[SOLVED] Issues with dev-qt/qtbase blocking world updates

I am stuck with a blocked world update for days now. At first I just ingored, assuming it would be eventually corrected in the next world update, but it has been persistent. It probably now more than a week since world updates are blocked here. The issue seems to involve dev-qt/qtbase, but I cant quite figure it out:

You're not using a desktop profile? This would be much easier otherwise.

Scan the output for "required by" string. These lines tell you that several packages are requesting USE flags set on dev-qt/qtbase:6, which indeed your configuration of dev-qt/qtbase:6 looks to be providing - but other dev-qt/* packages like qtdeclarative need these flags *in sync* with qtbase:6, like qtdeclarative. And really, you want to have USE like icu, and opengl, and wayland, and vulkan, ... globally enabled, but it seems like you did that only selectively via package.use for qtbase:6 yet?

Updates bring changes, sometimes bigger changes (like Qt5 -> Qt6, KF5 -> KF6):

Not impossible to use package.use for everything but you'll have a lot of figuring out to do, esp. given portage is not very helpful at showing the proper solution to this type of conflict. Either way, it won't go away magically by waiting w/o a desktop profile.

If really want to keep your current profile and want minimal, I'd at *least* USE="opengl icu kf6compat" globally and cleanup your package.use to avoid mismatches. May need more depending on what you're installing but these are hard to pass w/ qt6+kde.

Albeit I think trying to be minimal when you're installing qt6 and kde packages doesn't make much sense, few extra default USE weights little in the balance. Edit: So may just want to set most desktop USE flags to get the expected experience, or ideally merge the desktop profile with your current, albeit that's slightly more advanced usage.

I do have 23.0/split-usr/hardened. What I'm doing from time to time is to eselect the plasma profile and run "emerge -p @world" to check if there are USE flags I should add here. Then I switch back to my profile and act accordingly to the output.

ftr, it doesn't look as if kf6compat will be doing anything for your system. In that area, Portage is able to autoresolve the blockers, automatically cleaning up the older KF5 version. And probably all of KF5 will be cleaned up by a follow-up depclean run after the upgrade.

It worked!

I have added for global use the flags opengl, icu and wayland, and in the sequence the system asked for two minor package.use changes. After that there was a huge world update, approximately 140 updates, which took nearly a whole night, but concluded without errors. The subsequent cleanup removed 43 packages, and now I have the system "unlocked" again. For future reference, this is my new make.conf file:
