------- Comment #6 from Tim Mooney  2007-01-12 17:34 UTC -------
Thanks for making the patch Marko.

Unfortunately, still no joy:

"printoperation.cc", line 91: Error: Overloading ambiguity between
"Glib::unwrap<const Gtk::PageSetup>(const Glib::RefPtr<const Gtk::PageSetup>&)"
and "Glib::unwrap<const Gtk::PageSetup>(const Glib::RefPtr<const
Gtk::PageSetup>&)".
"printoperation.cc", line 94: Error: Overloading ambiguity between
"Glib::unwrap<const Gtk::PrintSettings>(const Glib::RefPtr<const
Gtk::PrintSettings>&)" and "Glib::unwrap<const Gtk::PrintSettings>(const
Glib::RefPtr<const Gtk::PrintSettings>&)".
"printoperation.cc", line 115: Error: Overloading ambiguity between
"Glib::unwrap<const Gtk::PageSetup>(const Glib::RefPtr<const Gtk::PageSetup>&)"
and "Glib::unwrap<const Gtk::PageSetup>(const Glib::RefPtr<const
Gtk::PageSetup>&)".
"printoperation.cc", line 118: Error: Overloading ambiguity between
"Glib::unwrap<const Gtk::PrintSettings>(const Glib::RefPtr<const
Gtk::PrintSettings>&)" and "Glib::unwrap<const Gtk::PrintSettings>(const
Glib::RefPtr<const Gtk::PrintSettings>&)".


I have regenerated printoperation.cc, and it includes Marko's second patch.
Line 91 is the last line I show:


  // Specify the exact type with template specialization, to avoid possible
  // ambiguities between the const and non-const versions of unwrap reported
  // by some compilers:
  const GtkPageSetup* c_page_setup =
    Glib::unwrap<const PageSetup>(page_setup);

------- Comment #7 from Marko Anastasov  2007-01-12 20:11 UTC -------
Created an attachment (id=80136)
 --> (http://bugzilla.gnome.org/attachment.cgi?id=80136&action=view)
third attempt

Ok, try with this one. I kinda don't like it, but maybe it'll solve the
problem. Here, the idea is to do eg:

Glib::RefPtr<PageSetup> page_setup_unconst =
    Glib::RefPtr<PageSetup>::cast_const(page_setup);

and then use that new one with unwrap().
