Hi,

compilation of qtwidgets failed.
Is there a dependency currently missing in the ebuild?

Nope. Broken code from upstream. The usual thinking: "nobody will
compile stuff without dbus". But I do. And you seem to as well. I
guess it's actually dev-qt/qtgui with "-dbus" useflag.

[..]

There's some #ifdefs lacking around that stuff, as the code where
e.g. 'QGnomeTheme::createPlatformMenuBar' is implemented, is inside
#ifndef QT_NO_DBUS.

Easy way out if you're not depend on gtk-themes in Qt:

    USE="-gtk" emerge dev-qt/qtwidgets

(and/or put that useflag in /etc/portage/package.use)

Actually, 5.6.2 had a 'gtkstyle' useflag and no "*gtk*" is in
the 5.7.1.ebuild.

Also, it'll probably work if you reemerge dev-qt/qtgui with "dbus"
useflag.

Hi,

Thanks for testing 5.9.2, it's definitely appreciated. I'm sorry you ran
into a build failure.

Please consider filing a bug at https://bugs.gentoo.org/ with emerge
--info and the full build log attached. That way, we can track the issue
better and ensure it doesn't get forgotten.

Kind regards,
