Build errors about nix-software-center

[vlinkz]

I think the reason for the error is that you're using NixOS 22.05 stable without flakes, and the rust version is too old to compile some of the dependencies. I'll look into possible workarounds

Still fails btw:

[Zahrun]

I figured out that rust 1.66 is also already packaged in 22.11, but not used by default.
So, as a workaround, I modified default.nix to use that specific version of rust in Zahrun@8097b31.
There might be a better way to select the rust version, and maybe allow it to be set as an override or an overlay or something, but I don't know how to do that, and for the time being this workaround allows to build in nixos-22.11:

nix-software-center = (import (pkgs.fetchFromGitHub {
    owner = "zahrun";
    repo = "nix-software-center";
    rev = "8097b317fd1d5d0fd2d4d7b666086edd9ff8d129";
    sha256 = "sha256-ZVtw/ChkS3sSA4qm6CSvZQxXeES+PQwXmgaZxddixQo=";
  })) {};

I did the same for nixos-conf-editor in Zahrun/nixos-conf-editor@03eac62:

nixos-conf-editor = (import (pkgs.fetchFromGitHub {
    owner = "vlinkz";
    repo = "nixos-conf-editor";
    rev = "03eac62c40003516fa256be64df265a088958ae9";
    sha256 = "sha256-Nb9IgSdgZQ4GllGStsINL1KfLzX2XxEAEhr8tEWBr4c=";
  })) {};

Please note that this workaround will not work in unstable because rustPackages_1_66 does not exist any longer there, so this is to use only in 22.11.

EDIT: This also works:

{ config, pkgs, ... }:
let
  unstable = import (builtins.fetchTarball {
    url = "https://github.com/NixOS/nixpkgs/archive/nixos-unstable.tar.gz";
  }) {config = config.nixpkgs.config;};
  nix-software-center = import (pkgs.fetchFromGitHub {
    owner = "vlinkz";
    repo = "nix-software-center";
    rev = "0.1.1";
    sha256 = "0frigabszyfkphfbsniaa1d546zm8a2gx0cqvk2fr2qfa71kd41n";
  }) {pkgs = unstable;};
in
{
  environment.systemPackages = with pkgs; [
    nix-software-center
  ];
}

And similarly

nixos-conf-editor = import (pkgs.fetchFromGitHub {
    owner = "vlinkz";
    repo = "nixos-conf-editor";
    rev = "0.1.1";
    sha256 = "sha256-TeDpfaIRoDg01FIP8JZIS7RsGok/Z24Y3Kf+PuKt6K4=";
  }) {pkgs = unstable;};
