Unable to run on Windows ARM with Snapdragon X Elite

[cwhite92]

Bug description

NixOS imports fine on Windows ARM but when attempting to run NixOS via wsl -d NixOS the following error is thrown on Windows ARM with a Snapdragon X Elite (Microsoft Surface 7):

Catastrophic failure
Error code: Wsl/Service/E_UNEXPECTED

Happy to get more detailed logs if needed (not sure how though). Not sure if it's relevant but Ubuntu and Kali Linux both seem to work fine.

To Reproduce

1. Follow Quick Start instructions in README to import NixOS into WSL
2. Attempt to run NixOS via wsl -d NixOS
3. Above error is given

me too

i got wsl logs via collect-wsl-logs and i am analyze it right now

[nzbr]

Just to be sure: Did you build your own tarball targeting aarch64-linux? The one from our releases is for x86_64 and will not run on ARM

[RoadRoller01]

@nzbr cool, but how?, i have nix on my other x86 machine, so how i can force it to build for aarch64?

[RoadRoller01]

hello i build via debian arm wsl, with this commit #530 and it still did not work, the error it appear to cause the problem is

If you are using a flake based config it should be something like

outputs = { self } @inputs:
  nixosConfigurations.<hostname> = {
    /* ... */
    system = "aarch64-linux";
  };

Or are you talking about cross compiling?

[nzbr]

@RoadRoller01 where did you get those logs from? What does dmesg say (run it in another distro)

[RoadRoller01]

i got the logs from wsl, via https://github.com/Microsoft/WSL/blob/master/diagnostics/collect-wsl-logs.ps1

[RoadRoller01]

dmesg? do you mean the dmesg of the distro i am building the repository on? idk how it will help you yet i will tell you

[nzbr]

The VM is shared, so dmesg in any distro on the same machine will show the kernel logs for all other distros as well

[RoadRoller01]

oooh okay 👍, i can’t do it right now, so i will send it tomorrow.

[RoadRoller01]

dmesg.txt @nzbr that's it
