    The Build Group has a wiki page with Supported Build Platforms. From time to time, this is updated by contributors to list successes or failures of building on different platforms.

    It's possible to build both Windows and Linux binaries from WSL. To build Windows binaries, you must use a Windows boot JDK (located in a Windows-accessible directory). To build Linux binaries, you must use a Linux boot JDK. The default behavior is to build for Windows. To build for Linux, pass --build=x86_64-unknown-linux-gnu --host=x86_64-unknown-linux-gnu to configure.

    If building Windows binaries, the source code must be located in a Windows- accessible directory. This is because Windows executables (such as Visual Studio and the boot JDK) must be able to access the source code. Also, the drive where the source is stored must be mounted as case-insensitive by changing either /etc/fstab or /etc/wsl.conf in WSL. Individual directories may be corrected using the fsutil tool in case the source was cloned before changing the mount options.

    Note that while it's possible to build on WSL, testing is still not fully supported.

    macOS

    Apple is using a quite aggressive scheme of pushing OS updates, and coupling these updates with required updates of Xcode. Unfortunately, this makes it difficult for a project such as the JDK to keep pace with a continuously updated machine running macOS. See the section on Apple Xcode on some strategies to deal with this.

    It is recommended that you use at least Mac OS X 10.13 (High Sierra). At the time of writing, the JDK has been successfully compiled on macOS 10.12 (Sierra).

To use a specific version of Xcode, use xcode-select -s before running configure, or use --with-toolchain-path to point to the version of Xcode to use, e.g. configure --with-toolchain-path=/Applications/Xcode8.app/Contents/Developer/usr/bin

    Note that configure locates and verifies a properly functioning version of make and stores the path to this make binary in the configuration. If you start a build using make on the command line, you will be using the version of make found first in your PATH, and not necessarily the one stored in the configuration. This initial make will be used as "bootstrap make", and in a second stage, the make located by configure will be called. Normally, this will present no issues, but if you have a very old make, or a non-GNU Make make in your path, this might cause issues.

    If you want to override the default make found by configure, use the MAKE configure variable, e.g. configure MAKE=/opt/gnu/make.

    If you are prepared to take some risk of an incorrect build, and know enough of the system to understand how things build and interact, you can speed up the build process considerably by instructing make to only build a portion of the product.

    Building Individual Modules

    The safe way to use fine-grained make targets is to use the module specific make targets. All source code in the JDK is organized so it belongs to a module, e.g. java.base or jdk.jdwp.agent. You can build only a specific module, by giving it as make target: make jdk.jdwp.agent. If the specified module depends on other modules (e.g. java.base), those modules will be built first.

    Identifies a signal handler frame on the stack.

    - -

    There are a few different algorithms for doing this, and - they vary from platform to platform. For example, based on a - conversation with Dave Dice, Solaris/x86 will be substantially - simpler to handle than Solaris/SPARC because the signal handler - frame can be identified because of a program counter == -1.

    - -

    The dbx group provided code and advice on these topics; the - code below evolved from theirs, but is not correct/robust. - Without going into too many details, it seems that looking for - the incoming argument to the sigacthandler frame (which is what - this code identifies) is not guaranteed to be stable across - versions of Solaris, since that function is supplied by - libthread and is not guaranteed not to clobber I2 before it - calls __sighndlr later. From discussions, it sounds like a - robust algorithm which wouldn't require traversal of the - ucontext chain (used by dbx, but which Dave Dice thinks isn't - robust in the face of libthread -- need to follow up) would be - to be able to properly identify the __sighndlr frame, then get - I2 and treat that as a ucontext. To identify __sighndlr we would - need to look up that symbol in the remote process and look for a - program counter within a certain (small) distance.

    - -

    If the underlying Debugger supports CDebugger interface, we - take the approach of __sighnldr symbol. This approach is more robust - compared to the original hueristic approach. Of course, if there - is no CDebugger support, we fallback to the hueristic approach.

    - -

    The current implementation seems to work with Solaris 2.8. - A nice property of this system is that if we find a core file - this algorithm doesn't work on, we can change the code and try - again, so I'm putting this in as the current mechanism for - finding signal handler frames on Solaris/SPARC.
