qt5 applications broken after updating.

Hi all.

When trying to start any qt5 applications, for example trying texstudio, results in an error:

"Cannot mix incompatible Qt library (version 0x50d02) with this library (version 0x50e01)"

As per the wiki I checked QT_QPA_PLATFORMTHEME and rebuilt qt5ct using yay.

However, the problem still persists.

output of pacman -Q | grep qt5 is :

libdbusmenu-qt5 0.9.3+16.04.20160218-4
phonon-qt5 4.11.1-1
phonon-qt5-gstreamer 4.10.0-1
polkit-qt5 0.113.0-1
poppler-qt5 0.82.0-1
qt5-base 5.14.1-2
qt5-declarative 5.13.2-1
qt5-graphicaleffects 5.14.1-1
qt5-location 5.13.2-2
qt5-multimedia 5.13.2-1
qt5-quickcontrols 5.13.2-1
qt5-quickcontrols2 5.13.2-1
qt5-script 5.13.2-1
qt5-sensors 5.13.2-1
qt5-speech 5.13.2-1
qt5-styleplugins 5.0.0.20170311-19
qt5-svg 5.13.2-1
qt5-webchannel 5.13.2-1
qt5-webkit 5.212.0alpha3-6
qt5-x11extras 5.14.1-1
qt5ct 0.41-2

Any advice to troubleshoot this is greatly appreciated.

Thank you.

Re: qt5 applications broken after updating.

Thanks for the reply. 

I downgraded to the previous version of qt5-base, however now some packages display errors such as (using yakuake as an example...):

yakuake: /usr/lib/libQt5Core.so.5: version `Qt_5.14' not found (required by /usr/lib/libKF5NotifyConfig.so.5)
yakuake: /usr/lib/libQt5Core.so.5: version `Qt_5.14' not found (required by /usr/lib/libKF5WaylandClient.so.5)
yakuake: /usr/lib/libQt5Core.so.5: version `Qt_5.14' not found (required by /usr/lib/libQt5X11Extras.so.5)

any ideas?

Re: qt5 applications broken after updating.

Hi, when I do a pacman -Syyu this doesn't change the 5.13 packages, would you expect the 5.13 packages to be upgraded ?

Re: qt5 applications broken after updating.

https://www.archlinux.org/packages/extr … clarative/
https://www.archlinux.org/packages/extr … /qt5-base/

Both packages are in extra so it is strange for a mirror to have one updated but not the other.

What is the full output from

LC_ALL=C pacman -Syu --debug
