Why can I not compile GTK+ using MinGW?

Question

Help me Stackoverflow!

So, I feel that I have set up my environment correctly but I cannot build my program!

#include <cstdlib>
#include <stdio.h>
#include <stdlib.h>
#include <gtk/gtk.h>

using namespace std;

/*
* simple gtk application
* author jan bodnar
* date february 17, 2008
*/

int main(int argc, char** argv) {

GtkWidget *window;
gtk_init(&argc, &argv);

window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
gtk_window_set_default_size(GTK_WINDOW(window), 200, 100);
gtk_window_set_title(GTK_WINDOW(window), "gtkapp");
gtk_widget_show(window);

g_signal_connect(window, "destroy",
  G_CALLBACK (gtk_main_quit), NULL);

gtk_main();

return (EXIT_SUCCESS);
}

I generated my list of include dirs from this command: pkg-config --cflags gtk+-2.0

Then I added the include files in the C++ compiler settings in netbeans...

My include directories:

../gtk/include/gtk-2.0
../gtk/lib/gtk-2.0/include
../gtk/include/atk-1.0
../gtk/include/cairo
../gtk/include/pango-1.0
../gtk/include/glib-2.0
../gtk/lib/glib-2.0/include
../gtk/include/libpng12

Then I generated a list of libs from this command: pkg-config --libs gtk+-2.0

Then added my libs to the linker command line in netbeans with this:

-LC:/tools/gtk/lib -lgtk-win32-2.0 -lgdk-win32-2.0 -latk-1.0 -lgio-2.0 -lgdk_pixbuf-2.0 -lpangowin32-1.0 -lgdi32 -lpangocairo-1.0 -lpango-1.0 -lcairo -lgobject-2.0 -lgmodule-2.0 -lglib-2.0 -lintl

But still I cannot compile a simple program! I must be missing something stupid, but I cannot for the life of me figure it out.

Your program compiles, but it does not link. The problem is that, as you have to include all directories for including all headers, you must also indicate the directories for the libraries as well. To summarize: the problem is that netbeans is unable to find the libraries to link.

In your project, go to Properties, Link, and in "Additional Library directories", you will have to mention all directories that include libraries in the Gtkmm distribution.

Hope this helps.
