For me kdm 4.2.0 does not work with qt 4.5.0-rc1. :?

kdm does not work for me, too.
Crash within QWidgetPrivate::set -> XSetCommand() in libX11 ->strlen() in libc (AFAIR)...

I also have trouble with installing (building works fine) qt-creator (rc and live).
Code:
make[1]: Entering directory `/var/tmp/paludis/dev-util-qt-creator-0.9.2_rc1/work/qt-creator-0.9.2_rc1/src'
cd libs/ && make -f Makefile install
/bin/sh: /usr/bin/qdoc3: No such file or directory

qt-core (4.5.0_rc1) is built with doc enabled, but there is no qdoc executable:
Code:
 paludis --executables qt-core
* x11-libs/qt-core-4.5.0_rc1::installed
    /usr/bin/qmake
    /usr/bin/moc
    /usr/bin/rcc
    /usr/bin/uic

Am i missing something?

Am i missing something?

So this one is solved. Had to change some things in qt-core-ebuild:
Code:
    if use doc; then
        emake INSTALL_ROOT="${D}" install_htmldocs || die "emake install_htmldocs failed."
        dobin "${S}"/tools/qdoc3/qdoc3 || die "dobin qdoc3 failed"
    fi

added the "dobin [...]" in src_install
And added a "/" at the end of "tools/qdoc3" in src_unpack:
Code:
        QT4_TARGET_DIRECTORIES="${QT4_TARGET_DIRECTORIES}
        tools/qdoc3/"

And now also qt-creator finished successfully :)
BTW. the "dobin" in src_install also misses in the stable (4.4.2-r1) qt-core in portage!
Should i open a bugreport, or is some dev reading this thread? :D

Hmmm no problems here with kdm. Did you recompile kdelibs?

I just recompiled kdm as it didn't work...
I did not know there were kdm-related problems, before i stumbled over them by myself.
(But I don't want to give away qt-4.5... It's -- whooo, fast and less glitches :))

Sorry, but no. I have hacked qt code when your overlay first came out to workaround crashes in kdm. No problems so far.

i`ve got several problems with qt 4.5 and kde 4.2

Did you remerge at least kdelibs after upgrading Qt (as suggested by elog message)?


hi. i used qt-4.5 from 4.1.8x to 4.1.96, but i switched back to qt 4.4 with the stable release of 4.2.

in short. yes, i rebuild kdelibs.
--
for 4.2 release of kde, i removed every set from portage and did a depclean, then i build kde 4.2 from scratch including all dependencies. maybe the problem would have been resolved if i did this with qt-4.5 too ...

No problem. Did you posted this patch on kde bugs ( http://bugs.kde.org/ ) ?. If no, please do in order kde devs to verify it and put it on qt-copy :)

Damn, it wasnt a qt-copy error but a kde one. So it qt-4.5 will still fail for those who run ~kde-4.2.0

Me too - I've got message about kdmgreet crash. If I startx, kwin crashes.
Tried re-emerging kdelibs & kdm. Tried version 4.5.9999 with same result.

Well Qt4.5 will be out before kde 4.3 will wont it, so that patch will have to be backported? I dont see why fixes like that wont make it into the main tree if they'll be needed when Qt4.5 goes stable anyway.

Erm, read EXACTLY what the page says ;)
It's a backport-fix from kde-trunk, it is just in the 4.2-branch. So kde-4.2.1 will contain this fix!
It should even be possible, to add this patch to kdm in portage.

yeah, my point was I dont think it'll be a problem for long, as it could be added to kdm-4.2.0-r1 in portage.

For now , you can grab a modified ebuild from my dev space

http://dev.gentoo.org/~hwoarang/kde/kdm


Soon this ebuild will be on tree ( I guess ). Put the two patches on files folder and happy emerging :)

I'm having very good results on three different boxes with qt-4.5-rc1, and kde-live- no problems so far.
Correct me if I'm wrong, but I've always found far less problems using the very latest qt release (rcx's included, but NOT qt-live revisions) and then building kde-live (9999) versions on that.

The other way, i.e. trying to build newer revisions of qt on an earlier kde is far more problematic (even if you rebuild the given kde version afterwards), and for me at least (in compiling time) is not worth the effort.

IMHO, if you are wanting to use qt-live 9999's, then also using kde-live would be almost mandatory to avoid lots of problems, as qt-live is going to be moving past (for example) kde-4.2.0 or any "point" release, almost immediately. In other words, a qt-4.5-rcx is more likely to be OK for a good many kde-live 9999 rebuilds than a kde-4.2.0 release is for the ongoing qt 9999's.

Thought I'd mention- k3b,
Quote:
Version 1.95-svn
Using KDE 4.2.62 (KDE 4.2.62 (KDE 4.3 >= 20090204)
works with qt-4.5-rc1 and kde-live (don't know about any other versions). As a test, I just burnt the newest SystemRescue iso, and k3b worked normally, no problems. First time I've ever been able to get k3b to work with kde4 (any version). :D

One little thing, the cd didn't auto-eject after successfully burning, even though the box to disable eject was not checked by default in settings.

:/, pretty terrible if you ask me, I need qt4.5 for other things that kde (I'm a developer using qt activly), and not having it is unpractical. It wont stop me from using 4.5 ofc, I'll just kill off whatever plasmoids doesn't work, but it still sucks.
