moc-generated code error at Qt6 when not at Qt5

[JonB]

@Axel-Spoerl
Thank you. So what would you like me to do about our difference in behaviour? :)
[I fetch all my Qt stuff from apt as supplied with Ubuntu 24.04 distro.]

I actually remember something similar, early when QVector was nuked for QList to prosper.

I think if you change it from QList<Bar *>bars to QList<Bar *> *bars it actually works. Axel is using a way later Qt6 version ( 6.8 vs 6.4.2) QList was probably touched again in between those versions, to fix this :D

But those are quite different types! :) Are you just showing me that to say what it could cope with?

Ah! Well in that case it's obviously not to be reported. Thanks for the heads-up.

With Qt5 I always had Qt 5.15 (or maybe 5.12) via apt under various Ubuntu releases over the years. And I have to say that was just great, I didn't encounter problems and I didn't need later versions. I suspected Qt6 would be problematic, looks like I get a quite older version and am going to have issues which really need a later version from TQtC :( Ho-hum....

@JonB what was the reason again, why you don't fetch the latest version from the installer or the repo (to compile yourself) ?

@J-Hilk

• I have never even attempted to download from TQtC, having seen the endless problems with downloads/mirrors. Fills me with dread....
• ...As does when I see people who for whatever reason (e.g. maybe to do with configuration, whatever it happens) get an error during compilation of the whole of Qt....
• I don't have the disk space in VM for Qt sources + compilation outputs.
• I don't have the memory in VM to compile it. Not to mention the requirements for QWebEngine.
• I share (development) with other people using Qt from Ubuntu distro. They are not going to want to fetch/compile/install or take from me.

Am I being difficult? ;-) It was all so simple with Qt5, everything worked. Now beginning to think of backing out of the whole of Qt6 and reverting to Qt5. But that would be a shame for my answering questions on this forum.

@JonB I Understand, I myself are still on 5.15.17 and I stay with 5 as long as possible.

But Android support is apparently already dropped for Qt5. So I have at most a year until I have to switch over :(

OMG! What platform/OS version are you on?

[J.Hilk]

@JonB windows, macOS, iOS, iPadOS & Android. Still so far all the latest available (not betas)

[JonB]

@J-Hilk Right, but not my Ubuntu 24.04 which I am moving to, and doing Qt as part of it.

[J.Hilk]

@JonB non of our customers use Linux, only reason why we support macOS is because its my development environment and its only a few steps more to deploy for it as well ;)
