Question

我尝试在我的mac上安装gtk haskell。我使用this网站来安装它。但是我在命令的最后一步失败了：Resolving dependencies... cabal: Could not resolve dependencies: next goal: gtk (user goal) rejecting: gtk-0.14.5, gtk-0.14.4, gtk-0.14.3, gtk-0.14.2, gtk-0.13.9, gtk-0.13.8.1, gtk-0.13.8, gtk-0.13.7, gtk-0.13.6, gtk-0.13.4, gtk-0.13.3, gtk-0.13.2, gtk-0.13.1, gtk-0.13.0.3, gtk-0.13.0.2, gtk-0.13.0.1, gtk-0.13.0.0, gtk-0.12.5.7, gtk-0.12.5.6, gtk-0.12.5.5, gtk-0.12.5.4, gtk-0.12.5.3, gtk-0.12.5.2, gtk-0.12.5.1, gtk-0.12.5.0, gtk-0.12.4, gtk-0.12.3.1, gtk-0.12.3, gtk-0.12.2, gtk-0.12.1, gtk-0.12.0, gtk-0.11.2, 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.

终端答案是：

cabal install gtk

Cabal应该是最新的。

提前致谢。

Answer 1

问题是pkg-config无法找到文件gtk+-2.0.pc：

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

麻烦的步骤：

检查哪些目录pkg-config配置为查找.pc个文件：
```
$  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环境变量来扩展搜索路径：
```
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:
```
测试pkg-config可以找到gtk + -2.0：
```
pkg-config gtk+-2.0 --exists && echo Found the library
```
没有输出表示找不到.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C编译器的错误消息或一长串标志，告诉它如何链接gtk库。
查找.pc文件的另一个技巧是使用locate命令（假设locate数据库已更新）：
```
locate '*.pc' | grep gtk
```

如果您使用的是Homebrew，则可以输入以下命令来安装gtk + 3：

brew install gtk+3

尝试在mac缺少依赖项上安装gtk
