[gebner]

I didn't try to build everything that depends on qt, but I don't expect much breakage since this is just a point release.

KDE frameworks package purpose fails and thereby the application okular as well.

Rebuilding my system now with this update based on top of #101369.

[unclechu]

It probably closes #98009 too.

[doronbehar]

@gebner could you please add the patch I wanted to add in #100041 ?

See also: #99456 (comment) .

[gebner]

@doronbehar The patch is already included.

[FRidh]

ffe65c3 is needed for kpurpose.

Rebuilt my system successfully with this change. Did not test runtime though.

[unclechu]

It seems this one doesn’t #98009. Am I testing this correctly? It took a while before everything compiles.

nix-shell -E 'let pkgs=import (fetchTarball {url="https://github.com/NixOS/nixpkgs/archive/5856b4c99356e63119daa14f01626891b03af539.tar.gz";}) {}; in pkgs.mkShell {buildInputs = [pkgs.vlc];}' --run vlc

nix-shell -E 'let pkgs=import (fetchTarball {url="https://github.com/NixOS/nixpkgs/archive/5856b4c99356e63119daa14f01626891b03af539.tar.gz";}) {}; in pkgs.mkShell {buildInputs = [pkgs.audacious pkgs.vlc];}' --run audacious

[unclechu]

First I applied a patch made of #102594 on top of nixos-unstable, it fixed dark theme for vlc and psi-plus for me but not audacious. Then I applied also this PR:

(set -eo pipefail && curl --fail -Ls https://github.com/NixOS/nixpkgs/pull/102216.patch | git apply)

And this also fixed audacious for me.

I rebuilt the system by this command (while being in a directory of nixpkgs repository):

sudo nixos-rebuild switch -I nixpkgs="$PWD"

I didn’t test this MR without #102594 yet.

[unclechu]

I tested this PR separately and it only fixed audacious for me, vlc and psi-plus were still having light theme. So both #102594 and #102216 to fix Adwaita Dark for Qt applications.

[doronbehar]

Thanks for your report @unclechu, very appreciated.

[poelzi]

This should go into nixos 20.09 or better #104448 since it got more bugfixes as well.

[ttuegel]

I'm going to close this in favor of #106118. We should consolidate our efforts there, as it is the most complete pull request in the Qt 5.15.2 series.
