Error: bad value ('armv8-a') for '-march=' switch

[bobbbay]

Hey y'all! I'm running Flakes on NixOS WSL, and want to compile to my RPi 4 (sd-aarch64). Regrettable, after running nixos-generate -f sd-aarch64, I get the following error:

error: bad value ('armv8-a') for '-march=' switch

I've attached the full output for more details.

What am I doing wrong?

Thank you in advance!

[bobbbay]

Coolly enough, the regular -f iso builds, which makes sense since this error specifically mentions armv8-a.

[Lassulus]

I'm no expert on cross compiling, but it seems your gcc (or whatever compiler that is) does not support compiling for arm on your platform. Hopefully someone upstream (like on https://github.com/nixos/nixpkgs) can help you more.

[bobbbay]

Hey Lassulus,

Thank you! Funnily enough, I don't really have a compiler available in my shell... gcc, clang just aren't enabled (I'm sure they're on my system somewhere, though). Honestly, I expected nixos-generator to "just take care of it", including but not limited to pulling in a compiler. Am I getting this wrong, is that not how it works?

Funnily enough, now that I think of it, I noticed the cross-compiling header in the README but never added binfmt to my configs. But, after taking a look at the given example, I can't seem to understand how to configure these lines. I assume I won't use QEMU for cross-compiling? 🤪

Some guidance on this would be appreciated!

[Lassulus]

actually it uses QEMU for "cross-compiling" but that does not seem to be the issue here. Maybe try copying these binftm files and it could work then? nixos-generators is in itself just a small frontend around nixpkgs. Thats the place where most of the magic happens. we just pack some of its functionality inside a nice CLI. afair the binfmt stuff is now also in upstream nixos, i have it just configured via:

boot.binfmt.emulatedSystems = [
  "aarch64-linux"
];

[bobbbay]

Okay awesome, thank you very much.

Rebuilt system and proceeded to rebuild the image. Same error.

In this case, if you're certain this is an upstream error, please give me the +1 and I'll open an issue in nixpkgs.

Cheers!

[Lassulus]

uhm, maybe it works with 21.05 now? can you recheck? otherwise I guess an upstream issue could be more helpful to you :D
