Passing arguments for callPackage build from flake.nix

Help
1

Hi, I’m trying to create a flake from a custom package build.

The setup is simple

{ lib, stdenv, buildGoModule, fetchFromGitHub, libobjc, IOKit, nixosTests }:

let
  # A list of binaries to put into separate outputs
  bins = [
    "geth"
    "clef"
  ];

in buildGoModule rec {
  pname = "core";
  version = "1.12.0";

  src = fetchFromGitHub {
    owner = "LarissaBlockchain";
    repo = pname;
    rev = "v${version}";
    sha256 = "sha256-UbRsY9fSUYAwPcLfGGDHeqvSsLKUKR+2a93jH5xA9uQ=";
  };

  vendorHash = "sha256-dOvpOCMxxmcAaticSLVlro1L4crAVJWyvgx/JZZ7buE=";

  doCheck = false;

  outputs = [ "out" ] ++ bins;

  # Move binaries to separate outputs and symlink them back to $out
  postInstall = lib.concatStringsSep "\n" (
    builtins.map (bin: "mkdir -p \$${bin}/bin && mv $out/bin/${bin} \$${bin}/bin/ && ln -s \$${bin}/bin/${bin} $out/bin/") bins
  );

  subPackages = [
    "cmd/abidump"
    "cmd/abigen"
    "cmd/bootnode"
    "cmd/clef"
    "cmd/devp2p"
    "cmd/ethkey"
    "cmd/evm"
    "cmd/faucet"
    "cmd/geth"
    "cmd/p2psim"
    "cmd/rlpdump"
    "cmd/utils"
  ];

  # Following upstream: https://github.com/ethereum/go-ethereum/blob/ea9e62ca3db5c33aa7438ebf39c189afd53c6bf8/build/ci.go#L218
  tags = [ "urfave_cli_no_docs" ];

  # Fix for usb-related segmentation faults on darwin
  propagatedBuildInputs =
    lib.optionals stdenv.isDarwin [ libobjc IOKit ];

  passthru.tests = { inherit (nixosTests) geth; };

  meta = with lib; {
    homepage = "https://geth.ethereum.org/";
    description = "Official golang implementation of the Ethereum protocol";
    license = with licenses; [ lgpl3Plus gpl3Plus ];
    maintainers = with maintainers; [ RaghavSood ];
  };
}

And then the flake.nix

{
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs";
    flake-utils.url = "github:numtide/flake-utils";
  };
  outputs = {self, nixpkgs, flake-utils } :
    flake-utils.lib.eachDefaultSystem (system:
      let
        pkgs = nixpkgs.legacyPackages.${system};
        larissa = pkgs.callPackage ./larissa.nix  { };
      in {
        devShell = pkgs.mkShell { buildInputs = [ larissa ]; };
      });
}

This is the error that I get:


[vini@nixos:~/Workstation/larissa]$ nix develop

Maybe you want:

pkgs.callPackage ./larissa.nix  { inherit (pkgs.darwin) IOKit; };
