generated-configure.sh`? +**A:** Yes, version 2.69 is required and should be easy enough to aquire on all +supported operating systems. The reason for this is to avoid large spurious +changes in `generated-configure.sh`. + +**Q:** How do you regenerate `generated-configure.sh` after making changes to +the input files? +**A:** Regnerating `generated-configure.sh` should always be done using the +script `common/autoconf/autogen.sh` to ensure that the correct files get +updated. This script should also be run after mercurial tries to merge +`generated-configure.sh` as a merge of the generated file is not guaranteed to +be correct. + +**Q:** What are the files in `common/makefiles/support/*` for? They look like +gibberish. +**A:** They are a somewhat ugly hack to compensate for command line length +limitations on certain platforms (Windows, Solaris). Due to a combination of +limitations in make and the shell, command lines containing too many files will +not work properly. These helper files are part of an elaborate hack that will +compress the command line in the makefile and then uncompress it safely. We're +not proud of it, but it does fix the problem. If you have any better +suggestions, we're all ears! :-) + +**Q:** I want to see the output of the commands that make runs, like in the old +build. How do I do that? +**A:** You specify the `LOG` variable to make. There are several log levels: + + * **`warn`** -- Default and very quiet. + * **`info`** -- Shows more progress information than warn. + * **`debug`** -- Echos all command lines and prints all macro calls for + compilation definitions. + * **`trace`** -- Echos all $(shell) command lines as well. + +**Q:** When do I have to re-run `configure`? +**A:** Normally you will run `configure` only once for creating a +configuration. You need to re-run configuration only if you want to change any +configuration options, or if you pull down changes to the `configure` script. + +**Q:** I have added a new source file. Do I need to modify the makefiles? +**A:** Normally, no. If you want to create e.g. a new native library, you will +need to modify the makefiles. But for normal file additions or removals, no +changes are needed. There are certan exceptions for some native libraries where +the source files are spread over many directories which also contain sources +for other libraries. In these cases it was simply easier to create include +lists rather than excludes. + +**Q:** When I run `configure --help`, I see many strange options, like +`--dvidir`. What is this? +**A:** Configure provides a slew of options by default, to all projects that +use autoconf. Most of them are not used in OpenJDK, so you can safely ignore +them. To list only OpenJDK specific features, use `configure --help=short` +instead. + +**Q:** `configure` provides OpenJDK-specific features such as `--with- +builddeps-server` that are not described in this document. What about those? +**A:** Try them out if you like! But be aware that most of these are +experimental features. Many of them don't do anything at all at the moment; the +option is just a placeholder. Others depend on pieces of code or infrastructure +that is currently not ready for prime time. + +**Q:** How will you make sure you don't break anything? +**A:** We have a script that compares the result of the new build system with +the result of the old. For most part, we aim for (and achieve) byte-by-byte +identical output. There are however technical issues with e.g. native binaries, +which might differ in a byte-by-byte comparison, even when building twice with +the old build system. For these, we compare relevant aspects (e.g. the symbol +table and file size). Note that we still don't have 100% equivalence, but we're +close. + +**Q:** I noticed this thing X in the build that looks very broken by design. +Why don't you fix it? +**A:** Our goal is to produce a build output that is as close as technically +possible to the old build output. If things were weird in the old build, they +will be weird in the new build. Often, things were weird before due to +obscurity, but in the new build system the weird stuff comes up to the surface. +The plan is to attack these things at a later stage, after the new build system +is established. + +**Q:** The code in the new build system is not that well-structured. Will you +fix this? +**A:** Yes! The new build system has grown bit by bit as we converted the old +system. When all of the old build system is converted, we can take a step back +and clean up the structure of the new build system. Some of this we plan to do +before replacing the old build system and some will need to wait until after. + +**Q:** Is anything able to use the results of the new build's default make +target? +**A:** Yes, this is the minimal (or roughly minimal) set of compiled output +needed for a developer to actually execute the newly built JDK. The idea is +that in an incremental development fashion, when doing a normal make, you +should only spend time recompiling what's changed (making it purely +incremental) and only do the work that's needed to actually run and test your +code. The packaging stuff that is part of the `images` target is not needed for +a normal developer who wants to test his new code. Even if it's quite fast, +it's still unnecessary. We're targeting sub-second incremental rebuilds! ;-) +(Or, well, at least single-digit seconds...) + +**Q:** I usually set a specific environment variable when building, but I can't +find the equivalent in the new build. What should I do? +**A:** It might very well be that we have neglected to add support for an +option that was actually used from outside the build system. Email us and we +will add support for it! + + +### Build Performance Tips + +Building OpenJDK requires a lot of horsepower. Some of the build tools can be +adjusted to utilize more or less of resources such as parallel threads and +memory. The `configure` script analyzes your system and selects reasonable +values for such options based on your hardware. If you encounter resource +problems, such as out of memory conditions, you can modify the detected values +with: + + * **`--with-num-cores`** -- number of cores in the build system, e.g. + `--with-num-cores=8` + * **`--with-memory-size`** -- memory (in MB) available in the build system, + e.g. `--with-memory-size=1024` + +It might also be necessary to specify the JVM arguments passed to the Bootstrap +JDK, using e.g. `--with-boot-jdk-jvmargs="-Xmx8G -enableassertions"`. Doing +this will override the default JVM arguments passed to the Bootstrap JDK. + +One of the top goals of the new build system is to improve the build +performance and decrease the time needed to build. This will soon also apply to +the java compilation when the Smart Javac wrapper is fully supported. + +At the end of a successful execution of `configure`, you will get a performance +summary, indicating how well the build will perform. Here you will also get +performance hints. If you want to build fast, pay attention to those! + +#### Building with ccache + +The OpenJDK build supports building with ccache when using gcc or clang. Using +ccache can radically speed up compilation of native code if you often rebuild +the same sources. Your milage may vary however so we recommend evaluating it +for yourself. To enable it, make sure it's on the path and configure with +`--enable-ccache`. + +#### Building on local disk + +If you are using network shares, e.g. via NFS, for your source code, make sure +the build directory is situated on local disk. The performance penalty is +extremely high for building on a network share, close to unusable. + +#### Building only one JVM + +The old build builds multiple JVMs on 32-bit systems (client and server; and on +Windows kernel as well). In the new build we have changed this default to only +build server when it's available. This improves build times for those not +interested in multiple JVMs. To mimic the old behavior on platforms that +support it, use `--with-jvm-variants=client,server`. + +#### Selecting the number of cores to build on + +By default, `configure` will analyze your machine and run the make process in +parallel with as many threads as you have cores. This behavior can be +overridden, either "permanently" (on a `configure` basis) using +`--with-num-cores=N` or for a single build only (on a make basis), using +`make JOBS=N`. + +If you want to make a slower build just this time, to save some CPU power for +other processes, you can run e.g. `make JOBS=2`. This will force the makefiles +to only run 2 parallel processes, or even `make JOBS=1` which will disable +parallelism. + +If you want to have it the other way round, namely having slow builds default +and override with fast if you're impatient, you should call `configure` with +`--with-num-cores=2`, making 2 the default. If you want to run with more cores, +run `make JOBS=8` + + +### Troubleshooting + +#### Solving build problems + +If the build fails (and it's not due to a compilation error in a source file +you've changed), the first thing you should do is to re-run the build with more +verbosity. Do this by adding `LOG=debug` to your make command line. + +The build log (with both stdout and stderr intermingled, basically the same as +you see on your console) can be found as `build.log` in your build directory. + +You can ask for help on build problems with the new build system on either the +[build-dev](http://mail.openjdk.java.net/mailman/listinfo/build-dev) or the +[build-infra-dev](http://mail.openjdk.java.net/mailman/listinfo/build-infra-dev) +mailing lists. Please include the relevant parts of the build log. + +A build can fail for any number of reasons. Most failures are a result of +trying to build in an environment in which all the pre-build requirements have +not been met. The first step in troubleshooting a build failure is to recheck +that you have satisfied all the pre-build requirements for your platform. +Scanning the `configure` log is a good first step, making sure that what it +found makes sense for your system. Look for strange error messages or any +difficulties that `configure` had in finding things. + +Some of the more common problems with builds are briefly described below, with +suggestions for remedies. + + * **Corrupted Bundles on Windows:** + Some virus scanning software has been known to corrupt the downloading of + zip bundles. It may be necessary to disable the 'on access' or 'real time' + virus scanning features to prevent this corruption. This type of 'real time' + virus scanning can also slow down the build process significantly. + Temporarily disabling the feature, or excluding the build output directory + may be necessary to get correct and faster builds. + + * **Slow Builds:** + If your build machine seems to be overloaded from too many simultaneous C++ + compiles, try setting the `JOBS=1` on the `make` command line. Then try + increasing the count slowly to an acceptable level for your system. Also: + + Creating the javadocs can be very slow, if you are running javadoc, consider + skipping that step. + + Faster CPUs, more RAM, and a faster DISK usually helps. The VM build tends + to be CPU intensive (many C++ compiles), and the rest of the JDK will often + be disk intensive. + + Faster compiles are possible using a tool called + [ccache](http://ccache.samba.org/). + + * **File time issues:** + If you see warnings that refer to file time stamps, e.g. + + > _Warning message:_ ` File 'xxx' has modification time in the future.` + > _Warning message:_ ` Clock skew detected. Your build may be incomplete.` + + These warnings can occur when the clock on the build machine is out of sync + with the timestamps on the source files. Other errors, apparently unrelated + but in fact caused by the clock skew, can occur along with the clock skew + warnings. These secondary errors may tend to obscure the fact that the true + root cause of the problem is an out-of-sync clock. + + If you see these warnings, reset the clock on the build machine, run + "`gmake clobber`" or delete the directory containing the build output, and + restart the build from the beginning. + + * **Error message: `Trouble writing out table to disk`** + Increase the amount of swap space on your build machine. This could be + caused by overloading the system and it may be necessary to use: + + > `make JOBS=1` + + to reduce the load on the system. + + * **Error Message: `libstdc++ not found`:** + This is caused by a missing libstdc++.a library. This is installed as part + of a specific package (e.g. libstdc++.so.devel.386). By default some 64-bit + Linux versions (e.g. Fedora) only install the 64-bit version of the + libstdc++ package. Various parts of the JDK build require a static link of + the C++ runtime libraries to allow for maximum portability of the built + images. + + * **Linux Error Message: `cannot restore segment prot after reloc`** + This is probably an issue with SELinux (See [SELinux on + Wikipedia](http://en.wikipedia.org/wiki/SELinux)). Parts of the VM is built + without the `-fPIC` for performance reasons. + + To completely disable SELinux: + + 1. `$ su root` + 2. `# system-config-securitylevel` + 3. `In the window that appears, select the SELinux tab` + 4. `Disable SELinux` + + Alternatively, instead of completely disabling it you could disable just + this one check. + + 1. Select System->Administration->SELinux Management + 2. In the SELinux Management Tool which appears, select "Boolean" from the + menu on the left + 3. Expand the "Memory Protection" group + 4. Check the first item, labeled "Allow all unconfined executables to use + libraries requiring text relocation ..." + + * **Windows Error Messages:** + `*** fatal error - couldn't allocate heap, ... ` + `rm fails with "Directory not empty"` + `unzip fails with "cannot create ... Permission denied"` + `unzip fails with "cannot create ... Error 50"` + + The CYGWIN software can conflict with other non-CYGWIN software. See the + CYGWIN FAQ section on [BLODA (applications that interfere with + CYGWIN)](http://cygwin.com/faq/faq.using.html#faq.using.bloda). + + * **Windows Error Message: `spawn failed`** + Try rebooting the system, or there could be some kind of issue with the disk + or disk partition being used. Sometimes it comes with a "Permission Denied" + message. + +***** + + +## Appendix B: GNU make + +The Makefiles in the OpenJDK are only valid when used with the GNU version of +the utility command `make` (usually called `gmake` on Solaris). A few notes +about using GNU make: + + * You need GNU make version 3.81 or newer. On Windows 4.0 or newer is + recommended. If the GNU make utility on your systems is not of a suitable + version, see "[Building GNU make](#buildgmake)". + * Place the location of the GNU make binary in the `PATH`. + * **Solaris:** Do NOT use `/usr/bin/make` on Solaris. If your Solaris system + has the software from the Solaris Developer Companion CD installed, you + should try and use `gmake` which will be located in either the `/usr/bin`, + `/opt/sfw/bin` or `/usr/sfw/bin` directory. + * **Windows:** Make sure you start your build inside a bash shell. + * **Mac OS X:** The XCode "command line tools" must be installed on your Mac. + +Information on GNU make, and access to ftp download sites, are available on the +[GNU make web site ](http://www.gnu.org/software/make/make.html). The latest +source to GNU make is available at +[ftp.gnu.org/pub/gnu/make/](http://ftp.gnu.org/pub/gnu/make/). + + +### Building GNU make + +First step is to get the GNU make 3.81 or newer source from +[ftp.gnu.org/pub/gnu/make/](http://ftp.gnu.org/pub/gnu/make/). Building is a +little different depending on the OS but is basically done with: + + bash ./configure + make + +***** + + +## Appendix C: Build Environments + +### Minimum Build Environments + +This file often describes specific requirements for what we call the "minimum +build environments" (MBE) for this specific release of the JDK. What is listed +below is what the Oracle Release Engineering Team will use to build the Oracle +JDK product. Building with the MBE will hopefully generate the most compatible +bits that install on, and run correctly on, the most variations of the same +base OS and hardware architecture. In some cases, these represent what is often +called the least common denominator, but each Operating System has different +aspects to it. + +In all cases, the Bootstrap JDK version minimum is critical, we cannot +guarantee builds will work with older Bootstrap JDK's. Also in all cases, more +RAM and more processors is better, the minimums listed below are simply +recommendations. + +With Solaris and Mac OS X, the version listed below is the oldest release we +can guarantee builds and works, and the specific version of the compilers used +could be critical. + +With Windows the critical aspect is the Visual Studio compiler used, which due +to it's runtime, generally dictates what Windows systems can do the builds and +where the resulting bits can be used. + +**NOTE: We expect a change here off these older Windows OS releases and to a +'less older' one, probably Windows 2008R2 X64.** + +With Linux, it was just a matter of picking a stable distribution that is a +good representative for Linux in general. + +**NOTE: We expect a change here from Fedora 9 to something else, but it has not +been completely determined yet, possibly Ubuntu 12.04 X64, unbiased community +feedback would be welcome on what a good choice would be here.** + +It is understood that most developers will NOT be using these specific +versions, and in fact creating these specific versions may be difficult due to +the age of some of this software. It is expected that developers are more often +using the more recent releases and distributions of these operating systems. + +Compilation problems with newer or different C/C++ compilers is a common +problem. Similarly, compilation problems related to changes to the +`/usr/include` or system header files is also a common problem with older, +newer, or unreleased OS versions. Please report these types of problems as bugs +so that they can be dealt with accordingly. + +> + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
