I have the same problem here. Is there any solution or use flag that should be removed?

Well, I found out that the qt3support USE flag must be set for x11-libs/qt-core since qt-multimedia enables qt3 support in the configuration phase.
hmmm, and does it compile in that case?
It would be highly desirable to get Qt4 cleanly building with "-qt3support" because nothing in Qt4 itself requires it (I routinely build it from tarballs without qt3 support for development purposes)
Yes, it compiles in this case.
Hmmm. Still something tricky I think. cmake build fails not finding QObject aso... Since I already have Qt installed on my Mac, I'll try putting Qt and cmake in packages.provided Do you know it this works?
(In reply to comment #6) > cmake build fails not finding QObject aso... That's strange - cmake does not require Qt for building, unless you need GUI
I'm sorry this is no longer current any more now.
