[François-Xavier Houard <idefx Iname com>]

Hi.
I'm trying to compile something with gtkmm, amd whatever I try to
compile (glade empty project, hello world or such), I get this error:
(in fact, I get it anytime I use #include <gtkmm.h>

I use an unstable debian, up to date (from the day).

Can anyone help me and tell me what to do ??

Thank you very much
