Hotspot fails to build with new QT

[turol]

QT6 just updated to a newer version dev-qt/qtbase-6.9.1 and hotspot failed the rebuild

It seems more confusing. The latest kddockwidgets in this overlay is 2.2.1, but 2.2.5 has apparently been released in the main gentoo repository. Unfortunately, hotspot::kdab-overlay specifically depends on kddockwidgets::kdab-overlay, which conflicts with kddockwidgets::gentoo (file collisions, obviously). I'm not sure what type of coordination is necessary, or if I just need to request hotspot also be added to ::gentoo.

if I just need to request hotspot also be added to ::gentoo.

That or GURU, I unfortunately do not run Gentoo on my desktop anymore and I don't think anyone does in KDAB at the moment. I could blindly remove the KDDW ebuild from this repository since ::gentoo has an up-to-date version now, which would fix your issue specifically.

Thanks.
I just raised this issue in https://bugs.gentoo.org/624062 which is a request to add hotspot to ::gentoo from 2017. Perhaps an easier short-term is to let hotspot use either kddockwidgets::gentoo OR kddockwidgets::kdab-overlay although the latter is now out of date, so maybe removal is better - but opening the dependency for hotspot.

Trying to compile hotspot 1.5.1 (from a local Gentoo overlay) it fails with the above error, so that is still the underlying issue here, but should this be posted at kdab instead of kdab-overlay?

Current git tip of tree builds (but I didn't actually test it) so making a new release or backporting the fix should do it. In either case it needs an update to the overlay.

This is the commit that needs to be added as a patch KDAB/hotspot@ec54b1e
