gdk/gdk.h：没有这样的文件或目录

Question

I am trying to use gui with gkt-2.0 in Linux mint 32bit. When I try to compile gui.c I encountered following error message:

#include<gtk-2.0/gtk/gtk.h>

void main(){
}

In file included from gui.c:1:0:
/usr/include/gtk-2.0/gtk/gtk.h:32:10: fatal error: gdk/gdk.h: No such file or directory
 #include <gdk/gdk.h>
          ^~~~~~~~~~~

Answer 1

When the appropriate packages are installed, you can add the needed include search directories with option -I , and the libraries of course -l , eg

gcc -I/usr/include/gtk-2.0 gui.c -o gui -lgtk-2.0

The source should be changed to

#include <gtk/gtk.h>

To avoid hard-coding any paths and names, you could use pkg-config (Compiling GTK Applications on UNIX)

gcc $(pkg-config --cflags gtk+-3.0) gui.c -o gui $(pkg-config --libs gtk+-3.0)

Better yet, use make or some other build tool.
