qtbase-6c09620? What's that? qt5.qtbase is on cache.nixos.org

And qt5.qtbase.meta.maintainers are four people, not including myself.

[LovingMelody]

It's not being pulled from the cache (by choice). It is qt5.qtbase

I see. The src in current master is qtbase-d3b21bc for .9 so you might try to update master first...

Edit: the actual fatal error is

https://gist.github.com/Fuzen-py/582e3192a0a3183f95b744ea0fdcab6a#file-qtbase-5_15_8-log-L2026

Removing the ANSI escapes:

global/qfloat16_f16c.c:52:6: error: redefinition of void qFloatToFloat16_fast(quint16*, const float*, qsizetype)

[K900]

Can you post the exact derivation you're building, or a nix-diff of it compared to unchanged nixos-unstable and/or master?

[LovingMelody]

Nix-diff against master:
https://gist.githubusercontent.com/Fuzen-py/582e3192a0a3183f95b744ea0fdcab6a/raw/16eb0c668dd1d8fb99e354816d8c6f8ad7443824/Nix-diff

I expect majority of the diff is #226795 merged just hours ago.

Build failure is from editing cflag. Closing.
