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
Attempting to read file `Device.chs'...
...parsing `Device'...
...successfully loaded `Device'.

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

$ 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.
Probably relevant:
