无法在 nix 上找到 mingw32 的 pthread.h

问：

我正在尝试使用 nix 和 mingw 将使用 pthreads 的程序交叉编译到窗口。 构建抱怨缺少标头 （pthread.h），即使我设置为 buildInput。windows.pthreads

windows.pthreads似乎只复制并忽略标题。（来源libpthreadGC2.a)

win.nix：

{ pkgs ? import (builtins.fetchTarball "https://github.com/nixos/nixpkgs/archive/nixos-23.05.tar.gz") { } }:
let
  source = pkgs.writeText "main.c" ''
    #include <pthread.h>

    int main() {
      return 0;
    }
  '';
  package = { runCommandCC, fetchurl, stdenv, windows }: runCommandCC "test" {
    buildInputs = [ windows.pthreads ];
  } ''
    mkdir $out
    cd $out

    cd $out
    $CC -pthread ${source} -o main
  '';
in
  pkgs.pkgsCross.mingw32.callPackage package { }

汇编：
