Let's try use the private version:

The issue is solved after applying this patch to dev-qt/qtbase.

Yes, kate-addons emerges correctly and without errors with your patch to qtbase, thank you.

[Comment 6 Leonid Kopylov 2024-08-25 16:25:46 UTC]

patch works for me also

[Comment 7 Sam James 2024-08-25 16:36:56 UTC]

Thanks. I've sent https://codereview.qt-project.org/c/qt/qtbase/+/585668 upstream but I could be more confident...
