<p><code>Translator::compile()</code> 把生成的 C++ 与 phpx 运行时源文件编译为对象文件，<code>build()</code> 再链接成最终产物。两者都委托给 <code>src/Build/NativeBuilder</code>，它负责真正派发编译/链接进程。</p>

<p>phpx misc 源（<code>typephp_fiber_generator.cc</code>、<code>typephp_helper.cc</code>、<code>typephp_main.cc</code>、<code>php_cli_process_title.c</code>、<code>ps_title.c</code>）按模式追加：embed 加 <code>typephp_main.cc</code>，bin 加 cli 标题源。</p>

<h2>并行编译</h2>
|
|
<p><code>compileWithPcntl()</code> 在 Unix/Linux/macOS 用 <code>pcntl_fork</code> 多进程编译，进度条实时刷新；无 <code>pcntl</code> 扩展时自动降级为串行。每个 <code>compileFile()</code> 调用前都会先查 <a href="pages/incremental-cache.html">增量缓存</a>，命中则跳过。</p>

<h2>build() 链接</h2>

<p><code>build()</code> 调 <code>NativeBuilder::link()</code>，Windows 模式下把 <code>.res</code> 资源文件并入目标；链接失败或产物未生成则 <code>error()</code> 退出。</p>
