構建問題，使用macops庫與GHC

Question

我想跟隨tutorial的圖表庫haskell。

我已經安裝了開羅和gtk2hs macports。

但是當我嘗試運行實例教程，我得到以下錯誤：

$ ghc --make diagramsTutorial.lhs 
Linking diagramsTutorial ... 
ld: warning: in /opt/local/lib/libgtk-x11-2.0.dylib, file was built for unsupported file format which is not the architecture being linked (i386) 
ld: warning: in /opt/local/lib/libgdk-x11-2.0.dylib, file was built for unsupported file format which is not the architecture being linked (i386) 
ld: warning: in /opt/local/lib/libatk-1.0.dylib, file was built for unsupported file format which is not the architecture being linked (i386) 
ld: warning: in /opt/local/lib/libpangocairo-1.0.dylib, file was built for unsupported file format which is not the architecture being linked (i386) 
.. etc... 

我使用的OS X 10.6.8，酷睿i5的MacBook Pro。

編輯我剛剛發現我正在使用32位haskell平臺，這可能是問題的一部分。但是，我無法安裝64位版本（安裝期間它有一個未指定的錯誤）。我找不到卸載程序。根據this page，我應該在/Library/Frameworks/GHC.framework/Tools/Uninstaller找到一個卸載程序，但沒有任何內容。

它看起來像Macports庫只有64位。您可以使用lipo -info /opt/local/lib/libgtk-x11-2.0.dylib進行確認如果是這種情況，您應該使用+通用變體重新安裝它們，以便連接32位和64位代碼。
