Compiling and adding program not in nixpkgs to PC, compiling error

Help
1

I’m trying to add this program to my PC: GitHub - playit-cloud/playit-agent: The playit program

And I’m able to compile and run by downloading the tar.gz, extracting it, cd into the folder and running nix-shell -p cargo --command "cargo run --release --bin=playit-cli -- --help"

Now I was trying to add it to my configuration.nix file. (I use my flake, but it shouldn’t be relevant). So I added this to my configuration.nix file:

  imports = [
    (import ./nixFiles/playit-cli.nix)
  ];

and this is my playit-cli.nix file:

{ stdenv, fetchurl, pkgs, ... }:

let
  version = "1.0.0-rc2";
  src = fetchurl {
    url = "https://github.com/playit-cloud/playit-agent/releases/download/v${version}/playit-cli";
    sha256 = "1rb4jlwbixv0r1pak83prvsa79mj4096jdzjiyngdp5p9khcims9";
  };

in stdenv.mkDerivation {
  name = "playit-cli-${version}";
  buildInputs = [ pkgs.cargo ];
  src = src;
  installPhase = ''
    tar xfz $src
    cd playit-agent-${version}
    cargo build --release --bin=playit-cli
    mkdir -p $out/bin
    cp target/release/playit-cli $out/bin
  '';
  meta = with stdenv.lib; {
    description = "Playit-cli agent ${version}";
    homepage = "https://github.com/playit-cloud/playit-agent";
    license = licenses.gpl3;
    platform = platforms.unix;
  };
}

but I get this error on compile:

If I remove the three dots from the first line, so it is:

I get this error instead:

I’ve tried changing the contents of playit-cli.nix to the GNU Hello package, and I get the same error as the one immediately above

I’m not proficient with nix, and these error messages leave me at a loss, I can’t find anything in google about them
Thanks in advance! :slight_smile:

Few remarks:

  • the file that you try to import is a derivation, not a module, so you don’t want to put it in imports (also in this section you should not call import in the list, it’s just a list of file). Instead it’s a program. So you should do something like:
system.environmentPackages = with pkgs; [
  (callPackage ./playit-cli.nix {})
];
  • I have never used cargo, so I’m not sure if your derivation will work. But it could be easier to directly build the package from source using rustPlatform.buildRustPackage as explained here Rust | nixpkgs.

Thank you so much @tobiasBora :slight_smile:

You were right, with callPackage I’m now able to compile if I use the code from GNU Hello Package, my derivation isn’t working yet tho, it’s giving me:

error: attribute 'lib' missing

I’ll take a look at your suggestion about rustPlatform.buildRustPackage. Thanks a lot again :slight_smile:

Made it work in the end liek this :+1:
