Question

我正在开始一个有希望使用gtk2hs的新项目。但是，我无法在我相当典型的Linux机器上安装此软件包。这是失败：

它似乎与最近的cabal版本有关，因为以前曾经工作过。它似乎是一个已知的错误（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。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。这是非常烦人的，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。

cabal-install version 1.18.0.2使用Cabal库的版本1.18.1.1 / ghc 7.4.1

感谢您的帮助

Answer 1

现在正确的解决方案是从darcs构建。详细说明在安装说明的Getting the latest and greatest部分中给出;简短版本是：

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

编辑： 2013年12月gtk2hs的官方0.12.5版本支持cabal 1.18，因此不再需要上述darcs指令。完整的安装说明仍可从Gtk2Hs download page获得;简短版本是：

cabal install gtk2hs-buildtools
cabal install gtk gtk3

Answer 2

您可以使用Cabal尝试较旧的cabal install --cabal-lib-version=1.16.0 gtk版本。

GTK2HS无法安装最近的cabal版本
