Actually, I'm wrong about the above.  There should be no reason why the
cool button example should not compile for either gtkmm-2.4 or
gtkmm-3.0.  There is a typo in the main.cc file that you're using.  The
line:

Gtk::Main (argc, argv);

Should be:

Gtk::Main kit(argc, argv);

Something minor but it makes the Gtk::Main instance disappear which
causes the errors/warnings you reported.
