Any ideas on how to resolve the problem with the cl_khr_gl_sharing extension in the SimpleGL sample application?

Thanks!

Please explain how this is supposed to fix the issue.

/opt/AMDAPP/samples/opencl/cl/app/SimpleGL$ export LD_LIBRARY_PATH=/usr/lib/fglrx/

It appears it does not fix the issue in my case.

it seems that you have already set LD_LIBRARY_PATH. then try this export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/fglrx or export LD_LIBRARY_PATH=/usr/lib/fglrx:$LD_LIBRARY_PATH
