haskell - wxHaskell 在 win7 上，找不到 wxc.dll 或 .so

Question

我已经在 windows7 上安装了 wxwidget 和 wxhaskell（使用 cabal），我做了一个 test.hs

import Graphics.UI.WX

main :: IO ()
main = start gui

gui :: IO ()
gui = do f <- frame [text := "Hello"]
         inp <- entry f []
         out <- entry f []
         but <- button f [ text := "Hello"
                        , on command := do s <- get inp text;
                                           set out [text := "Hello "++s]
                         ]
         set f [ layout := floatCentre $ column 5
                            [ label "What is your name?"
                            , widget inp
                            , widget but
                            , widget out
                            ] ]

然后我在winGHCi中加载并运行test.hs，这是输出

"ghci> " :load "test.hs"
[1 of 1] Compiling Main             ( test.hs, interpreted )
Ok, modules loaded: Main.
"ghci> " main
can't load .so/.DLL for: C:\Users\zhaijy\AppData\Roaming\cabal\x86_64-windows-ghc-7.10.2\wxc-0.92.1.1-2q6ESjcRWaMHNPxrdblcRv\wxc.dll (addDLL: could not load DLL)
"ghci> " 

我不知道如何解决这个问题。我需要做什么/添加/更改才能加载 DLL？

这是一个 GHCi 错误；它在 GHC 7.10.3 中得到解决
