Hello Gentoo-experts.

Yesterday I updated some qt-ebuilds:

Now all kde4 applications like juk or kmail have an old windows style, not the breeze theme anymore. It seems to be the qt4 default theme.
I tried to set it in Plasma-desktop again, reemerge kdelibs, no luck.

Any ideas, a place to look?
Thank you for your help.

Did you complete the upgrade to GCC 5.4.0 according to the news item?

I did an "revdep-rebuild --library 'libstdc++.so.6' -- --exclude gcc" and an emerge -ea --oneshot @world (tradition and an core i7...). That's why a "Expected build key "x86_64 linux g++-4 full-config", got "x86_64 linux g++-5.4.0" irritates me.

I now put following into ma package.mask
Code:
#PRIVATE kmail/kde4 fail
=dev-qt/qtcore-4.8.7-r2
=dev-qt/qttranslations-4.8.7
=dev-qt/qtscript-4.8.7
=dev-qt/qtgui-4.8.7
=dev-qt/qtdbus-4.8.7
=dev-qt/qtsvg-4.8.7
=dev-qt/qtopengl-4.8.7
=dev-qt/qtxmlpatterns-4.8.7
=dev-qt/qttest-4.8.7
=dev-qt/qtwebkit-4.8.7
=dev-qt/qtmultimedia-4.8.7
=dev-qt/qtsql-4.8.7
=dev-qt/qt3support-4.8.7
=dev-qt/qtdeclarative-4.8.7
=dev-qt/designer-4.8.7
reemerged, and kontact works normal again?!?
(emails listened, todolist here, adressbook...)

I know what a compiler-switch can do (using gentoo since gentoo 1.4). but then a downgrade shouldn't work?
Or is it more likely that an revdep-rebuild and an emerge -e just overlook qt4 because of qt5-packages with the same name?
Having only gcc 5.4 for some time now why does an upgrade of qt4 (which compiles with gcc 5.4 too, what else?) break binary compatibility?
Why does an downgrade with 5.4 solves this binary compatibility?
I'll test this, # my .mask-entries again, be back in some minutes.

For me kmail lost the ability to configure imap which came from the latest kde-apps upgrade. There's upstream bugs reported on the matter and there's a fix been pushed out. Something about an "include" file not being there. So I assume that will be pushed put in the portage tree.

I have upgraded my gcc and rebuilt the system as the eselect news informed to do.


However the latest QT upgrades broke like you say, breeze theme on kde4 apps as well as amarok ability to play audio.

This is not a theme problem - all KDE4 programs lost access to their settings completely. Amarok starts the first-run assistant, for example. Re-emerging Qt 4.8.6 now, after masking 4.8.7...

upgrade to qt-4.8.7 and all problemes (theme, lost akonadi-resources...) are here again.
So another emerge -e would make no sense?

Thanks for all your helpof you all. I'll stick with qt 4.8.6 at now.
Can you link the upstream-bugs here? Might be good to know for bugs.gentoo.org or to verify if it is already in the portage-tree.
@astrum You will get the most impact using kdepim. Does this work?

Nevertheless I change my title on the topic in something more useful now.

Try to rebuild everything that links against libQtCore.so.4. In my case that helped:
Code:
revdep-rebuild --library='libQtCore.so.4'

You probably can skip all qt-libs/* packages, as they have already been built against the new version.

mrsteven, you are right:
a revdep-rebuild --library='libQtCore.so.4' -- -a got me 92 packages to rebuild (don't mind about the qt-libs/* as libreoffice was on the train too...) got me a working kmail/k3b/juk... with a qt 4.8.7.

I hope this is not needed on every new qt version and slips through revdep-rebuild/preserve-libs.

Thank you for the help!

seems to recompile just kde-apps/kdepim-runtime was sufficient for me.
(I compiled kde-apps/akonadi and kde-apps/kalarm too but not sure it was necessary)

It's the last Qt4 release you will ever install.

I hope so, just one qt-version would be nice.
