what do you mean if you say installed? How are you starting your
application? Those exceptions could be caused by mixing different
gluegen/jocl versions.

0.9.1 is a little bit experimental, but it ran well on all systems i
tested on.

I deleted the older version of JOCL from my hard drive and removed it from my build path. Then I downloaded https://github.com/downloads/mbien/jocl/jocl-0.9-bmanual-20110810-windows-amd64.zip and extracted all contents to a folder within my eclipse workspace. Finally I added the new gluegen-rt.jar and jocl.jar to my build path.

i see - thats a very common mistake.
JOCL requires native libraries for execution, those are located in the
foo-natives-*.jars and must be in the java.library.path which you can
set with -Djava.library.path="foo" as explained in the wiki.

there is now a more convenient way to use jocl, however you will have to
download the latest build:
https://github.com/downloads/mbien/jocl/jocl-0.9.1-bmanual-20110811-linux-win-mac-bundle.zip

just put all jocl and gluegen-rt jars into classpath and you should be
set. With all jars i mean jocl.jar, gluegen-rt.jar and the corresponding
*-natives-*.jars.

i will continue to tweak the bundeling and hope to simplify things with
time. (next step is to reduce jar count)

regards,
michael

thanks, I will try it soon. Weird, I think I didn't have to do that on my workstation.... can you point me to the wiki entry you refer to? I cant find it.
