gnox · 2016-12-18 01:17:39

After the latest update of qt5.7.1 , I received this error with qtcreator also qbittorrent .

Cannot mix incompatible Qt library (version 0x50700) with this library (version 0x50701)

I think ok maybe the apps are still not updated with the new version, have to wait for another update .

But if I recompile qbittorrent-git (from AUR) in theory should use the new lib version, but I still receive the same error :

nevermind had to recompile qt5-styleplugins .

eschwartz · 2016-12-18 02:10:05

That error should only happen for software which uses Qt private headers, FWIW. I am pretty sure qbittorrent doesn't use private headers, OTOH style/theme plugins almost definitely do!

I have had the same problem with any Qt5 application.

The solution for me was to recompile the AUR package qt5gtk2.

FWIW, I bumped the pkgrel on that to make sure people rebuild it. I would have done so earlier, but I overlooked qt5-* being moved to [extra] since I recently started using [testing].
