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: Select all

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: Select all

 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?

So this one is solved. Had to change some things in qt-core-ebuild:

Code: Select all

    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: Select all

        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?

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

yes, i recompiled kdelibs, and kdm.

Post by **asturm** » Sat Feb 07, 2009 10:03 am

Maybe I'm lucky not having done the latter?

franzf · Post by **franzf** » Sat Feb 07, 2009 10:09 am

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

)

Unfortunatelly, this is a random situation. For me, kdm works with 4.5.9999 and 4.9999 but I many people are having issues with kdm. I cant help ( for now )

Here's a patch to prevent segfaults in kdm. Should apply against latest qt 4.5 snapshot

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

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

Seems to has been fixed upstream: http://websvn.kde.org/?view=rev&revision=922805

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.

does kio_http work properly with rc1? I dont remember what versions I tested, but konqueror and akregator would segfault on me.

Thought I'd mention- k3b,

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).

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.
