Msys2和Mingw64系統包含目錄不正確，阻止了GLib的使用

Question

我正在Windows上進行C開發並安裝了Msys2。 使用Msys2 pacman我安裝了64位mingw和Glib。 我可以使用已安裝的gcc進行編譯。 Glib標頭現在位於C:\\msys64\\mingw64\\include\\glib-2.0和C:\\msys64\\usr\\include\\glib-2.0 。

將#include <gmodule.h>添加到源文件並進行編譯時，我得到： fatal error: gmodule.h: No such file or directory

使用gcc -xc -E -v -檢查包含路徑gcc -xc -E -v -我看到錯誤：

如何修復包含路徑，以便gcc可以找到GLib標頭？ 我可以將其添加到規范文件或C_INCLUDE_PATH但是我繞過了該錯誤而不是對其進行了修復。

Answer 1

如果安裝pkg-config ，則可以使用它來獲取glib的構建標志，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

這些標志因系統而異，但是庫名（ glib-2.0 ）希望是一致的。
