基本问题：

我正在尝试使用OSX 10.10.4 上的标准 mac 指令gtk安装 Haskell 的软件包。具体来说，我想运行，所以我需要. 早期阶段和工作都很好，但是当我threadscopegtkhomebrewgtk buildtools

cabal install gtk

或使用

cabal install --with-gcc=gcc-4.8 gtk

我收到以下编译错误：

在我将Haskellgtk平台threadscope从. 起初我假设安装冲突，但我反复使用彻底的删除说明从我的系统中删除了 Haskell 平台，并重新尝试安装，但没有成功。我什至使用 删除并重新安装了底层和相关软件包，但还是没有成功。ghc 7.8.4ghc 7.10.2threadscopegtk+homebrew

我不确定类型Ptr ()和Maybe DrawWindow起源，因此不确定冲突可能来自哪里。欢迎任何关于可能出错的想法！

在 edsko 的博客上有一个安装 GTK 和 threadscope 的方法：

http://www.edsko.net/2015/03/09/sandboxes-revisited/

在页面中搜索“GTK 沙盒”。

更新

我能够使用 ghc-7.10.2 的上述说明构建线程范围。

我使用的具体命令：

export PATH=/opt/X11/lib/pkgconfig
brew install gtk+                      # installed gtk+-2.24.25
brew install poppler                   # installed poppler-0.35.0
cabal sandbox init
cabal install gtk2hs-buildtools
cabal install gtk
cabal install poppler --with-gcc=gcc-4.9 --extra-include-dirs=/usr/local/include
cabal install threadscope

沙箱中安装的包的具体版本：

cairo-0.13.1.0
ghc-events-0.4.4.0
gio-0.13.1.0
glib-0.13.2.1
gtk-0.13.9
hashtables-1.2.0.2
pango-0.13.1.0
poppler-0.13.1
utf8-string-1.0.1.1
