Qt5 upstream OSS support ended on 2020-12-08. Since then, public availability of commercial 5.15 LTS releases is delayed by 1 year. That concerns anything they fix in their private 5.15 branch that is not a Qt6 fix and therefore backportable from public branches - backports, however, that also get more complex with every new Qt6 release. > - Most of KDE projects have ported away to Qt6. > - No other DE/WM based on Qt5 is left in ::gentoo to benefit from the option. > - Therefore I do not plan to put any more time into Qt5 packaging, much less > backporting LTS fixes to KDE Qt repositories. > - GCC, ICU, Python, ... may at any future release break Qt5, QtWebEngine in > particular. Since our users build from source, Gentoo gets hit first with any build issues. That means we can't sit back and do nothing until a real showstopper arrives. This tracker starts as a collection of tasks to port away from Qt5 while we still have time to: - check, if Qt6 support exists and just waits to be enabled, maybe after a version bump - for simple packages with qmake build system, check if s/eqmake5/eqmake6/ may works - go upstream to inform about the need to port to Qt6 or ask about project status for slow-moving repositories - collect patches from other distributions - port it ourselves and submit it upstream ofc

No talking in tracker bugs please. If it was not yet clear by the looks of this bug, individual bugs shall be filed against affected packages, blocking this tracker.
