使用 Homebrew 安装 C++ 库

Question

我正在尝试为我的项目安装一个 C++ 库 (gtkmm) 并使用一个简单的测试文件（维基百科关于 gtkmm 的主要页面）来测试这个安装。我做了 brew install gtkmm3，它安装了它但是当我用 clang++ -Wall -Werror -Wextra -o test test.cpp 编译时它没有找到我的 header :

test.cpp:15:10: fatal error: 'gtkmm-3.0/gtkmm.h' file not found
#include <gtkmm-3.0/gtkmm.h>

header 位于 ~/homebrew/include/gtkmm-3.0/gtkmm.h。我试过了：

将 $HOME"/homebrew/include" 添加到 $PATH 并在我的源文件中使用 #include <gtkmm-3.0/gtkmm.h>。
将 $HOME"/homebrew/include/gtkmm-3.0" 添加到我的 $PATH 并在我的源文件中使用 #include <gtkmm.h>。

但是还是编译不了

我该怎么办？

是的，像这样使用 pkgconfig 它会告诉你所有的包含路径和你需要的 link 路径：

pkg-config --libs --cflags /usr/local/Cellar/gtkmm3/*/lib/pkgconfig/gdkmm-3.0.pc

输出

然后你可以编译：

clang++ $(pkg-config --libs --cflags /usr/local/Cellar/gtkmm3/*/lib/pkgconfig/gdkmm-3.0.pc) someFile.cpp -o someFile
