OpenSSL libdir at `["/nix/store/<id>-openssl-3.0.13-dev/lib"]` does not contain the required files to either statically or dynamically link OpenSSL

Help

Hey there,

I’m trying to compile a project of mine made in rust, but I’m unable to compile it because openssl-sys complain that I don’t have the required files in the /nix/store/<id>-openssl-3.0.13-dev/lib path, and indeed I don’t have any other file that pkg-config :

$ ls /nix/store/dz2mjwyvs1l3vvvp5izx0xpxq1vvw075-openssl-3.0.13-dev/lib
pkgconfig

so I don’t know why the library files are not included, anyone have an idea ?
for context there is my shell.nix file :

{ pkgs ? import <nixpkgs> {} }:
pkgs.mkShell {
  nativeBuildInputs = with pkgs; [
    rustup
    rustfmt
    clippy
    gcc
    pkg-config
  ];

  buildInputs = with pkgs; [
    openssl
  ];

  shellHook = ''
    export OPENSSL_DIR="${pkgs.openssl.dev}"
    export PKG_CONFIG_PATH="${pkgs.openssl.dev}/lib/pkgconfig"
  '';
}

and the error I get when trying to compile :

I would add to shellHook:

export OPENSSL_NO_VENDOR=1
export OPENSSL_LIB_DIR="${pkgs.lib.getLib pkgs.openssl}/lib"

Oh thanks it worked! but why tough ?

That is just how env vars for it work:

  • OPENSSL_LIB_DIR is needed because in nixpkgs openssl.dev only has headers inside.
    openssl.out (current result from pkgs.lib.getLib pkgs.openssl) contains /lib with dynamic libraries.
  • OPENSSL_NO_VENDOR may not be needed if nothing enables vendored feature. But if something does it will fail in nix package, because it won’t be able to compile its own openssl.
