Question

我正在Windows上进行C开发并安装了Msys2。使用Msys2 pacman，我安装了64位mingw和Glib。我可以使用已安装的gcc进行编译。现在，Glib标头位于C:\msys64\mingw64\include\glib-2.0和C:\msys64\usr\include\glib-2.0。

将#include <gmodule.h>添加到源文件并进行编译时，我得到： fatal error: gmodule.h: No such file or directory

使用gcc -xc -E -v -检查包含路径时看到错误：

如何修复包含路径，以便gcc可以找到GLib标头？我可以将其添加到规范文件或C_INCLUDE_PATH中，但是我绕过了该错误，而不是进行了修复。

如果安装pkg-config，则可以使用它来获取glib的构建标志，如下所示：

$ pkg-config --cflags glib-2.0
-I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include
$ pkg-config --libs glib-2.0       
$ -lglib-2.0

标志因系统而异，但是库名称（glib-2.0）希望是一致的。

Msys2和Mingw64系统包含目录不正确，导致无法使用GLib
