nixos:release-18.03: build failure of nixpkgs.qt5.qtwebengine.x86_64-linux

[erikarvstedt]

nixpkgs.qt5.qtwebengine.x86_64-linux fails to build.
Last successful build was 12 days ago.

This causes many failing dependees, particularly all PyQt projects.

Thats darwin only. I have built it two times on Linux this week when going 18.03 (took about 2 hours each).

Is there some way of triggering a rebuild on Hydra?

Should be fixed now: https://hydra.nixos.org/eval/1442447?filter=qtwebengine&compare=1442329&full=

Thank you!

Thanks! If this was a Hydra issue, not a nixpkgs error, is there anything to fix in Hydra?

I suspect it's missing dependency between some of the make targets (upstream), so it fails based on your luck (and available parallelism).
