Dependency on `qtbase` ?

[Pol Dellaiera]

Hello,

I tested this flake and I noticed that it took a while to compile qtbase. Therefore, I'm wondering why qtbase is required. Can you help?

This is the relation:

I observed the rebuild while updating the nixpkgs of example/cpu yesterday. Then I checked if hydra-check fails for qtbase:

nix run github:nix-community/hydra-check -- qt6.qtbase --arch aarch64-darwin
Build Status for qt6.qtbase.aarch64-darwin on jobset nixpkgs/trunk
✔ qtbase-6.7.1 from 2024-05-22 - https://hydra.nixos.org/build/260396540

But it doesn’t .

I think there is no cache for the qtbase in nixpkgs-unstableand the hydra-check could be for master?

[Pol Dellaiera]

Perhaps it would be better to rely on nixos-unstable?

[Shivaraj B H]

Will it be any different? I thought both of them follow master and lag behind a couple of days? Is there anything more that I might be missing? Also since I am aiming to support both Linux and macOS, I thought I should go with nixpkgs-unstable.

[Shivaraj B H]

Its not rebuilding qtbase anymore, I updated to the latest nixpkgs-unstable: 483f6f0

[Pol Dellaiera]

Cool let me try.

Looks like it's fixed. Thanks!
