I've just started to learn OpenCL and wanted to use CodeXL to debug more easily.
My system :
- NVIDIA GPU GeForce GTX 650
- Intel(R) Xeon(R) CPU E5430 2.66Hz
- Linux RedHat 6
When I start CodeXL it requires an AMD GPU. I'd like to know why I can't debug the kernel even if it's launched on CPU?
Is there anyway with my setup to debug with CodeXL .
Otherwise I tried with GDB and I can enter the kernel but I have to pass -O0 in addition to -g to the program's compiler options.
And it's not really easy to debug like that since I don't know how to isolate some thread and watch values.
I hope you'll be able to help.
