6 years ago Hi Austin,
I have not seen this error before. In general OpenCL on Mac is not as stable as on Windows and Linux for some reason, kernels that run fine on Windows and Linux suddenly break on Mac.

I'm testing out first-level analysis using BROCCOLI with some data I'd previously analyzed with FSL. When I run FirstLevelAnalysis using my CPU as the OpenCL device, everything builds perfectly fine and the analysis seems to run as intended. When I try running the same analysis with my GPU, however, I get the following error:
Source build error for kernelBayesian.cpp is CL_BUILD_PROGRAM_FAILURE One or several kernels were not created correctly, check buildInfo* !
Looking at the build log for that file for my GPU, it contains just this single line:
ptxas error : Program using constant pointers passed as entry function parameter cannot use cvta.const
The only reference I could turn up to this error on Google was another OpenCL developer having the same issue on a Mac https://devtalk.nvidia.com/default/topic/1015746/possible-compiler-bug-in-mac-nvidia-web-driver-346-03-15f08-on-osx-10-11-6/, but he never posted a solution. Here's my GetOpenCLInfo output:

I've tried installing the NVIDIA Web Drivers and CUDA drivers for my GPU to see if that would make a difference, but without any luck. I'm running macOS 10.13.4 (High Sierra). Any idea what's going on?
Thanks in advance!
