haskell - OS X 10.9.5 上的 nvcc + c2hs

Question

我正在构建一个需要 nvcc 的软件用于编译。我没有支持 CUDA 的 GPU，但实际上我不需要它——一个 friend 正在 Linux 上构建完全相同的软件，他没有 CUDA GPU，但一切都很好。

我从 https://developer.nvidia.com/cuda-downloads 安装了最新的 CUDA 工具包( cuda_6.5.14_mac_64.pkg ) 没有问题。但是当我构建软件时，我遇到了问题。

我能够在较小的范围内重现该问题:

$ 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

#include "cbits/stubs.h"
         ^

c2hs: Error during preprocessing custom header file

有了痕迹，我就可以更深入地进入兔子洞:

$ 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)

我不知道如何解决这个问题。顺便说一句， clang和 gcc可以通过 -D 传递带有参数的宏.

根据 https://github.com/haskell/c2hs/issues/111 ，在 11 月 21 日，更改被推送到 c2hs HEAD 来解决这个问题，这是由 nvcc 中的上游怪癖引起的。所以此时，使用最新的c2hs确实应该工作。
