[SOLVED] borked my kde 3.5.7 install and qt errors

[hunky]

I started to emerge -uD world and it started kde-meta-3.5.7. It is failing on kdebase-kdelibs-3.5.7-r2 with this error:

Code: Select all

For more details about this problem, look at the end of config.log.
Make sure that you have compiled Qt with thread support!

I've already done emerge -av1 expat curl XML-Parser gettext.
I've also done the same with qt. I've also tried enabling qt3support.
I had the xeffects overlay in place and the first time I tried to emerge world the kdelibs error said that this was an xeffects build. So I panicked and removed the xeffects overlay from the make.conf file and did a layman -d xeffects. Doing emerge syncs don't help fix the above error I'm now getting.

Revdep-rebuild is broken as well - it dies on the first package it wants to rebuild: kdelibs-3.5.7-r2. It also wants to rebuild all the 3.5.5 kde that is installed. Here's its error:

Code: Select all

Calculating dependencies |
!!! Multiple versions within a single package slot have been
!!! pulled into the dependency graph:

('ebuild', '/', 'kde-base/kdelibs-3.5.6-r10', 'merge') pulled in by
  ('ebuild', '/', 'kde-base/libkdeedu-3.5.4', 'merge')

('ebuild', '/', 'kde-base/kdelibs-3.5.5-r10', 'merge') (no parents)

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in the
dependencies of two different packages, then those packages can not be
installed simultaneously.

I may try unmerging kdelibs-3.5.5 but don't want to totally break the machine - right now if I don't reboot I can still use it for trying to fix this. Help appreciated! cheers, /jd

[edit] hadn't been using the -N in emerge so tried it. Had several packages ahead of kdelibs to install so went ahead. However, it quit on qjackctl with this:

Code: Select all

configure: error: Qt library not found. Maybe QTDIR isn't properly set.

which is different in other errors which are showing some qtdir = /usr/qt/3 on some packages. ?

i had the same exact problem

what i did was first did emerge kde

then it gave me problems with libexpat so i did revdep-rebuild

and then finished with emerge --update --newuse --deep world

thats what i did at least. it works fine now

[hunky]

rgk:

Thanks for the reply but not sure I follow at all. I'm having errors showing problems with qt - I don't think it is libexpat problems yet. Plus, I can't revdep-rebuild. Did you have the error that I show above and if so, on what package? Good to hear it is working for you - hope to get over this hurdle sooner than later. /jd

[intmain]

Code: Select all

...
checking whether QTDIR environment variable is set... /usr/lib/qt4/
checking for main in -lqt-mt... no
checking for main in -lqt... no
configure: error: Qt library not found. Maybe QTDIR isn't properly set.
...

Obviously QTDIR is not set correctly because it points to /usr/lib/qt4 but Qt4 does not use the QTDIR variable, it must point to the Qt3 directory which is /usr/qt/3. Try export QTDIR="/usr/qt/3".

[didymos]

I would suspect that with QTDIR set to /usr/lib/qt4/ , Qt3 isn't even installed, but it obviously is. Have you tried to just re-emerge Qt3 yet?

As to the revdep-rebuild issue, if you're still getting that, unmerge libkdeedu-3.5.4, then see if it gets pulled back in. If you're concerned about breakage, just use quickpkg to back it up (this would apply to kdelibs as well). What I'm wondering is how you managed to get kdelibs-3.5.7-r2 and kdelibs-3.5.5 both on the system at once.

[edit] The ironic thing is, that would be the correct setting for qjackctl-0.3.1a, which has to link with Qt4.

[hilde]

This looks like the same problem as http://forums.gentoo.org/viewtopic-t-57 ... elibs.html.
I first re-emerged fontconfig and then qt3. Now kdelibs seems to be compiling successfully. After installing the new kde, you'll have to do revdep-rebuild anyway, so every other program which uses expat will be recompiled.

[hunky]

Sweet! I wake up in the morning and there's some great replies here to help with my problem. Thanks!

So I re-emerged both fontconfig and qt-3.3.8-r3 (fontconfig first otherwise qt fails) and then with emerge --resume , kdelibs compiled and I'm on my way. Both fonconfig and qt3 were installed but apparently needed re-emerged.

didymos: I didn't have kdelibs-3.5.7 installed yet as it wouldn't emerge. I don't know enough about revdep-rebuild to know why it wanted to rebuild it other than I must have emerged a few programs before kdelibs when updating that wanted it? I'll have to play around with re-emerging qjackctl and see what happens when the main kde update is done.

I'll mark this solved if successful on completeing the upgrade.

Next step will probably be getting compiz-fusion running since I'm sure I've killed my beryl setup, of which I've grown quite fond.
