nvcc + c2hs on OS X 10.9.5

Question

I'm building a software that needs nvcc for compilation. I don't have a CUDA-capable GPU, but actually I don't need that – a friend is building the exact same software on Linux, he has no CUDA GPU, but everything's fine.

I installed the newest CUDA toolkit from https://developer.nvidia.com/cuda-downloads (cuda_6.5.14_mac_64.pkg) without an issue. But as I was building the software I got into problems.

I was able to reproduce the issue on the smaller scale:

$ mkdir temp; cd temp; cabal sandbox init


$ cabal get cuda
Unpacking to cuda-0.6.5.0/


$ cd cuda-0.6.5.0/Foreign/CUDA/Analysis


$ c2hs -d trace --cpp=/Developer/NVIDIA/CUDA-6.5/bin/nvcc --cppopts=-ccbin --cppopts=/usr/bin/clang --cppopts=-Xcompiler --cppopts=--stdlib=libstdc++ Device.chs

         ^

c2hs: Error during preprocessing custom header file

With the trace in hand, I was able to go deeper into the rabbit hole:

$ /Developer/NVIDIA/CUDA-6.5/bin/nvcc -E -x c -ccbin /usr/bin/clang -Xcompiler --stdlib=libstdc++ -U__BLOCKS__ -DC2HS_MIN_VERSION(mj,mn,rv)=(mj<=0&&mn<=18&&rv<=2) Device.chs.h

$ Developer/NVIDIA/CUDA-6.5/bin/nvcc -x c -D 'C2HS_MIN_VERSION(mj,mn,rv)=(mj<=0&&mn<=18&&rv<=2)' Device.chs.h
(same issue)

I have no idea how to fix that. By the way, both clang and gcc are okay with passing macros with arguments via -D.

As per https://github.com/haskell/c2hs/issues/111, on November 21 a change was pushed to c2hs HEAD to work around the issue, which was caused by an upstream quirk in nvcc. So at this point, using the latest c2hs should indeed work.
