I upgraded my system, from very old (12.x) to 15.x(vivid) version.
Since I use Kubuntu it uses heavily it’s own Qt version.
As long as I am aware that is not an issue since QtCreator configuration for QtVersion and kit point to internal V-Play version.
Anyway, after the upgrade, all V-play projects(old and completely new from templates) fail with:
Cannot mix incompatible Qt library (version 0x50401) with this library (version 0x50600)
Weird thing though, with the same QtVersion and kit settings, other(no V-Play) examples from QtCreator, work just fine.
Looks like it mixes 5.4(probably in my old system?) with 5.6.
I re downloaded all V-Play package and deleted QtCreator config in ~/.config/… directory.
Apart from loosing all configuration I still get this error.
Currently I use Qt 5.6(maintenance tool) because of 3D bits which I don’t see in 5.7, so didn’t download it yet.
I can see two auto detected QtVersions in QtCreator settings, both pointing to V-Play, not the system one.
Not sure what to do.
