Regression on master: a 'i686-linux' with features {} is required to build ..., but I am a 'x86_64-linux'

[pshirshov]

Some packages fail to build on master with an obscure error like:

error: a 'i686-linux' with features {} is required to build '/nix/store/3vkazf8pw0bgaxqa2a9l2rhpa1f7xlwc-libva-minimal-1.8.3.drv', but I am a 'x86_64-linux' with features {benchmark, big-parallel, kvm, nixos-test}

Namely:

1. a2ps
2. libva-minimal

Could you give me any hint what should I look at?

[iblech]

Hm, I cannot reproduce this (neither for a2ps nor for libva-minimal). I'm on an x86_64 NixOS system. Could you give some further details regarding your setup? Or did the problem evaporate in the meantime?

[Artturin]

can't repro, next time follow the issue template

[mtoohey31]

I'm running into this issue on the latest nixos-unstable, specifically with libva-minimal-1.8.3. Should I provide the details here, or should I open a new issue? I'm running a bisect now, but it'll take a while to pinpoint the problem commit as my configuration requires kernel patches.

It does indeed indicate that it's meant for an i686 system, which mine is not.

So the bisect wasn't useful... I left it running with the kernel patches disabled but the problem commit it returned didn't make any sense. I'm re-running it with the kernel patches enabled, but that'll take even longer. In the meantime, all my configuration is here: https://github.com/mtoohey31/infra. The commands I'm running are: nix flake lock --update-input nixpkgs && nixos-rebuild build --flake .#, and that's on my system with the zephyrus hostname, so it should be building .#nixosConfigurations.zephyrus. The encrypted secrets.nix file might make it a pain to get things building, replacing it with something like the following might be enough to fix the issues there:

{
  userscripts = {};
  systems = {
    zephyrus = {
      ssh_port = 12345;
      system_ssh_public_key = "";
      user_ssh_public_key = "";
      username = "username";
      wg_ip = "";
    };
  };
}

(I know encrypting a plaintext file in a git repository isn't super secure, as you can see from the values above though, I'm only using it for security-by-obscurity-type things.)

Also, here's the metadata, if that's of any use:

[user@system:~]$ nix-shell -p nix-info --run "nix-info -m"
- system: `"x86_64-linux"`
 - host os: `Linux 5.17.7, NixOS, 22.05 (Quokka), 22.05.20220516.1d7db1b`
 - multi-user?: `yes`
 - sandbox: `yes`
 - version: `nix-env (Nix) 2.8.1`
 - channels(root): `"nixos-21.11"`
 - nixpkgs: `/nix/store/57zwl7b883kkya60akvg6wssl1qkxwl5-source`

It's the same bug as https://github.com/NixOS/nixpkgs/issues/86506#issuecomment-623746883

The commit that caused it in your config is https://github.com/mtoohey31/infra/commit/c43c7435e3772a65be302ea43c8e4c2cc370094a

Ahh, that makes sense, thank you! I'll confirm that was the problem and we can close this in just a minute, after things build sucessfully.

Edit: yep, that fixed it, things are building now! Thanks again!

OK, moved to the Nix issue.
