运行Haskell& NSInternalInconsistencyException SDL计划

我试图在OSX 10.8.2,SDL 1.2.15,GHC 7.4.2,haskell SDL绑定0.6.4上编译并运行一个简单的SDL程序:

import Graphics.UI.SDL as SDL

main :: IO ()
main = do
    screen <- setVideoMode 640 480 32 [SWSurface]
    hello <- loadBMP "hello.bmp"

    blitSurface hello Nothing screen Nothing

    SDL.flip screen

    delay 2000

它编译(ghc test.hs)没有错误,但是当我尝试运行它时,我得到以下异常:

$ ./test

据我了解,这与main()有关 - 替换技巧SDL执行。我查看了其他几个使用SDL的Haskell应用程序;我设法编译的那些显示相同的行为(这可能指向我的特定配置的一些问题)。一个例外是Eternal10Seconds,它使用-no-hs-main ghc选项和一些.c / .h魔法。这是必要的,还是有更明确的方法来使事情有效?

对不起信息噪音,但我自己设法解决了。似乎.c魔法是不可避免的,但它需要一些努力才能使它与cabal一起使用。根据{{​​3}}和example from haskell-SDL repo,我将TimePiece放在一起。我打算扩展它以使其真正跨平台(因为我自己也需要它)。
