Installing amd opencl platform breaks previously working nvidia platform.
Hi,
I've been using an NVIDIA opencl platform successfully for a while. Then I installed the AMD stream sdk as well in order to test some of my opencl code on the cpu. Now I get weird segmentation faults whenever I query the platforms on the system.
The output from CLInfo is attached.
Any suggestions or comments are appreciated.
Cheers,
Dominic
