title: Error compiling x264 on Mac OS X
body: <p>I'm trying to compile and install the <a href="http://www.videolan.org/developers/x264.html" rel="nofollow">x264</a> H.264/AVC encoder.
  I've got <code>gcc</code> installed. But I get the 'No working C compiler found' error when I run:</p>
  
  <pre><code>./configure --enable-shared --enable-static
  </code></pre>
  
  <p>What can I do?</p>
  
  <p>The config log said:</p>
  
  <pre><code>/bin/gcc conftest.c  -Wall -I. -I$(SRCPATH) -falign-loops=16 -mdynamic-no-pic -o conftest
  clang: error: unknown argument: '-falign-loops=16' [-Wunused-command-line-argument-hard-error-in-future]
  clang: note: this will be a hard error (cannot be downgraded to a warning) in the future
  </code></pre>
