I am back with yet another beginner question.

I've got a project running Ok on mac and Windows, now I am trying to test it on Linux SUSE (11, Enterprise SP1, 64bit) and I am running into some issues.

I am using the native libraries packaged in jocl-0.9-b13-20110303-linux-i586.7z -- I only need gluegen and jocl so I am using libgluegen-rt.so and libjocl.so (where on mac I was using libgluegen-rt.jnilib and libjocl.dylib).

This is what I get when I run it:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /lib/libjocl.so: /lib/libjocl.so: wrong ELF class: ELFCLASS64 (Possible cause: architecture word width mismatch)

Where's the catch?

Any help appreciated!
