I am trying to find the Nvidia OpenCL SDK. No luck so fare.
I am starting to give up so I am asking here in case someone can cast some light on the issue.
I believe you have to download and install the CUDA toolkit (which helpfully makes no mention of OpenCL whatsoever) over at https://developer.nvidia.com/cuda-downloads
NVIDIA OpenCL header files are in: C:\Program Files (x86)\NVIDIA GPU Computing Toolkit\CUDA\v5.5\include\CL
just experimented a bit now : linux ... first - only one platform is good idea, so better to check
/etc/OpenCL/vendors
and remove intel and amd ...*icd
CFLAGS=-I/usr/local/cuda/include make # worked
from older notes:
OCL examples here for your convenience
yum -y install gcc libXmu-devel
