title: How compatible are different versions of glibc?
body: <p>Specifically:</p>
  
  <ol>
  <li><p>Is it assured somehow that all versions of glibc 2.x are binary compatible?</p></li>
  <li><p>If not, how can I run a binary (game) on my system which has been compiled for a different version? Can I install glibc in a different folder?</p></li>
  </ol>
  
  <p>My specific problem is the compatibility between glibc 2.14 (what I have) and 2.15 (what the game wants).</p>
  
  <p>I might also get a version for glibc 2.13 but I'm not sure if that will run on 2.14.</p>
