Bug 323687 – dev-python/PyQt4 doesn't build QtWebKit module when asked to

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Andrej Kacian 2010-06-12 15:52:29 UTC]

As seen in attached build log, PyQt4 (I tried versions 4.7.3, 4.7 and 4.6.2) doesn't build a QtWebKit module, even with webkit USE flag enabled, and qt-webkit package installed. I have no idea why. The configure.py script seems to be testing for a working C header file from qt-webkit package, but that file is installed over here.

Have you tried re-emerging qt-webkit?

[Comment 3 Andrej Kacian 2010-06-12 16:41:02 UTC]

I did. There was no change in list of installed files.

Add --verbose inside the myconf variable somewhere near line 88 of PyQt4-4.7.3.ebuild. This way we should understand why the test for QtWebKit fails.

Build log attached, but looks like this is causing it:

/usr/lib/qt4/libphonon.so: undefined reference to `QDataStream::QDataStream(QByteArray*, int)'

I can not remerge x11-libs/qt-phonon, because it wants qt-gui with qt3support USE flag, which I disabled so that I could install app-text/calibre (which fails to emerge, due to missing QtWebKit module from PyQt4).
I hope the above sentence make sense.

Yep, this is the cause.

No, it doesn't. Why do you need x11-libs/qt-gui _without_ qt3support?

[Comment 7 Andrej Kacian 2010-06-12 19:40:26 UTC]

Hm, now I'm not completely sure why. I remember some package requesting specifically that I disable qt3support flag for qt-opengl, so I thought it will be better to have it disabled for whole qt core (qt-core, qt-gui).

Anyway, I remerged qt-gui and qt-core with qt3support, remerged qt-phonon, PyQt4, and now calibre installed fine. This could probably be marked INVALID, unless there is something to improve in the dependencies to prevent this in the future.

Thanks for your time.

PyQt4 dependencies are fine.
Closing as invalid since you were trying to build PyQt4 against a broken libphonon.
