title: How to open Linux `.so` file in Mac OS X
body: <p>My Linux <code>.so</code> file can be opened with the <code>fopen()</code> command in Ubuntu, but when I tried to open the file with the <code>fopen()</code> command in Mac OS X 10.6, it failed.</p>
  <p>The error was the file type was not recognized. How can I make a Linux library or tool work on Mac OS X 10.6 without recompilation?</p>
