GLIB and GTK
 

i have a rh9 2.4.20-8 kept up-to-date by yum thru Fedora Legacy project., with only a few
non-standard add-ons (alsa sound, winmodem driver, java runtime, jinchess) recently
was trying to install a downloaded game (gnu backgammon) and got error msg:

fall back

*** You must have installed Glib1 or Glib2 in order to

using (rpm -qa |grep -i <...>) i found found packages gtk+-1.2.10-25, glib-1.2.10-10,
glib2-2.2.1-1

my question is: what are GTK+, GLIB, and Glib1 and Glib2 in relation to what i already
have and do i have to install them? thanks for input:

You probably need their development packages., which I think are glib2-devel and gtk-devel, in your case also, you need version 1.2x coz there is also gtk2 & glib2 which are incompatible with their 1.x versions.
