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

Downloading the internet with Maven in a new light

Tuesday, May 19th, 2009

I have my share of complaints like everybody else about Apache Maven and one of them is that upon installation (or upgrading to a new plugin version) it starts downloading half of the available internet. Maven is constructed in a highly modular fashion, requiring lots of different, small, focused Java libraries. I’d like the distribution to contain those libraries, but I digress. Tonight I saw that not only Maven is structured this way. It is something *all* open source projects got.

For example, the much touted Ruby on Rails project with their disdain for everything Java would probably cringe at Maven (it uses XML after all). But installing Ruby on Rails and for example Radiant CMS with some plugins is a futile attempt in finding the right invocations of: script/*, rake, gem, port and other commandline tools you’ll want to get familiar with. All these tools start downloading stuff from the internet from different repositories (SVN, ruby forge, etc).

Maven: you’re not alone anymore in downloading the internet for your builds…

How I revived my HP ScanJet 3300c on OS X

Sunday, June 8th, 2008

I had this old scanner laying around and found the need to scan some old photos. Of course I could take a picture of the picture using a 10MP digital camera, but somehow that isn’t as pretty or convenient as just scanning.

Apparently I didn’t search well enough for OS X scanner support last time I wanted to scan something. If you go looking for support for your old trusted Windows scanner after you’ve migrated to OS X, you may run into the same trouble I got myself in. Fortunately open source developers have provided the world with a set of drivers for OS X that enables your old trusted scanner under OS X. W00T!

Developers of TWAIN SANE: THANKS!

OS X: Logitech 250 USB headset works on Leopard

Tuesday, May 13th, 2008

In a previous post, which happens to be high on Google’s search results when looking for OS X drivers and Logitech products, I lamented Logitech’s driver support for not working and mostly keeping quiet about it.

I’ve recently upgraded my MacBook Pro to Leopard and it seems that the freezing problem has been fixed. I haven’t encountered the spinning beach ball of death due to connecting my Logitech headset. But I must confess that I am very cautious currently when attaching the headset, and haven’t used it for a while. I’m slightly optimistic that this problem is solved.

Logitech: OS X’s Achilles heel?

Tuesday, December 18th, 2007

I am the (currently not so proud) owner of a Logitech 250 USB headset that gives my patience a run for its money. Whenever I revive my Mac Book Pro (first generation core duo) and plug the USB headset into one of the USB ports, OS X grinds to a halt.

I’m not the only one who faces this problem. I can attest to the experience in that support discussion: it doesn’t matter in which USB port I plug the headset, or even if it is linked through my cinema display’s USB hub. The only thing I can add is that this happens when my mac book has been asleep.

Last time I complained on this blog about a thing that bugged me on OS X, it got resolved pretty quickly, so here’s hoping for us Logitech 250 owners!
