gnu-cobol-nix

Nix flake to build GnuCOBOL and GnuCOBOL Contrib on Linux & MacOS. This flake fetches source from Github mirrors 1, 2 of the upstream SourceForge SVN repositories.

Usage

{
  description = "Your nix flake with GnuCOBOL. Hack the planet!";

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";

    gnu-cobol= {
      url = "github:rupurt/gnu-cobol-nix";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = {
    flake-utils,
    gnu-cobol,
    nixpkgs,
    ...
  }: let
    systems = ["x86_64-linux" "aarch64-linux" "x86_64-darwin" "aarch64-darwin"];
