Change:
libsForQt514.qt5.qtwebengine currently fails to build locally and on . The interessting line seems to be: The last successful build on hydra was linked to . After that it seems to fail (starting with ) Bisecting takes forever. I would hazard a guess that it has to do with and PR which broke some other packages as well. EDIT: EDIT2: The error seems to stem from the c++ upgrade. The error message is referenced e.g. here Steps to reproduce the behavior: nixpkgs master -build -A libsForQt514.qt5.qtwebengine . Build should succeed. If applicable, add screenshots to help explain your problem. Add any other context about the problem here. Please run and paste the result.
It's most likely due to mixing gcc versions, as that's not 100% compatible in C++. qt514 (and qt512) get overridden to gcc10, whereas the default is gcc11. (For x86_64-linux; some others have other combinations.)
Closing since libsForQt514 was removed from master.
