`libstdc++.so.6` not available in template

[hknlof]

Not a C++ developer. I assume enough C and especially C++ developers use libstdc++.so.6. When building a project, which downstream depends on it, I receive the following failure:

ImportError: libstdc++.so.6: cannot open shared object file: No such file or directory

Hence, it might make sense to add the LD_LIBRARY_PATH?

  description = "A Nix-flake-based C/C++ development environment";

  inputs.nixpkgs.url = "https://flakehub.com/f/NixOS/nixpkgs/0.1.*.tar.gz";

  outputs = { self, nixpkgs }:
    let
      supportedSystems = [ "x86_64-linux" "aarch64-linux" "x86_64-darwin" "aarch64-darwin" ];
      forEachSupportedSystem = f: nixpkgs.lib.genAttrs supportedSystems (system: f {
        pkgs = import nixpkgs { inherit system; };
      });
    in
    {
      devShells = forEachSupportedSystem ({ pkgs }: {
        default = pkgs.mkShell.override {} {
            packages = with pkgs; [

          };
      });

I also encountered this issue when using Poetry to install Spacy[transformer].

I googled and many people had the same problem. This or libz is not found.
