【问题描述】：

我想使用 Graphics.UI.Gtk.OpenGL

我有：

OS X 10.11
cabal 版本 1.22.0.0
已安装 gtk

我得到的错误：

Could not find module ‘Graphics.UI.Gtk.OpenGL’
  Perhaps you meant
    Graphics.UI.Gtk.Gdk.GC (from gtk-0.14.2)
    Graphics.UI.Gtk.Cairo (from gtk-0.14.2)
    Graphics.UI.Gtk.Gdk.Gdk (from gtk-0.14.2)
  Use -v to see a list of the files searched for.`

我正在尝试使用以下方式安装 gtkglext：

cabal install gtkglext

然后我得到：

cabal: Error: some packages failed to install:
gio-0.12.5.3 depends on glib-0.12.5.4 which failed to install.
glib-0.12.5.4 failed during the building phase. The exception was:

gtkglext-0.12.5.0 depends on glib-0.12.5.4 which failed to install.
pango-0.12.5.3 depends on glib-0.12.5.4 which failed to install.`

所以我发现，gtkglext 有依赖 glib (>=0.12.5.0 &&

编辑：------------------------------ -------------------------

安装

cabal install gtkglext  --with-gcc=gcc-4.8

产生另一个错误，即：

Graphics/UI/Gtk/General/Structs.hsc:660:3: Couldn't match type ‘CInt’ with ‘Ptr a0’ Expected type: IO (Ptr a0) Actual type: IO CInt In the second argument of ‘($)’, namely ‘(\ (Drawable drawable) -> withForeignPtr drawable gdk_x11_drawable_get_xid) (toDrawable d)’ In the expression: liftM toNativeWindowId $ (\ (Drawable drawable) -> withForeignPtr drawable gdk_x11_drawable_get_xid) (toDrawable d)

谷歌搜索很少会产生： https://github.com/gtk2hs/gtk2hs/issues/27

但我不知道他是如何“完全禁用 drawableGetID 并且这似乎工作正常”。

任何帮助都会很有用。

【问题讨论】：

gtkglext on Hackage 最后一次上传是在 2013 年，所以它可能已经过时了。您可以尝试仅编辑 cabal 文件并删除有问题的边界限制并查看它是否有效。

【解决方案1】：

关键是这个错误信息：

/usr/include/dirent.h:150: (column 10) [FATAL] >>> Syntax error! The symbol `^' does not fit here.

在 github 上搜索该消息会导致他的问题：

https://github.com/gtk2hs/gtk2hs/issues/1

建议的解决方法是使用以下命令运行 cabal：

cabal install --with-gcc=gcc-4.8

所以 - 如果需要，可以升级您的 gcc 版本并使用 --with-gcc= 标志。
