Also x11-libs/qt-webkit-4.8.0_rc1 fails.

[Comment 5 VoofT 2011-10-17 13:19:17 UTC]

Confirm fail for 4.8.0_rc1
It seems Apple removed Phonon support at all http://trac.webkit.org/changeset/89832/trunk/Source/WebCore/platform/graphics/MediaPlayer.cpp

[Comment 6 Tommi Asp 2011-10-17 16:37:41 UTC]

Had same problem.
Got it to compile by adding 
"-no-phonon -no-phonon-backend -no-multimedia -no-audio-backend"
to ebuilds myconf, but could be it is only phonon related.

[Comment 7 Stefan Böhmann 2011-10-18 10:04:25 UTC]

Thank you for the Phonon/Multimedia pointer. I've just tried it with "-no-phonon -no-phonon-backend" but had no luck. I'll try again now with your settings ("-no-phonon -no-phonon-backend -no-multimedia -no-audio-backend").

[Comment 8 Stefan Böhmann 2011-10-18 12:39:14 UTC]

For me also "-no-phonon -no-phonon-backend -no-multimedia -no-audio-backend" doesn't work.

[Comment 9 VoofT 2011-10-18 17:27:35 UTC]

If we place "#define GST_DISABLE_DEPRECATED" before including MediaPlayerPrivateGStreamer.h it is possible to compile MediaPlayer.cpp.

This define prevents including of libxml/parser.h which is not necessary right here (see comments in gstconfig.h).

But there're some other files that use one of gstreamer's headers.

This was the right hint for me. If I add GST_DISABLE_DEPRECATED to the preprocessor (add -D GST_DISABLE_DEPRECATED to myconf) I can finally compile qt-webkit.

Thank you VoofT!

[Comment 12 VoofT 2011-10-26 18:00:32 UTC]

Also, as i wrote before, it seems, there is no any phonon dependency, so we can simply delete it. But if it is so, there is gstreamer dependency.
Look here: https://bugs.webkit.org/show_bug.cgi?id=63448

[Comment 13 Davide Pesavento 2011-12-31 01:02:27 UTC]

Is this still an issue in 4.8.0 ?

No - the qting-edge 4.8.0 ebuilds works for me.
