using gobject without gtk

[Martin Kalbfuß <ma kalbfuss web de>]

Hi,

I want to use gobject for an extension of the allegro library. Without
touching gtk+.

When I compile my test program. I get

(process:17961): GLib-GObject-CRITICAL
**: /build/buildd-glib2.0_2.22.4-1-i386-jRfNZE/glib2.0-2.22.4/gobject/gtype.c:2458: initialization assertion failed, use IA__g_type_init() prior to this function

(process:17961): GLib-CRITICAL **: g_once_init_leave: assertion
`initialization_value != 0' failed

(process:17961): GLib-GObject-CRITICAL **: g_object_new: assertion
`G_TYPE_IS_OBJECT (object_type)' failed


Google tells me to call gtk_init. And that's the problem. What I have to
do, to initialize it properly?

Thanks.
