title: How to install multiple versions of glibc?
body: <p>I have a glibc version 2.19 on ubuntu installed. I would also like to install 2.3.4 version along with 2.19 on my machine. </p>
  
  <p>By default, all the program should use 2.19 but only specific program should use 2.3.4. <br><br>
  The two questions are:</p>
  
  <ol>
  <li>How should I install the 2.3.4 at particular location, say /usr/glibc2.3.4?</li>
  <li>How should I specify particular program to use the 2.3.4 version?</li>
  </ol>
