To compile and use proxmark3 on NixOS you need some packages. I created a nix-shell file with all needed dependencies.
Copy this file as shell.nix
to the cloned proxmark3 folder and run sudo nix-shell
. Continue then the normal compile guide.
with (import <nixpkgs> {});
mkShell {
buildInputs = [
readline
ocamlPackages.bz2
ocamlPackages.ssl
gcc-arm-embedded
];
}
