Re: GTK+ library access issue?

[David Buchan <pdbuchan yahoo com>]

Thanks Dave.

I tried pkg-config from the command line and here's what we get:

$ pkg-config --cflags gtk+-2.0 gmodule-2.0
-pthread -I/usr/include/gtk-2.0 -I/usr/lib/i386-linux-gnu/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/pango-1.0 -I/usr/include/gio-unix-2.0/ -I/usr/include/glib-2.0 -I/usr/lib/i386-linux-gnu/glib-2.0/include -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libpng12

$ pkg-config --libs   gtk+-2.0 gmodule-2.0
-pthread -Wl,--export-dynamic -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgio-2.0 -lpangoft2-1.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lcairo -lpango-1.0 -lfreetype -lfontconfig -lgobject-2.0 -lgthread-2.0 -lgmodule-2.0 -lrt -lglib-2.0

Does anybody see anything missing that would cause such basic things as g_free to be missing?

Dave

A typical symptom of empty CFLAGS and LIBS due to a pkg-config error.
Run the pkg-config commands manually and see what they print. Fix the
problems (probably something missing).  I cannot give any Ubuntu-specific
advice but the problem is usually obvious from the pkg-config errors.
