Exception: function `get_current_opengl_sharegroup` returned NULL. Did you create an openGL context yet?

python setup.py build

sudo python setup.py install

These examples work fine: add_vectors.py, and print_device_info.py

But gl_interop_demo.py fails with the following error:

cos@cos-laptop:~/oclpb/examples$ python gl_interop_demo.py

I'm running xubuntu 11.10 with the nvidia 295.40 driver. the video card is a Quadro NVS 160.

The pyglet/pyopengl pyopencl interop stuff is working for me still do you think they may be conflicting with your stuff?

I will also post this to your github issues page in case if anyone else runs into it.

Thanks a million for your time. I'll also try this on my desktop at home with a gtx260.

@ubernaut this is an incredibly simple fix, but I haven't had access to a non-mac machine in a while.

If you are familiar with OpenCL, take a look in opencl.clgl.set_opengl_properties and add system specific statement there.

I'll probably get to this in less than a week.
