Build failure: mcpelauncher-ui-qt

[surfaceflinger]

Nixpkgs version

• 1ec9dbf (master as of right now)

Steps to reproduce

1. nix build github:NixOS/nixpkgs/1ec9dbf3abfcd01a520a5a19a25d60c2ab28fac4#mcpelauncher-ui-qt -L

Can Hydra reproduce this build failure?

Search doesn't work for me so idk.

Relevant log output

possible fix? minecraft-linux/mcpelauncher-ui-qt#57

[Morxemplum]

So the pull request that you have linked seems to close an issue that produces pretty much the same log output that you have included in this issue. As the original issue describes, this is a failure with Qt 6.9.0, which has been merged into nixpkgs a few weeks back.

As this pull request is fairly recent, there currently is no point release that incorporates the needed patch. We'll need to fetchpatch as a workaround until the next release comes out.
