Re: Newbie: Compiler err msg with GTK Tutorial hello code

[David Vestal <dk_vestal netzero net>]

With starting with GTK-2.0 gtk-config is not used. You should use
pkg-config, run pkg-config --list-all to show all the packages
maintained by pkg-config then just use `pkg-config <GTK-module> --cflags
--libs`. On my system, the GTK module is gtk+-x11-2.0, just for a tip on
what to look for.
