CLGLTexture2d.java bug and fix

Hello,

I'm not sure if I should report this somewhere else, but. I've just begin working on a new spare time project of mine for ray tracing in OpenCL, and thought I would share a texture from OpenCL (the produced framebuffer) with OpenGL (so I don't need to download to cpu and then upload again to gpu).

The JOCL and JOGL Java wrappers are nice, however, when trying to create a shared texture with the wrapped methods I've run into a problem (works fine with the low level bindings btw).

I believe the createFromGLTexture2d method in the CLGLTexture2d class is broken.

The line (it reports error on success ^^ because you feed it with the image ref id instead of the previous return code :))
   checkForError((int)id, "can not share memory with texture #"+texture+".");
is wrong, it should be:
   checkForError(result[0], "can not share memory with texture #"+texture+".");

I havent tested the rest of the fcn, so there mgiht be more problems there.

jocl 2.0 rc5



Cheers,
//Me

Did I report this in the wrong place?

Looks good.

To fix this bug we have to find some time to start maintaining JOCL,
so this won't happen right away. Maybe you or somebody else likes
to give it a shot ?
