Step by step usage instructions?

kathodler commented 2 years ago

Hi just new to NixOS so was wondering if you might be able to share some detailed instructions on how to set this up as a newb? I am really not sure where to begin with flakes. I have a basic nixos installation and am familiar with nix syntax but step by step instructions would really help from the perspective of someone who wants to do solana development in nixos.

Here's a simpified version of what I use:

{
  description = "Solana dev flake example";
  inputs.nixpkgs.url = "github:NixOS/nixpkgs/nixos-22.05";
  inputs.solana.url = "github:itsfarseen/solana-flake";

  outputs = { self, nixpkgs, solana }: 
  with import nixpkgs {
    system = "x86_64-linux";
  }; {
    devShells.${system}.default = pkgs.mkShell {
      packages = with pkgs; [
        solana.packages.${system}.default
      ];
    };
  };
}

Put the above code in a file named flake.nix in the root folder of your project and run nix develop to get into the dev shell.

Hi @itsfarseen. I'm getting an error with your code above. How to fix?
