Follow-up to #102216. Please see the comments there. Patches are probably needed as well.

I have regular crashes in some programs because auf 5.15.0 regressions.

[freezeboy]

Maybe it is safer to close this one

[unclechu]

@freezeboy Sorry, could you clarify please why did you close it?

[freezeboy]

As the other pr is struggling with the patches i guess this one is not worth the effort

[poelzi]

It does not make sense to go to 5.15.1 when 5.15.2 is already available.

[ttuegel]

Qt 5.15.1 has some serious regressions (reported by Plasma upstream) and I would strongly prefer to go straight to Qt 5.15.2.

@ttuegel Ok for me but I can't run nixpkgs-review, so if someone can check this version is ok, it will help.

I rebased on my machine and started a build of qt5 to be sure that at least the lib is building

[ttuegel]

I can't run nixpkgs-review, so if someone can check this version is ok, it will help.

I'm building now. The staging branch is badly broken right now, so I cherry-picked onto master for testing. If it works there, I'd say it's good enough to go into staging.

Whats the progress here ? I have regular crashes due this buggy qt 5.15.0 and I start to get really annoyed by the slow progress of getting patch level updates into the tree.
Despite the fact I love nix, this is an perfect example why major distributions like ubuntu are way more stable and enterprise ready then NixOS and I can only suggest it with half a heart and will mention pain like this will come to everyone interested in nixos..... unfortuntelly :-/

[freezeboy]

I didn't receive any feedback from the build process, so still waiting in case there is a problem.

[ttuegel]

I'm going to close this in favor of #106118. We should consolidate our efforts there because it is the most complete of the Qt 5.15 update pull requests.
