Start of Plasma & Frameworks Qt6 based

demm

Plasma 5.27 will be the last Plasma version based on Qt5, so it is getting time to see how far Plasma Qt6 based will build. That means, all of the Frameworks will have to be build on Qt6 first.
Close to 1/3 of the Frameworks (5.99.0 based) build on Qt6 are now in the [kde-next] repo. Not installable alongside Qt5 based versions, since the libraries share the same name (header files are all KF6xxxx named).

You can follow along there to see the progress. Milestones of something really working will be posted here.

It shows projects still not compileable

Adding all the needed Frameworks (5.99.0) to build Plasma is completed.
A start is now made to add Plasma 5.26.3 Qt6/kf6 based packages, about a quarter of the Plasma packages is up.
Still not something usable.

One (test) install is converted to Plasma 6. SDDM shows, ksplash runs too, but no plasma desktop yet (plasma-desktop package fails to build so far, issue with incompatible kio 5.99.0 for needed latest plasma-desktop patches, kio 5.100 is needed).

Plasma 6 in virtualbox, limited of course, but it is up.

First application added to the Frameworks 6/ Plasma 6/ KDE apps builds in kde-next.
Konsole (Qt6 based), works good, so now it is possible to actually do something with a pure Plasma 6 install:

After a few months of quiet, work has resumed to get ready for Plasma 6.
Upstream now has master (in git) set to Frameworks 6 (Qt6 based thus) & Plasma master is in the proces of doing the same.
Now all in kde-next are build directly from master git, so Frameworks there is at version 5.240.0 & Plasma is at 5.27.80.
Not many KDE Apps can be build yet, since almost all still look for kf5 (eventhough that kf5 could be Qt6 based.....). Kate is one exception, it is up in kde-next as kate6 23.03.80.

All of Frameworks 6, Plasma 6 and a few more apps are now build against Qt 6.5.0. It is getting far more usable with apps like konsole, gwenview, spectacle and kate fully working. A preview (Live only) ISO with Plasma 6 will be released shortly, 2 images of the current status:

Falkon & Dolphin are now also ready for use as kf6/Qt6 based applications. Once Yakuake 'sees' Konsole again, instructions will be posted here to convert a regular (non-production) install from Plasma 5 to Plasma 6. It actually is quite easy to do, and you can also go right back to Plasma 5 should you no longer wish to use Plasma 6.
