#Nix definition of roboRIO platform

This flake provides a definition of the roboRIO platform, for use in Nix. It also provides an overlay which adds the necessary compiler flags for building software on the roboRIO. Specifically, it adds -D__FRC_ROBORIO__=..., which is necessary for WPILib to build correctly.

#Example

The following example flake will cross-compile GNU Hello for the roboRIO:

{
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs";
    flake-utils.url = "github:numtide/flake-utils";
    frc-systems.url = "sourcehut:~jhagborg/frc-systems-nix";
  };

  outputs = { nixpkgs, flake-utils, frc-systems, ... }:
    flake-utils.lib.eachDefaultSystem (system:
      let
        pkgs = import nixpkgs {
          inherit system;
          crossSystem = frc-systems.lib.roborio;
          crossOverlays = [ frc-systems.overlays.roborio ];
        };
      in {
        defaultPackage = pkgs.hello;
      }
    );
}
