Missing Maurice…

Thursday, June 4th, 2009

Today would have marked Maurice’s 30th birthday, if it weren’t for that unfortunate accident almost a year ago. It is times like these when you remember the loss of a valued friend more so than normally. No more sharing of cake, taunting the additional year and celebrating life.

My iCal notified me yesterday of Maurice’s upcoming birthday, and today again. It will keep on doing that next year, and the year after that…

Maurice you are sorely missed. My thoughts are with you and Michel and your family. Where ever you are, happy birthday!

Eclipse 3.4 with openjdk 6 on OS X 32-bit CoreDuo

Tuesday, June 2nd, 2009

With the invaluable help of David Green, I was able to run Eclipse on openjdk 6 on my first gen MacBook Pro (you know, those left behind by Apple, running on a 32 bit CoreDuo processor… good to know that Apple supports the early adapters).

With this script that I adapted from David’s blog I was able to start Eclipse 3.4 (Version: 3.4.2
Build id: M20090211-1700) with Landon Fullers openjdk 6 build:

export JAVA_HOME=/Developer/Java/openjdk6-b16-24_apr_2009-r1
export PATH=$JAVA_HOME/bin:$PATH

java -server -Djava.library.path=$HOME/bin/jnilib -Dswt.library.path=$HOME/bin/jnilib -Xms128m -Xmx768m \
    -XX:MaxPermSize=192m -Dosgi.requiredJavaVersion=1.5 -Dorg.eclipse.swt.internal.carbon.smallFonts \
    -cp /Applications/eclipse/Eclipse.app/Contents/MacOS/../../../plugins/org.eclipse.equinox.launcher_1.0.101.R34x_v20081125.jar \
    org.eclipse.equinox.launcher.Main -os macosx -ws carbon -arch x86 -showsplash \
    -launcher /Applications/eclipse/Eclipse.app/Contents/MacOS/eclipse -name Eclipse \
    --launcher.library /Applications/eclipse/Eclipse.app/Contents/MacOS/../../../plugins/org.eclipse.equinox.launcher.carbon.macosx_1.0.101.R34x_v20080731 \
    -startup /Applications/eclipse/Eclipse.app/Contents/MacOS/../../../plugins/org.eclipse.equinox.launcher_1.0.101.R34x_v20081125.jar \
    -launcher /Applications/eclipse/Eclipse.app/Contents/MacOS/eclipse \
    -keyring $HOME.eclipse_keyring -consoleLog -showlocation -vm $JAVA_HOME

The script misses the shebang, since my hosting provider thinks that I’m trying to execute some serverside exploit…
You’ll have to extract a couple of shared libraries that are packaged in your Eclipse distribution:

jar xfv /Applications/eclipse/plugins/org.eclipse.swt.carbon.macosx_3.4.1.v3452b.jar
jar xfv /Applications/eclipse/plugins/org.eclipse.core.filesystem.macosx_*.jar os/macosx/liblocalfile_1_0_0.jnilib

You’ll have to rename all those libraries to give them a *.dylib extension.

Finally I had to point /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home to the openjdk 6 directory:

sudo mv /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home.old
sudo ln -s LOCATION_OF_OPENJDK /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
