No problem. Keep asking.

Yes. I thought that you might need some similar fixes in there. But please
see my suggestions below, after the compile errors.

I would also like you to try gtkmm 2.0.2, because this is the last version
that I know to work with the SUN compiler. Please tell me if you see the
same compile error.

You have a newer version of the compiler, and it is possible that it has new
problems. gtkmm 1.3.26 had some extra workarounds that were needed before
the SUN compiler was fixed. You might try that version as well, to give us
some information.

These bugzilla queries (searches for "SUN") might also be interesting:

The .h and .cc files are generally generated, from the .hg and .ccg files,
but please hack about with the .h and .cc files so we can see what code the
.hg and .ccg files should be generating.

So, the error starts in pango/pangomm/context.cc, on this line I think:

Glib::ArrayHandle< Glib::RefPtr<FontFamily> > Context::list_families() const
{
  ..
}

This code looks the same in gtkmm 2.0.2, by the way.

I'm not sure what the compiler is complaining about, but I suggest that you
try:
- Specifying the Traits, instead of depending on the default template
parameter.
  You might use a typedef to make that easier. For instance:

  typedef Glib::Container_Helpers::TypeTraits<
Glib::RefPtr<Pango::FontFamily> > testtraitstype;
  typedef Glib::ArrayHandle< Glib::RefPtr<FontFamily>, testtraitstype>
testhandletype;

  See glib/glibmm/arrayhandle.h: 184 for more information about that
template.

- #ifdefing that method out, so we can concentrate on the other ones.

But there seems to be some interaction of FontFamily and FontFace - both are
mentioned in the error, but I'm not sure why.

Basically, I think something somewhere should specify a template paramter
instead of hoping that the compiler knows which specialization to use. That
might be a method somewhere, or a class - you can call
something.somemethod<TheClass>(), for instance.

Keep reading, please:

The 2 "ambiguou" methods mentioned there seem to be identical:
  Glib::unwrap<const Gdk::Drawable>(const Glib::RefPtr<const
Gdk::Drawable>&)
  Glib::unwrap<const Gdk::Drawable>(const Glib::RefPtr<const
Gdk::Drawable>&)
which is strange. But Drawable has some strange typedefs - please try using
window.gobj() instead of the Glib::unwrap<>(window).

Excellent. We will get there.
