This is very probably because of the minimalist USE flags i'm using. Some web application requires PyQt. This web server does not use dbus, X or gui, and those USE flags eliminates a lot of dependencies: [ebuild N ] dev-python/PyQt4-4.7 USE="-X -assistant -dbus -debug -doc -examples -kde -multimedia

as a side note, if i remove " -lXext -lX11 " from the link step, it links ok. I dont know if this is PyQt or gentoo ebuild that forces those uneeded linking flags.
I'm not 100% sure, but that reminds me of something I've read in recent release notes of Qt about qmake. What's your version of qt ?
See http://qt.nokia.com/developer/changes/changes-4.6.0 at "qmake no longer adds Qt internal dependencies". Could this be your problem ?
i use qt-4.6.1 (the current on in ~amd64). The problem i have with PyQt seems to be the opposite of the one mentionned on the qt announce you mentionned : they say qmake no longer add those, and my problem is that the X11 libs are (wrongly) there. % qmake --version QMake version 2.01a Using Qt version 4.6.1 in /usr/lib64/qt4
PyQt4 uses the sip build system, therefore qmake's behaviour is irrelevant.
Thomas, please post the output of: python -c 'import sipconfig; print sipconfig._default_macros["LIBS_X11"]'
I'm quite sure the culprit is the value of LIBS_X11, which is injected in the LIBS variable of every Makefile generated by the sipconfig module. LIBS_X11 is obtained from a platform-specific spec file, more precisely from the value of QMAKE_LIBS_X11, which is parsed by siputils.parse_build_macros() during sip configuration. So the bug is in dev-python/sip rather than PyQt4. A proper fix for this issue does not look easy. I suggest reporting it to upstream and see what they think. On the other hand, the Qt configure script always requires libX11 and libXext, even when building QtCore (it's been patched in Gentoo to skip those checks), thus they might just ignore the problem because it's an unsupported configuration.

The above output confirms my thesis.
Thomas, could you report this issue to the PyQt4 mailing list please?
done. I could not find a bugtracker (which is the usual place to report bug, not lists)

Any news? I can't find your mail in PyQt archives...
i can't find it neither... i dont know why. I've checked my sentbox, the email address is right, and i haven't received any 'error mail'.. so i dont know :-(
You must be subscribed to the ML in order to make posts...
mm.. and my mail gest lost in the void ? Weird.. usually you get at least an email telling you that your post was discarded and why. Anyway, I'm not able to subscribe to yet another mailing list, sorry for this. I will understand if you just close the bug as 'wontfix', or 'upstream'.
Don't worry. I asked Phil (upstream dev) to take a look at this bug.
Fixed in SIP's hg repo: http://www.riverbankcomputing.com/hg/sip/rev/9fe1eb5bf1ac
it belongs to the 4.10 branch, so it should be included in the next release, dev-python/sip-4.10.2
4.10.2 is on tree This bug may close now Reopen if needed
i confirm, dev-python/PyQt4-4.7.3 USE="svg -X -assistant -dbus -debug -doc -examples -kde -multimedia -opengl -phonon -sql -webkit -xmlpatterns" emerges fine. Thanks!
