[Beignet] Sample program crash with beignet 0.3 on IVB

Thanks your help, it works.

I tried this opencl example :

http://wiki.tiker.net/OpenCLHowTo#Testing

and it shows these supported extensions by IVB:

NAME: Intel HD Graphics Family
VENDOR: Intel
PROFILE: FULL_PROFILE
VERSION: OpenCL 1.2 beignet 0.3
EXTENSIONS: cl_khr_global_int32_base_atomics
cl_khr_global_int32_extended_atomics cl_khr_local_int32_base_atomics
cl_khr_local_int32_extended_atomics cl_khr_byte_addressable_store
cl_khr_icd cl_khr_gl_sharing
DRIVER_VERSION: 0.3


but when I use opencv with opencl I gave CL_BUILD_PROGRAM_FAILURE error.
I think the problem is opencv want to use cl_khr_fp64 extension and beignet
doesnt support yet or not ?

What can I do ?

Thanks again.
