gtkmm-3.0：使用 pkg-config 程序构建失败的 Msys2 Netbeans

Question

网络豆：8.2

Windows : 10 个 64 位

MinGW-w64 g++：7.2

我正在尝试使用 gtkmm 3.0 参考 Programming with gtkmm 一书创建一个空的 window。我指的是第 3 章中的 (3.1) 简单示例。基础知识

#include <gtkmm.h>

int main(int argc, char *argv[])
{
  auto app = Gtk::Application::create(argc, argv, "org.gtkmm.examples.base");

  Gtk::Window window;
  window.set_default_size(200, 200);

  return app->run(window);
}

我都试过了

#include <gtkmm-3.0/gtkmm.h>
#include <gtkmm.h>

但是我的构建在这两种情况下都失败了。

g++    -c -g `pkg-config --cflags gtkmm-3.0` -std=c++14  -MMD -MP -MF "build/Debug/MinGW-Windows/main.o.d" -o build/Debug/MinGW-Windows/main.o main.cpp
Package gtkmm-3.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtkmm-3.0.pc'
to the PKG_CONFIG_PATH environment variable

我在E盘安装了msys2。我无法在 C 驱动器中安装 msys2，因为安装卡在了 0%。

我在我的环境变量中添加了 PKG_CONFIG_PATH :- E:\msys64\mingw64\bin。我可以使用 --cflags 查看包含目录，使用 --libs

查看链接库

我在其他机器上遇到了同样的问题，msys2 安装在 C 盘并且安装顺利。

请指教。

分两步解决：

修改 Msys2 shell 中的 $PKG_CONFIG_PATH 以包含包含各个包的 .pc 文件的 pkg_config 文件夹。 eg: export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/mingw64/lib/pkgconfig 或者在/home//.bashrc
创建 PKG_CONFIG_PATH 环境变量，其值为 Linux 类型的路径，即 pkg_config 文件夹的 /mingw64/lib/pkgconfig，其中包含各个包的 .pc 文件。例如：PKG_CONFIG_PATH = /mingw64/lib/pkgconfig
