Please, someone help me solve it. This is very important for me to debug my compiler CL kernel generation phase.
I dont think so you can use printf in the kernel code. The extension which you are specifying , make sure that your hardware/compilier supports that. It would be helpful to debug if you can give the clinfo of your system.
Why are you using 3.0 Beta ? The actual release in available, in which they fixed the printf bug.
Please upgrade to the full release.
