Gdb executable not found

I have added gdb to my home-manger config

  home.packages = [
    pkgs.cloc
    pkgs.ccls
    pkgs.direnv
    pkgs.gdb
    pkgs.git
    pkgs.gnumake
    pkgs.htop
    pkgs.ispell
    pkgs.mercurial
    pkgs.pass
    pkgs.python3
    pkgs.ripgrep
    pkgs.sbcl
    pkgs.texlive.combined.scheme-medium
    pkgs.tig
    pkgs.watchman
  ];

But unfortunately after home-manager switch it is still nowhere to be found

% which gdb
gdb not found

Any ideas?

Is your PATH properly setup? Does it work when reopening the terminal or relogging?

I definitely think so, I installed tig just to ‘proof’

 % ls ~/.nix-profile/bin | grep tig

 % tig

zsh: command not found: tig

% home-manager switch
