title: fatal error: opencv/cvtypes.h: No such file or directory compilation terminated
body: <p>I am on a ubuntu 12.04 machine, with opencv 2.4.1 and gcc version 4.6.3. I have an old opencv code that I have to compile. It includes the <code>opencv/cvtypes.h</code>header file, which isn't included in this version of opencv installation. My <code>/usr/local/include/opencv</code> has only these header files:</p>
  
  <ul>
  <li>cvaux.h</li>
  <li>cv.h</li>
  <li>cvwimage.h  </li>
  <li>cxcore.hpp</li>
  <li>cxmisc.h </li>
  <li>ml.h </li>
  <li>cvaux.hpp </li>
  <li>cv.hpp </li>
  <li>cxcore.h  </li>
  <li>cxeigen.hpp </li>
  <li>highgui.h</li>
  </ul>
  
  <p>I noticed on some threads <a href="https://stackoverflow.com/questions/2401976/very-simple-application-fails-with-multiple-target-patterns-from-eclipse">[1]</a> and <a href="http://finaleanalyst.blogspot.in/2011/04/how-to-check-if-opencv-is-properly.html" rel="nofollow noreferrer">[2]</a> (dealing with opencv installation; older versions) that their <code>/usr/local/include/opencv</code> folder contained 20-21 header files. Which library has <code>cvtypes.h</code> been clubbed into? Is there a quick way of knowing such a thing, in general, without actually looking at the source code?</p>
