Subject: kde-sunset: gtk-engines-qt build failure
Date: Thu, 13 Oct 2011 15:06:06 -0700
I finally got KDE 3.5.10 built and installed, after keywording kdelibs,
kcontrol, gdk-pixbuf, and libpng.  Revdep-rebuild appears to have done
the trick with the upgrade to libpng.

Now I'm trying to install gtk-engines-qt, whose build fails with the
indicated error:

In file included from /usr/include/glib-2.0/gio/gio.h:54:0,
                 from /usr/include/gtk-2.0/gdk/gdkapplaunchcontext.h:30,
                 from /usr/include/gtk-2.0/gdk/gdk.h:32,
                 from /usr/include/gtk-2.0/gdk/gdkprivate.h:30,
                 from /usr/include/gtk-2.0/gdk/gdkx.h:30,
                 from
                 /tmp/portage/x11-themes/gtk-engines-qt-0.8-r4/work/gtk-qt-engine/src/qt_qt_wrapper.cpp:18:
/usr/include/glib-2.0/gio/gdbusintrospection.h: At global scope:
/usr/include/glib-2.0/gio/gdbusintrospection.h:151:25: error: expected
unqualified-id before ‘protected’
/usr/include/glib-2.0/gio/gdbusintrospection.h:151:25: error: expected
‘;’ before ‘protected’

The system glib is 2.28.8 and gtk+ is at 2.24.4 .

I think this may be due to a conflicting use of the keyword "signals"
between Qt and GLib (or gtk).

Nokia (for now) has a guide on what to do about this:

http://www.developer.nokia.com/Community/Wiki/How_to_prevent_symbol_collisions_between_GTK%2B_and_Qt

There are a couple of bug reports along similar lines in the Debian bug
tracker:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=627016
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=614436

kde-sunset devs: could you please address this in a subsequent rev of
the theming engine package?

Thank you very much.
