无法在64位Linux上安装Haskell CUDA

在64位Arch Linux上使用cabal安装/构建haskell cuda时遇到问题。据我所知，我有所有的先决条件（即cuda运行时库、nvcc编译器等）

我得到的错误如下：

cabal install cuda
[all tests pass]
Building cuda-0.5.1.1...
Preprocessing library cuda-0.5.1.1...

    Illegal type signature: `IO (Status, Int) cuDriverGetVersion'

Failed to install cuda-0.5.1.1
cabal: Error: some packages failed to install:
cuda-0.5.1.1 failed during the building phase. The exception was:
ExitFailure 1

据我所知，这是黑客攻击源的一个错误，但我可能误解了，这是我的机器的一个错误。不管怎样，我应该如何着手修复它？

好的，看来（基于）问题实际上是0.16.6版c2hs程序的故障

解决方案是降级到0.16.5版本，然后再尝试安装CUDA

cabal install c2hs-0.16.5
cabal install cuda

降级后，安装进行得非常顺利
