Re: Can't get basic hello world app to compile... help?

Try looking at the output of pkg-config --cflags --libs gtk+-2.0 You
might be missing some dependencies like cairo, pango, etc. (although I
thought the package manager took care of that for you). If you also
want the gnome development libraries, try installing the
gnome-core-devel package.
