Re: Grandr and libs problems

[Benjamin Fleming <flemingb oit edu>]

This is what I get in my config.log. I tried running
configure and make in the actual grandr dir like Joe did
(garnome-0.27.1/gnome/grandr_applet/work/main.d/grandr_applet-0.2/) and it
configured and compiled w/o a hitch. I am thinking that it has to be a
problem in garnome (maybe a typo in a path variable?)
Anyway, here is my config.log
...
