Talk: Nix-writers

start this shell.nix

{ pkgs ? import <nixpkgs> { } }:
pkgs.mkShell {
  buildInputs = with pkgs;
    [
      (pkgs.writers.writeC "hello-world-ncurses" {
        libraries = [ pkgs.ncurses ];
      } ''
        #include <ncurses.h>
        int main() {
          initscr();
          printw("Hello World !!!");
          refresh(); endwin();
          return 0;
        }
      '')
    ];
}

I get the error :
