Hi,
has anybody tried to add a recent Qt, e.g. https://download.opensuse.org/repositories/KDE:/Qt5/ to a Leap 15.3 installation using LXQt as DE?
My best guess is it will break LXQt.... Ideally I would like to avoid cloning the LXQt project in order to compile it against qt 5.15.x, if there are other options to achieve this - most welcome!
In theory Qt 5.15.x should be binary compatible with whichever version of Qt 5 LXQt was built with, so unless LXQt uses modules that have since been removed from that perspective in theory it should work. The other way (Using an older Qt with newer LXQt) won't work. Qt has been reasonably good at making this work from a historical perspective.
So...I did a test in a VM, and es expected, a zypper dup from KDE:Qt5 breaks most of the applications. The system runs, but LXQT as desktop is completely broken :-( Cheers Axel
