Okay, driving me bonkers.
Trying to install MPlayer from source, and everything is fine, except th GUI. IT says it cannot find gtk-config (I am running GTK+ 2.2 which installed fine). It is also looking for this mysterious glib-config. Neither of these I can find on my system using either locate or find (both as root). I have run ldconfig, and updated it for gtk2. A few other programs have also had this gtk-config problem. From what I've read, GTK+2 doesn't use this anymore as it uses pkg-config.
Is there a way to spoof MPlayer into thinking that I actually have these things? ITs driving me nuts. I looked around for the -devel packages, but I don;t know if those would help.

To summarise: nothing can find gtk-config or glib-config.

Well this advice applies to RedHat 8.0 but I'm sure you could figure out the package you need for your distro,

gtk-config and glib-config are part of the gtk+-devel and the glib-devel packages. You can get them from here if you're using RH 8.0

Hope this helps a bit

Those are needed for GTK1, not GTK2

and of course, Gtk is *NOT* Gtk2. They are seperate libraries, and will hapily coexist side by side. MPlayer gui uses Gtk still.
