Red Hat Bugzilla – Bug 4952
gtk-config gives incorrect compiler flags
Last modified: 2008-05-01 11:37:51 EDT
Try the following:
# /usr/bin/gtk-config --cflags
The directory /usr/lib/glib/include does not exist in a
fresh install of Red Hat 6.0.
Install the glib-devel package. It is listed as a dependency of the
gtk+-devel package. If you override dependencies, you are on your own.
