  <p>Above is my full error message after including <code>boost/filesystem.hpp</code> to my project. I saw some posts which said that adding <code>-lboost_system</code> might solve this, but I have no idea where to do that in CodeBlocks!<br>
  I have already spent one day on solving this problem. Thanks for your help!</p>
