页面：(http://en.wikibooks.org/wiki/
Haskell/GUI)描述了要运行wx代码,可以安装wx,然后必须“使用GHC注册wxHaskell” – 但是我认为wxHaskell的二进制安装程序(http://wxhaskell.sourceforge.net/download.html)自动执行？
我安装了wx-config,然后安装了wxPack和wxHaskell.然后安装了wx和wxcore.我正在从Leksah运行一些wx演示,这似乎很好 – 但是他们有一些奇怪的错误(我发现一个所谓的解决方案：“wxhaskell-labels-cant-display-full-text”),但是我想尝试一些只是从GHCi.
我试着运行他们简单的演示,错误：

还有[有趣]的错误：

(GHC version 7.0.3 for i386-unknown-mingw32):

Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
这似乎是wxHaskell,GHCi和Windows的组合的已知问题.从
http://www.haskell.org/haskellwiki/WxHaskell/Quick_start
On Windows 7,ghci will complain “can’t load .so/.DLL for: std c++ …”. But
ghc --make Hello.hs; Hello.exeon the command line works well.
所以,你可以编译你的代码.你只是无法通过翻译来运行它.
