【问题描述】：

我尝试在我的 Mac 上安装 gtk haskell。我使用this 站点安装它。但是我在最后一步使用命令失败了：sudo cabal install --with-gcc=gcc-4.8 gtk

最终答案是：

gtk-0.11.1, gtk-0.11.0 (conflict: requires pkg-config package gtk+-2.0-any,
not found in the pkg-config database)
Dependency tree exhaustively searched.

Cabal 应该是最新的。

提前致谢。

编辑： 完成 ErikR 配方后，它开始使用命令 cabal install gtk 进行安装。这是错误消息，我得到了：

【问题讨论】：

你使用的是什么版本的 cabal/ghc
您遵循了在该页面上安装 gtk 的哪些食谱 - 1、2、3、4、5 或 6？你能运行gtk-demo吗？你运行的是什么版本的 OS X？
cabal 版本 1.24.0.0 和 ghc 版本 7.10.3，我尝试了配方 2。和 os x 版本 10.11.6。是的，我可以开始演示了
现在 pkg-config 正在寻找 gtk+-2.0，现在当您尝试 cabal install gtk 时会发生什么？
我今天遇到了完全相同的问题，我设法使用 has-quartz-gtk 标志安装了 gtk：cabal install gtk -f have-quartz-gtk（当然，按照 ErikR 的建议设置了环境变量 PKG_CONFIG_PATH）

标签： macos haskell gcc gtk2hs

【解决方案1】：

问题是pkg-config找不到文件gtk+-2.0.pc：

需要 pkg-config 软件包 gtk+-2.0-any, 在 pkg-config 数据库中找不到

故障排除步骤：

检查哪些目录 pkg-config 配置为查找 .pc 文件：
```
$  pkg-config --variable pc_path pkg-config
```
在我的系统上，gtk+-2.0.pc 位于 /usr/local/lib/pkgconfig。我通过设置PKG_CONFIG_PATH环境变量扩展了搜索路径：
```
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:
```
测试pkg-config能找到gtk+-2.0：
```
pkg-config gtk+-2.0 --exists && echo Found the library
```
没有输出意味着没有找到 .pc 文件。您可以使用的另一个命令检查是：
```
pkg-config gtk+-2.0 --libs --print-errors
```
您将看到一条错误消息或一长串 C 编译器的标志，告诉它如何与 gtk 库链接。
查找 .pc 文件的另一个技巧是使用locate 命令（假设定位数据库已更新）：
```
locate '*.pc' | grep gtk
```

【讨论】：

感谢您的快速解决方案，但它对我不起作用。我更改了 PKG_CONFIG_PATH 的变量，并在下一步中得到了“找到库”的答案。在再次尝试安装失败后，我检查了错误消息（3 的第 2 部分），它给了我很多标志，例如“-L/usr/local/Cellar/gtk+/2.24.29/lib”。如何链接这些标志？
只是说“它不起作用”不是很有帮助。请用您尝试过的内容和错误消息更新您的问题。
根据@eugenk 上面的评论：cabal install gtk -f have-quartz-gtk 为我解决了这个问题。

【解决方案2】：

如果你使用 Homebrew，你可以通过输入以下命令安装 gtk+3：

brew install gtk+3
