title: fatal error: boost/chrono.hpp: No such file or directory
body: <p>This question has been asked many times in different ways, but none of the solutions have  solved my problem.</p>
  
  <p>Environment : Ubuntu 12.04, Eclipse-cdt </p>
  
  <ol>
  <li>Boost library 1.55.0 (thread, chrono, date_time and system) is at <strong>/boost</strong></li>
  <li>Included the same path in Project Properties -> C/C++ General -> Paths and Symbols -> Includes -> Include directories</li>
  <li>Included <strong>/boost/stage/lib</strong> in Project Properties -> C/C++ General -> Paths and Symbols -> Includes -> Library Paths</li>
  <li>Linked all libraries e.g. <strong>/boost/stage/lib/libboost_chrono.a</strong> in <strong>_LDADDS</strong></li>
  <li>Used <strong>-I</strong> in <strong>_CPPFLAGS</strong> to give <strong>/boost</strong> header files</li>
  </ol>
  
  <p>Am I missing something?</p>
