GTK 2.0 Linker Error in Dev C++ - windows

Question

So I found some tutorials on how to configure gtk to dev c++. I followed that tutorial very closely but when i tried to run this:
#include <gtk/gtk.h>
static void hello( GtkWidget *widget,
gpointer data )
{
g_print ("Hello World\n");
}
static gboolean delete_event( GtkWidget *widget,
GdkEvent *event,
gpointer data )
{
g_print ("delete event occurred\n");
return TRUE;
}
static void destroy( GtkWidget *widget,
gpointer data )
{
gtk_main_quit ();
}
int main( int argc,
char *argv[] )
{
GtkWidget *window;
GtkWidget *button;
gtk_init (&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
g_signal_connect (window, "delete-event",
G_CALLBACK (delete_event), NULL);
g_signal_connect (window, "destroy",
G_CALLBACK (destroy), NULL);
gtk_container_set_border_width (GTK_CONTAINER (window), 10);
button = gtk_button_new_with_label ("Hello World");
g_signal_connect (button, "clicked",
G_CALLBACK (hello), NULL);
g_signal_connect_swapped (button, "clicked",
G_CALLBACK (gtk_widget_destroy),
window);
gtk_container_add (GTK_CONTAINER (window), button);
gtk_widget_show (button);
gtk_widget_show (window);
gtk_main ();
return 0;
}
It produces linker error like this:
[Linker error] undefined reference to g_print
And many more of this type.
How can I fix this?
