Your GTK+ is 2 stable releases newer than your gtkmm. You are likely to
see this kind of problem when they are not in sync.

The C API changed slightly:
https://git.gnome.org/browse/gtk
+/commit/?id=4b42526e1f33b0ceb9231cee5e15861b97c05726

I could probably track down how we fixed the build for this change in
gtkmm, but it would be hard to apply it to a tarball. You should just
update your gtkmm version. But building from source is always going to
be difficult.
