Since you are linking gdk-x11, I assume you are building for Linux.

The documentation at
https://developer.gnome.org/gtk3/stable/GtkBuilder.html#gtk-builder-connect-signals
suggests that you should be linking against gmodule-export-2.0, which
is a different thing than gmodule-2.0. And I think the
--export-dynamic needs to be an option in the second gcc command, as
the -Wl,--export-dynamic in the documentation instructs the compiler
to use the export-dynamic option at link time.
