Building and Packaging OpenJDK8 for OSX
Some pre-requisites are required to build OpenJDK8 on OSX.
Install XCode 4.5.x on Mountain Lion or XCode 4.4 on Lion with Command Line Tools installed
xcode should be activated via xcode-select
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
If you installed Command Line Tools, xcode-select should be
sudo xcode-select -switch /Library/Developer/CommandLineTools
You could find them on Brew or MacPorts sites.
Ruby 1.9 have issues in build so you should be sure Ruby 1.8 is used. If you're using rbenv, you could use :
rbenv local system
X11 is required for building so it should installed on Lion.
Mountain Lion didn't provide it anymore but hopefully XQuartz could be used. Note, XQuartz forgot to install X11 include in correct location so fix it with symlink
sudo ln -s /usr/X11/include/X11 /usr/include/X11
Java 7 should be installed, you could use Oracle Java7 or OpenJDK7 built from OBuildfactory :-)
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/openjdk8/macosx/standalone-job.sh
After some minutes you should see this logs :

Set JAVA_HOME to test it :
mbp-rico:openjdkathome henri$ export JAVA_HOME=`pwd`/jdk1.8.0.jdk/Contents/Home
mbp-rico:openjdkathome henri$ java -version
openjdk version "1.8.0-b62"
OpenJDK Runtime Environment (build 1.8.0-b62-20121028)
OpenJDK 64-Bit Server VM (build 25.0-b06, mixed mode)
Packaging is activated by XPACKAGE env var set to true
cd ~/openjdkathome
XBUILD=true XPACKAGE=true ./obuildfactory/openjdk8/macosx/standalone-job.sh
DMG files are located under OBF_DROP_DIR/openjdk8 OpenJDK8 will be installed under /Library/Java/JavaVirtualMachines/1.8.0.jdk
To test newly installed OpenJDK, set JAVA_HOME
export JAVA_HOME=/Library/Java/JavaVirtualMachines/1.8.0.jdk/Contents/Home
mbp-rico:openjdkathome henri$ java -version
openjdk version "1.8.0-b62"

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/openjdk8/macosx/standalone-job.sh
Debug Tarballs, DMGs and bundle dir will contains fastdebug :

-rw-r--r-- 1 henri staff 46 26 oct 18:07 j2sdk-image-fastdebug-x86_64-b62-20121028.tar.bz2
Debug packages install names also include fastdebug, allowing to install release and debug packages at same time :
/Library/Java/JavaVirtualMachines/1.8.0.jdk/
/Library/Java/JavaVirtualMachines/1.8.0.jre/
/Library/Java/JavaVirtualMachines/1.8.0-fastdebug.jdk/
/Library/Java/JavaVirtualMachines/1.8.0-fastdebug.jre/
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/openjdk8/macosx/standalone-job.sh
