is this just delegating to clang ?

Hey guys, I am trying to build an armv7l image cross compiling from x86_64-linux to armv7l-linux. I ran into:

error: builder for '/nix/store/gzf7cxdnlm8jy0xhil6930p2684yjs4m-perl-armv7l-unknown-linux-gnueabihf-5.38.2.drv' failed with exit code 2;
       last 10 log lines:

       For full logs, run 'nix-store -l /nix/store/gzf7cxdnlm8jy0xhil6930p2684yjs4m-perl-armv7l-unknown-linux-gnueabihf-5.38.2.drv'.

How can I troubleshoot this further (still early days with Nix/NixOS for me).

This is the output I got when I tried to crosscompile this sd-image.nix

{ lib, ... }: {
  nixpkgs.buildPlatform = "x86_64-linux";
  nixpkgs.hostPlatform = "armv7l-linux";
  imports = [
    <nixpkgs/nixos/modules/installer/sd-card/sd-image-armv7l-multiplatform.nix>
  ];

# config
  boot.supportedFilesystems.zfs = lib.mkForce false;
  system.stateVersion = "24.05";
  # Enable the OpenSSH daemon.
  services.openssh.settings = {
    enable = true;
    PasswordAuthentication = true;
  };
}

I just wanted to learn how to dig deeper when such a problem occurs.

You'd build the offending derivation with --keep-failed and then inspect for any logs or clues
