無法在64位Linux上安裝Haskell CUDA

Question

我在64位Arch Linux上使用cabal安裝/構建haskell-cuda時遇到了問題。據我所知，我有所有的先決條件（即，CUDA運行時庫，NVC編譯器等）。

我得到的錯誤如下：

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)

[ 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 
    In a pattern type-signature 
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 

據我瞭解，這是與Hackage源的錯誤，但是我可能誤會了，這是我的機器上的錯誤。無論哪種方式，我應該如何解決它？

好了，這樣看來（基於this），這個問題實際上與c2hs程序中的錯誤，在版本0.16.6

的解決方案是降級到0.16.5版本，並從那裏，再次嘗試安裝CUDA。

cabal install c2hs-0.16.5 
cabal install cuda 

降級後，安裝完成！
