gephi 0.8.1 issue on Mac X 10.8.2 unable to load libjogl_awt.jnilib

Question

I'm new to JAVA. I'm on Mac OS X 10.8.2. Using gephi 0.8.1. I get:

echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/1.6.0_33-b03-424.jdk/Contents/Home
echo $JDK_HOME
/Library/Java/JavaVirtualMachines/1.6.0_33-b03-424.jdk/Contents/Home

gephi libs list:

/Applications/gephi.app/Contents/Resources/gephi/gephi/modules/lib/macosx-universal/libjogl.jnilib
/Applications/gephi.app/Contents/Resources/gephi/gephi/modules/lib/macosx-universal/libjogl_awt.jnilib
/Applications/gephi.app/Contents/Resources/gephi/gephi/modules/lib/macosx-universal/libjogl_cg.jnilib

Launching gephi from clicking icon won't work, I need to use command line:

./gephi --jdkhome /Library/Java/JavaVirtualMachines/1.6.0_33-b03-424.jdk/Contents/Home

After this I get 'Unable to load libjogl_awt.jnilib'

Any suggestions on what I can do to fix my JAVA environment -- or at least start gephi? Thx.

UPDATE: As suggested in gephi forums, I've also linked /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK to /Library/Java/JavaVirtualMachines/1.6.0_33-b03-424.jdk/Contents and have the 32-bit Java first in Java preferences...

Answer 1

You can try to delete the gephi settings folder under /Your_username/Library/Application support/gephi and run it again.

Answer 2

To run Gephi on OS X Mavericks, just install the Apple's update for Java 6 http://support.apple.com/kb/DL1572?viewlocale=en_US

If you still have problems it probably means that you have Java 7 installed, and Gephi is using it. You can override that behavior by editing Gephi's config file:

Open /Applications/Gephi.app/Contents/Resources/gephi/etc/gephi.conf and set the jdkhome value to:

jdkhome="/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home"

Answer 3

I re-installed Java for OSX 2012-006 and gephi now works -- don't know why.
