JOGL and Snow leopard

Question

Hi everyone,

I'm having some major issues with getting JOGL to work on snow leopard.

I've installed all the necessary JOGL jars in

/system/library/java/extensions

I can get sample code to compile but when I attempt to run it it throws the error following error on trying to actually display the window.

Exception in thread "main" java.lang.RuntimeException: Unable to initialize JAWT

Has anyone seen this error before and if they have how did you fix it?

Regards

James

EDIT: This error appears using both Java 1.5 and Java 1.6 and I've tried JOGL beta 5, beta 10 and the nightly builds

Answer 1

What build of JOGL are you using, and what version of Java (1.5 or 1.6)? There was some talk of the beta 5 release having this issue. I found this link. It's a shot in the dark but without more information it's all I have.

JOGL Kenai Link

I was able to download a version of JOGL from the following link

JOGL JSR 231 Beta 10

I downloaded the mac universal zip and was able to get it working by putting the jars on the classpath and pointing the java.library.path to the the directory I unzipped the archive to. The archive includes all of the .so files you need to get JOGL running. I don't think you need all of the jars included here. There seem to be a lot of files related to the CDC, which I think is a mobile platform if memory serves. I didn't include these in my test.

I didn't get the error you mentioned and am running Snow Leopard on a Core Duo MacBook Pro. The used the source from the Gears demo and it ran without a hitch. I even switched out the Frame with a JFrame to see if that would change anything. It worked fine both ways. You may want to try with this library and see if that works for you.
