它似乎与最近的cabal版本有关,因为之前曾经工作过.这似乎是一个已知的bug(http://trac.haskell.org/gtk2hs/ticket/1292,http://trac.haskell.org/gtk2hs/ticket/1291和http://trac.haskell.org/ gtk2hs/ticket/1289),但它已经移动数周了.我没有足够的能力建议一个好的解决方案,所以我希望你的建议.这非常烦人,因为我被困在这个重要的项目上,我很难想到我们语言的主要GUI库已经被打破了好几个星期了.

使用Cabal库/ ghc 7.4.1的1.18.1.1版本的cabal-install版本1.18.0.2

谢谢你的帮助

目前正确的解决方案是从 darcs 构建。安装说明的获取最新和最好的部分给出了详细说明；简短的版本是：

darcs get --lazy http://code.haskell.org/gtk2hs
cd gtk2hs
sh bootstrap.sh

编辑： 2013 年 12 月开始的 gtk2hs 官方 0.12.5 版本支持 cabal 1.18，因此不再需要上述 darcs 指令。完整的安装说明仍然可以从Gtk2Hs 下载页面获取；简短的版本是：

cabal install gtk2hs-buildtools
cabal install gtk gtk3
