使用haskell原产地的Cabal安装unix-2.7.0.1软件包

Question

一切都是从杂耍开始的。

我在我的Windows7机器上安装了“崇高3”的SublimeHaskell包，并收到警告说找不到hdevtools，或者类似的东西。所以我想我可以试着用Cabal安装那个软件包。

我已经安装了Cygwin，在我的道路上工作得很好。我尝试了一个cabal install hdevtools，我得到了一些可怕的东西：

Resolving dependencies...

Warning: Unknown extensions: CApiFFI, InterruptibleFFI

cygwin warning:

  CYGWIN environment variable option "nodosfilewarning" turns off this warning.

..。(许多看上去不错的支票)

cabal: Package unix-2.7.0.1 can't be built on this system.
Failed to install unix-2.7.0.1
cabal: Error: some packages failed to install:
hdevtools-0.1.0.5 depends on unix-2.7.0.1 which failed to install.
unix-2.7.0.1 failed during the building phase. The exception was:
ExitFailure 1

所以我想，也许我应该安装unix-2.7.0.1软件包。这是一个cabal install unix-2.7.0.1。实际上，我最终得到的输出似乎完全相同，阴谋告诉我，unix-2.7.0.1根本不能建立在我的系统上。当我尝试通过下载.tar文件手动构建它，并在一个看似成功的runhaskell Setup configure之后用runhaskell Setup build配置/构建它时，我得到了同样的结果。

有人能告诉我为什么我不能在我的Windows 7机器上构建unix-2.7.0.1吗？

根据http://hackage.haskell.org/package/unix，在windows下不支持unix包，它提供对unix系统库的绑定。
