无法在64位Linux上安装Haskell CUDA

Question

我在64位Arch Linux上使用cabal安装/构建haskell-cuda时遇到了问题。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...
[ 1 of 27] Compiling Foreign.CUDA.Driver.Error ( dist/build/Foreign/CUDA/Driver/Error.hs, dist/build/Foreign/CUDA/Driver/Error.o )
[ 2 of 27] Compiling Foreign.CUDA.Internal.Offsets ( dist/build/Foreign/CUDA/Internal/Offsets.hs, dist/build/Foreign/CUDA/Internal/Offsets.o )
[ 3 of 27] Compiling Foreign.CUDA.Internal.C2HS ( Foreign/CUDA/Internal/C2HS.hs, dist/build/Foreign/CUDA/Internal/C2HS.o )
[ 4 of 27] Compiling Foreign.CUDA.Driver.Utils ( dist/build/Foreign/CUDA/Driver/Utils.hs, dist/build/Foreign/CUDA/Driver/Utils.o )

Foreign/CUDA/Driver/Utils.chs:35:23:
    Illegal type signature: `IO (Status, Int) cuDriverGetVersion'
      Perhaps you intended to use -XScopedTypeVariables

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Hackage上的源代码错误，但我可能误解了，这是我的机器的错误。无论哪种方式，我应该如何着手修复它呢？

Answer 1

好的，看起来(基于this)问题实际上是0.16.6版本中的c2hs程序的错误

解决方案是降级到版本0.16.5，然后再次尝试安装CUDA。

cabal install c2hs-0.16.5
cabal install cuda

在降级后，安装进行得很完美！
