lookup_widget() returns a GtkWidget* and you're assigning it to a
GtkNotebook*, a pointer to a different type, which is why the compiler
may complain.
You can do:
notebook=GTK_NOTEBOOK (lookup_widget(GTK_WIDGET(main_window),
"notebook"));
or simply:
notebook= (GtkNotebook*)(lookup_widget(GTK_WIDGET(main_window),
"notebook"));
I think that will fix it.
