This file should be located at the top of the OpenJDK Mercurial root

repository. This root repository will include a "make" directory,
|

and a Makefile for building the entire OpenJDK.

A full OpenJDK repository set (forest) should also include the following

6 nested repositories:

the following 6 nested repositories:
|

"jdk", "hotspot", "langtools", "corba", "jaxws" and "jaxp".
|
||||
There are also several source downloads for the jax* repositories that

will be needed.

This one root repository can be obtained with something like:

To make sure you have all the nested repositories, you can run the

Simple Build Instructions:
|
||||
|
||||
0. Get the necessary system software/packages installed on your system, see
|
||||
http://hg.openjdk.java.net/jdk8/build/raw-file/tip/README-builds.html
|
||||
http://hg.openjdk.java.net/jdk8/jdk8/raw-file/tip/README-builds.html
|
||||
|
||||
1. If you don't have a jdk6 installed, download and install a JDK 6 from
|
||||
1. If you don't have a jdk7u7 or newer jdk, download and install it from
|
||||
http://java.sun.com/javase/downloads/index.jsp
|
||||
Set the environment variable ALT_BOOTDIR to the location of JDK 6.
|
||||
Add the /bin directory of this installation to your PATH environment
|
||||
variable.
|
||||
|
||||
2. Check the sanity of doing a build with your current system:
|
||||
make sanity
|
||||
See README-builds.html if you run into problems.
|
||||
2. Configure the build:
|
||||
bash ./configure
|
||||
|
||||
3. Do a complete build of the OpenJDK:
|
||||
3. Build the OpenJDK:
|
||||
make all
|
||||
The resulting JDK image should be found in build/*/j2sdk-image
|
||||
The resulting JDK image should be found in build/*/images/j2sdk-image
|
||||
|
||||
where make is GNU make 3.81 or newer, /usr/bin/make on Linux usually
|
||||
is 3.81 or newer.
|
||||
is 3.81 or newer. Note that on Solaris, GNU make is called "gmake".
