All the above packages can be found at Linux Packages, ready for Slackware 11. During the install, you'll be prompted for some perl modules. You can let the suggested automated process do it for you.

This problem could be caused by the -Wl,--as-needed cflag/ldflag, although Xfce should be save on this
flag.

I'm trying to install xfce4-4.4RC1 on slackware. Here's my specs:

Kernel 2.6.14.2
Gcc 3.4.2
xfce4-4.2.3.2 (already installed)
Glib 2.12.4
gtk+ 2.10.2
pango 2.14.6
cairo 1.2.4
freetype 2.2.1

During the Terminal compile, I get (forgive me for posting all this shit, but hopefully it's useful):

Anybody know what library contains these undefined references? A google search hinted that I might need glib > 2.10, but since I have 2.12.4, could this be what's causing it or is it something else?

Any help is greatly appreciated!!
