body: <p>I am using NS2.35 and Ubuntu 12.04.5 LTS </p>
  
  <p>I want to run DSR using link cache.</p>
  
  <p>I uesd "make" to recompile NS2. I got the following error: </p>
  
  <pre><code>dsr/linkcache .cc: fatal error: list.h: no such file or directory. 
  </code></pre>
  
  <p>I used locate list.h and this is its directory</p>
  
  <pre><code>/usr/src/linux-headers-3.2.0-29/include/linux/list.h 
  </code></pre>
  
  <p>That means the header file exists </p>
  
  <p>How can I solve this error ?</p>
