title: Issue with archive which is not the architecture being linked (x86_64) in C
body: <p>When I run make on this program I am trying to build, I get these warnings:</p>
  
  <pre><code>ld: warning: ignoring file ../lib/libiptools.a, file was built for archive which is not the architecture being linked (x86_64)
  ld: warning: ignoring file ../lib/libmpeg.a, file was built for archive which is not the architecture being linked (x86_64)
  </code></pre>
  
  <p>And then it obviously fails to compile with this:</p>
  
  <pre><code>ld: symbol(s) not found for architecture x86_64
  collect2: ld returned 1 exit status
  make: *** [iptool] Error 1
  </code></pre>
  
  <p>I am just having a hard time figuring out how to alter my make file and compile properly for this as I am unfamiliar with archives. Any advice is appreciate since I am sure I am missing something simple. I am using Mac OS X Mountain Lion.</p>
