Question

基本问题：

我试图在OSX 10.10.4上使用gtk安装Haskell的standard mac instructions软件包。具体来说，我想运行threadscope，因此我需要gtk。 homebrew和gtk buildtools的早期阶段工作正常，但是当我

时

cabal install gtk

或使用

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

我收到以下编译错误：

Graphics/UI/Gtk/Embedding/Plug.chs:120:6:

            with actual type ‘Maybe DrawWindow’

我之前已经安装并运行了Haskell的gtk库和threadscope应用程序，然后我将Haskell平台从ghc 7.8.4更新为ghc 7.10.2。起初我认为存在安装冲突，但是我使用thorough removal instructions反复从系统中删除了Haskell平台，并重新尝试了threadscope安装但没有成功。我甚至使用gtk+删除并重新安装了基础homebrew及相关软件包，但再次没有成功。

我不确定Ptr ()和Maybe DrawWindow类型的来源，以及冲突可能来自哪里。任何可能出错的想法都会受到欢迎！

Answer 1

也许您可以尝试使用此行安装gtk

cabal install gtk -fhave-quartz-gtk

Answer 2

在edsko的博客中有一个安装GTK和threadscope的方法：

在页面中搜索＆＃34; GTK沙箱＆＃34;。

<强>更新

我能够使用ghc-7.10.2上面的说明构建threadcope。

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

沙箱中安装的软件包的特定版本：

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
