Arch Linux User Repository

Hi, Just got this message this morning "Cannot mix incompatible Qt library (5.15.1) with this library (5.15.2) Abandon (core dumped)" Can you iterate your package, please ?

Excellent! :)

You are correct jonathon, I apologize for my error. I ran strace (which I should have done before posting) and discovered the issue was with qt5-styleplugins. I recompiled it and all is well.

If the error is telling you that you can't mix library versions then it's a partial upgrade issue.

Birdtray continues to run fine for me without requiring a rebuild.

birdtray crashes with the latest Qt5 update from 5.15.0 to 5.15.1. I tried compiling and then installing both this package and birdtray-git, and both compilations succeeded with no errors, but unfortunately the new Qt5 version isn't pulled in.

birdtray aborts with the following message:
Cannot mix incompatible Qt library (5.15.0) with this library (5.15.1)

So for now I just downgraded Qt5 back to 5.15.0. Here's the downgrade command:
sudo pacman -U /var/cache/pacman/pkg/python-pyqt5-5.15.0-3-x86_64.pkg.tar.zst /var/cache/pacman/pkg/qt5-multimedia-5.15.0-1-x86_64.pkg.tar.zst /var/cache/pacman/pkg/qt5-wayland-5.15.0-1-x86_64.pkg.tar.zst /var/cache/pacman/pkg/qt5-base-5.15.0-5-x86_64.pkg.tar.zst /var/cache/pacman/pkg/qt5-script-5.15.0-1-x86_64.pkg.tar.zst /var/cache/pacman/pkg/qt5-x11extras-5.15.0-1-x86_64.pkg.tar.zst /var/cache/pacman/pkg/qt5-charts-5.15.0-1-x86_64.pkg.tar.zst /var/cache/pacman/pkg/qt5-svg-5.15.0-1-x86_64.pkg.tar.zst /var/cache/pacman/pkg/qt5-declarative-5.15.0-2-x86_64.pkg.tar.zst /var/cache/pacman/pkg/qt5-tools-5.15.0-3-x86_64.pkg.tar.zst

patch for Qt 15.5 until next birdtray release

@malcolm Same problem for me, I suspect it's because Qt 5.15. I opened a bug report upstream:

https://github.com/gyunaev/birdtray/issues/381

I can't complete the build. Maybe it's because I'm using the beta version of some qt packages?

qt5-translations 5.15.0beta4-1
qt5-tools 5.15.0beta4-1
qt5-x11extras 5.15.0beta4-1
qt5-svg 5.15.0beta4-1

Can you confirm if this is the problem? Here are the logs: https://bin.disroot.org/?e6e801e9d5e031c5#Eo4GyiUsM97pr7nKERg7P9T3dBHS8nf1oABz1edHiu3T

Installing 'qt5-translations' fixed the error message. Thanks. I'll let upstream know.

New optdepend added: qt5-translations.
