Derivation / Everdo

Help
1

I’m quite new to Nixos but not to linux. Have been running Arch for a few years but recently got hit with a grub issue and let me know how unstable Arch can be despite having installed it with btrfs and taking automatic snapshots as well as backing up to my homelab. I did troubleshoot and get everything working again but now testing out Nixos. Have most things running smoothly especially when there is a pkg for my software.

I run a program called Everdo that’s not yet in Nixos pkg, but somebody has already created a derivation for it. The Nixos wiki page on derivation doesn’t make sense to me or doesn’t apply to what I’m trying to do, thus it’s very confusing. That is likely where Arch has thrived in having such a great wiki page.

My question is how do I get my nix config file to install a derivation as any other software?

Here’s the link to the code I’m trying to install Trying to package Everdo for NixOS (core dumped) - #3 by Andrei - Support - Everdo Community

Here’s the code

{ stdenv, fetchurl, autoPatchelfHook, makeWrapper, asar, dpkg, electron }:

stdenv.mkDerivation rec {
  name = "everdo-${version}";
  version = "1.5.14";

  src = fetchurl {
    url = "https://d11l8siwmn8w36.cloudfront.net/${version}/everdo_${version}_amd64.deb";
    hash = "sha256-erFYoYhVrxt+iT3B2kG4uAp39+ZLdCfTi1QC8q7uPbU=";
  };

  nativeBuildInputs = [ autoPatchelfHook makeWrapper asar dpkg ];
  buildInputs = [ stdenv.cc.cc ];

  sourceRoot = ".";

  unpackCmd = "dpkg-deb -x $src .";

  postPatch = ''
    asar e opt/Everdo/resources/app.asar app
    autoPatchelf app
    asar p app opt/Everdo/resources/app.asar
  '';

  installPhase = ''
    mkdir -p $out/bin

    cp -r usr/share $out/share
    cp -r opt/Everdo/resources $out/share/everdo

    substituteInPlace $out/share/applications/everdo.desktop \
      --replace /opt/Everdo/everdo $out/bin/everdo

    makeWrapper ${electron}/bin/electron $out/bin/everdo \
      --add-flags $out/share/everdo/app.asar
  '';
}

Put that derivation into a new file next to your configuration.nix, call it e.g. everdo.nix. Add it to environment.systemPackages like so:

environment.systemPackages = with pkgs; [
  ...
  (pkgs.callPackage ./everdo.nix {})
];

callPackage will import that file, which contains a function, and call by resolving the function arguments from nixpkgs.

That seems quite easy. Set it up and started to rebuild it then got:

error: Function called without required argument “asar” at /etc/nixos/everdo.nix:1, did you mean “acr”, “aha” or “air”?
(use ‘–show-trace’ to show detailed location information)

Using --show-trace gave me:

building Nix…
building the system configuration…
error: Function called without required argument “asar” at /etc/nixos/everdo.nix:1, did you mean “acr”, “aha” or “air”?

Try this, asar is in nodePackages:

This runs it, but the software screen is black. Maybe if I update it to a newer version, but now having an issue with hash mismatch. Where would I find the hash?

raphi, that was the final fix to get it to run. Except the software itself didn’t quite run right despite using the original version of the original poster. I did end up getting the software to run using an appimage. The solution is found on AppImage / Derivation

I appreciate your help and glad to have it working. My other programs will likely be easier as they are more mainstream.
