So, first of all, if I'm not mistaken your use of gtk-config implies
that you are using an ancient version of Gtk+, namely Gtk+ 1.2. Is this
correct? This would then also use an ancient GLib 1.2, which is not
API/ABI compatible with modern GLib/Gtk applications, and you can't use
GStreamer 1.0 (or 0.10 or 0.8) with GLib 1.2, only with GLib 2.0. But I
might be mistaken about all of this of course.

So in any case, make sure to use either Gtk+ 2.x or 3.x which both use
GLib 2.x. Then what should work is:

gcc -Wall foo.c -o foo $(pkg-config --cflags --libs gstreamer-1.0 gtk
+-3.0)

Cheers
