It seems there is something wrong with the packaging of Qt3D. When I try to run any Qt3D examples I get: "Cannot mix incompatible Qt library (5.15.5) with this library (5.15.6)" When I run the application with qml-module-qt3d not installed I just get QML warnings about missing QML modules. I tried to locally build the debian packages for qt3d-opensource-src-5.15.5+p22.04+tunstable+git20220909.0022, but that failed to build out of the box. I then cloned the qt3d git repo and built the head of the 5.15 branch and installed it to /usr (not on a production machine). After the install Qt3D applications started working again. Same problem is also present in the p20.04 version Regards, Kåre
I can't recreate the problem using gammaray, what are you running and on what neon edition and base? I've started a rebuild of qt3d incase that helps.
The rebuild is done, if you are using /user you'll need to add /release to your apt sources.list.d/neon.list
Thank you for your bug report! However this bug report was created/provided previous to 01/01/2023 and also has not received any updates since before 01/01/2025. Unfortunately KDE neon no longer provides updates for anything older than noble 24.04 based edition's. Please upgrade to KDE neon noble and if you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report. Thanks for understanding!
Fixed log ago :)
