Mac OS X Port

Goals

See main project page: http://openjdk.java.net/projects/macosx-port/

Prerequisites

Hardware: Any 64-bit capable Intel Mac
- RAM: 4GB, 2GB min
OS: Mac OS X 10.6, run Software Update to get to at least 10.6.7
Xcode: 3.2.6 or later from http://developer.apple.com (Mac Dev Center section)
Java: "Java for Mac OS X 10.6 Update 4" or later from http://connect.apple.com (Java section)
Mercurial: http://mercurial.berkwood.com/
Jtreg: http://openjdk.java.net/jtreg/

Source

hg clone http://hg.openjdk.java.net/macosx-port/macosx-port
cd macosx-port
chmod 755 get_source.sh
./get_source.sh

Build

make ALLOW_DOWNLOADS=true SA_APPLE_BOOT_JAVA=true ALWAYS_PASS_TEST_GAMMA=true ALT_BOOTDIR=`/usr/libexec/java_home -v 1.6`

Smoke Test

$ build/macosx-universal/j2sdk-bundle/1.7.0.jdk/Contents/Home/bin/java -version

Install

mkdir -p ~/Library/Java/JavaVirtualMachines
cp -R build/macosx-universal/j2sdk-bundle/1.7.0.jdk ~/Library/Java/JavaVirtualMachines

The "1.7.0.jdk" bundle can be copied or symlinked to ~/Library/Java/JavaVirtualMachines or /Library/Java/JavaVirtualMachines.

Once installed, the build will be discovered by /Applications/Utilities/Java Preferences.app, and found using the /usr/libexec/java_home tool, when passing it "--version 1.7".

By dragging the 1.7.0 version to the top of the Java Preferences lists, it will become the default JVM for command line use (since CommandLine is currently the only capability it supports).

Run

export JAVA_HOME=`/usr/libexec/java_home --version 1.7`
$JAVA_HOME/bin/java -version

Test

jtreg is the test harness used by the OpenJDK test framework. The script linux/jtreg is a shell script that runs fine on Mac OS X. It will run all the tests under $SRC/jdk/.

By default jtreg will use the current jvm for running both the test harness and the tests themselves.

The examples below use the jtreg option -jdk to specify the JDK compiled in the macosx-port source directory.

Example: running all the jdk tests (takes a long time):

cd <path-to-macosx-port-source>/jdk/
<path to jtreg>/linux/bin/jtreg -jdk:../build/macosx-universal/j2sdk-bundle/1.7.0.jdk/Contents/Home/ -v:summary test

Example: running just the jdk java/lang tests (approximately 340 tests; completes in about 6 minutes):

cd <path-to-macosx-port-source>/jdk/
<path to jtreg>/linux/bin/jtreg -jdk:../build/macosx-universal/j2sdk-bundle/1.7.0.jdk/Contents/Home/ -v:summary test/java/lang

If you run jtreg by making a symbolic link to linux/jtreg in another directory already on your PATH you will need to export a JT_HOME environmental variable.
