I don't see linking your program with libgtkada.a. You probably have some
problem either in the project file or else in the GtkAda installation.

BTW. There is an advanced text editor in Gtk:

http://projects.gnome.org/gtksourceview

on top of the Gtk.Text_View, with an integrated language syntax
highlighting, undo buffer etc.
