Hi all,

I've been having a few problems with a week old gentoo desktop install with
gnome 3 from the gnome overlay. Both libgnomeprint-2.18.8 and
evolution-3.0.3 are failing showing the errors below which I think are
related to pango.

I've looked for bugs etc and rebuild pango but it didn't seem to help. Any
ideas?
First time posting on the list so be gentle!

Thanks all

Oliver

The guilty syntax (appearing in several pango headers) seems to be this:

 G_CONST_RETURN char **start
                ^^^^
Looking at the vast number of uses of G_CONST_RETURN in other header files,
I'm guessing that the word 'char' should really be 'gchar'.

I would test this idea by editing the headers in /usr/include/pango-1.0/pango
by hand, making the above change to every instance of 'C_CONST_RETURN char'.

If that trick works, then it's definitely a bug in the pango package and
needs to be fixed.  Otherwise, I'm stumped.

Managed to sort it, seems that the live glib ebuild dropped support for
G_CONST_RETURN. Downgrading to glib-2.28.8 sorted it but broke some other
packages. Is there an overlay newer than the gnome one? Seems I have some
packages from the newer gnome 3.1 release and some from the 3.0 and they
aren't playing nice.
