How many OpenCL implementations do you have installed? gl_interop_demo.py silently uses the first one (that should probably be fixed, patches welcome), but if that is not the AMD one (/the one corresponding to the GL driver), then that would explain your error. HTH, Andreas PS: PLEASE keep the list cc'd on problems like this. For archival, and also to help reduce my workload.
