<h3 dir="auto">Describe the problem</h3>
<p dir="auto">I'm following the instructions for Mac source installation (<a href="https://www.tensorflow.org/install/install_sources" rel="nofollow">https://www.tensorflow.org/install/install_sources</a>, "Prepare environment for Mac OS" and then "Build the pip package") but I'm running into issues with BoringSSL.</p>
<p dir="auto">It looks like the <code class="notranslate">-Wunused-but-set-parameter</code> and <code class="notranslate">-Wno-free-nonheap-object</code> flags are causing the compilation to fail, since <code class="notranslate">clang</code> does not support them.</p>
<p dir="auto">Expected behavior: The build system should detect this and handle it correctly, eg. by not using the un-available flags</p>
<p dir="auto">Actual behavior: Error / fails to build</p>
