Hello, When building GTK+ 3.4 for last GTKAda on MacOS by myself, I've got many errors like: GISCAN Gdk-3.0.gir Couldn't find include 'GdkPixbuf-2.0.gir' They are related to gobject-introspection module which seems to be optional in GTK+. Is it really mandatory for GTKAda? Thanks for help, Pascal. http://blady.pagesperso-orange.fr
