Does it make sense to try to build Falkon against QT6 on Debian "Bookworm" 12?

[Jens Radloff]

Hi Juraj,

Thanks for your information. 

I think it is the best if I start testing Falkon based on QT6 in an 
environment that completely fulfills the requirements for compiling such Falkon 
source code. 

The Debian Testing release called "Trixie" currently does not fulfill the 
required version number 5.240.0+ of ECM because its package "extra-cmake-
modules" currently has version 5.107.0-1, see

https://packages.debian.org/trixie/extra-cmake-modules

The version number of the KDE Frameworks that are part of "Trixie" currently 
is 5.107.0-1, see the package "frameworkintegration" at

https://packages.debian.org/trixie/frameworkintegration

So "Trixie" currently is not suitable for compiling the Falkon source code 
that utilizes/requires QT6, ECM in version 5.240.0+ and KF6.

I never used any Debian testing release like "Trixie", I am not familiar with 
testing a future stable Debian release. 

Would it be possible that Debian would replace the current ECM and KF5 package 
with newer versions we need for testing Falkon during the remaining time until 
"Trixie" will become the next stable Debian release?

Regarding KF6 you wrote (and I found appropriate information on a German web 
site containing news about Linux items) that KF6 probably would be released in 
February 2024. Will then KF6 be part of "Trixie"?

Best regards,

Jens
