I currently have CUDA 5.0 installed under MAC OSX Mountain Lion (10.8) and I can compile code and everything file. I also need OpenCL as well. I tried installing an older version of the NVIDIA GPU Computing SDK to see if I could get OpenCL code to compile but to no avail. It is always missing oclUtils.h for some reason. Could anyone explain to me how to install and compile OpenCL codes on MAC OSX Mountain Lion or point me in the direction of someone I could talk to for some help? Thanks.
