Building and Packaging OpenJDK9 for OSX
Some pre-requisites are required to build OpenJDK9 on OSX and recent macOS versions such as Sierra.
Install XCode for you operating system version, including Command Line Tools. XCode should be activated via xcode-select:
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
You could find them on Brew or MacPorts sites.
Ruby 1.9 have issues in build so you should be sure Ruby 1.8 or 2.0 (Yosemite or later) is used. You can check the current Ruby version using:
ruby --version
If you're using rbenv, you can set the operating system's Ruby version as default:
rbenv local system
X11 is required for building, so it should be installed on Mountain Lion or later, since such versions don't provide it anymore. Hopefully XQuartz could be used.
Note: XQuartz forgot to install X11 "include" directory in the correct location so, fix it with a symlink:
-
For OSX El Captain, macOS Sierra and later:
sudo ln -s /usr/X11/include/X11 /usr/local/include/X11 -
For OSX El Captain, macOS Sierra and later:
sudo ln -s /usr/X11/include/X11 /usr/include/X11
A JDK for Java 8 must be installed. You should use Oracle Java8 since OpenJDK8 is not recommended for OpenJDK9 build.
For example, you want to build OpenJDKs in openjdkathome directory under your home directory:
mkdir ~/openjdkathome
cd ~/openjdkathome
git clone https://github.com/hgomez/obuildfactory.git
Building is activated by XBUILD env var set to true:
cd ~/openjdkathome
XUSE_NEW_BUILD_SYSTEM=true XBUILD=true ./obuildfactory/openjdk9/macosx/standalone-job.sh
After some minutes you should see this logs:

mbp-rico:openjdkathome henri$ java -version

Packaging is activated by XPACKAGE env var set to true:
cd ~/openjdkathome

DMG files are located under OBF_DROP_DIR/openjdk9 OpenJDK8 will be installed under /Library/Java/JavaVirtualMachines/1.9.0.jdk
To test newly installed OpenJDK, set JAVA_HOME:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/1.9.0.jdk/Contents/Home
mbp-rico:openjdkathome henri$ java -version

OpenJDK could be built with debug mode, called fast-debug.
In this mode JVM will provide much more informations via flags like -XX:+UnlockDiagnosticVMOptions -XX:+PrintAssembly
To active debug mode, set XDEBUG to true ie:
cd ~/openjdkathome
XDEBUG=true XBUILD=true XPACKAGE=true ./obuildfactory/openjdk9/macosx/standalone-job.sh
Debug Tarballs, DMGs and bundle dir will contains fastdebug.
By default, build are performed in incremental mode, ie only updated code is recompiled, reducing overall build time.
But experience in OpenJDK show that weird things happens sometimes and it's better to start from scratch and perform a clean build.
To activate clean mode, use XCLEAN env var ie:
cd ~/openjdkathome
XCLEAN=true XBUILD=true XPACKAGE=true ./obuildfactory/openjdk9/macosx/standalone-job.sh
