Description Alex Buell 2010-04-27 16:49:00 UTC

I have -qt -qt3 -qt4 -qt3support -kde use flags enabled as I don't want to use KDE. Unfortunately googleearth needs some qt libraries. This was fine by me until googleearth 5.1.3533.1731 was released in portage yesterday. Turns out this packatge needs qt-phonon but qt-phonon needs +qt3support enabled. Why?

Reproducible: Always

I don't quite remember the history of this package.

Try the following

emerge --nodeps -1 qt-phonon and let me know if it works for you . This will ommit the unsatisfied dependencies ( such as x11-libs/qt-gui[qt3support] ) and will try to build the package

Comment 2 Alex Buell 2010-05-01 11:29:40 UTC

As I'd already removed the googleearth package, I'm trying a variation of this:

emerge --nodeps qt-phonon qt-webkit googlearth

I'll let you know how it gets on with that.

I guess it does need qt3support after all. Why not see if there's a newer version of qt-phonon that's been rewritten not to need qt3support libs?

This is the same issue as in bug #234647 where it was noted that qt3support is needed. It can be seen in http://doc.trolltech.com/4.6/qdatastream-qt3.html that QDataStream(QByteArray*, int) is part of Qt3Support. So it is up to upstream to "fix" this. But as Phonon originates from KDE, which heavily uses Qt3Support, I would not expect this dependency to be dropped anytime soon.
