title: Compiling STXXL on visual studio 2015
body: <p>I am trying to use STXXL map in my c++ code in visual studio 2015.</p>
  
  <p>I followed the instruction on <a href="http://stxxl.sourceforge.net/tags/master/install_windows.html" rel="nofollow">http://stxxl.sourceforge.net/tags/master/install_windows.html</a>' 
  and when I try to build the project in visual studio I get this message:</p>
  
  <p>"&lt;"hash_map">" is deprecated and will be REMOVED. Please use . You can define _SILENCE_STDEXT_HASH_DEPRECATION_WARNINGS to acknowledge that you have received this warning."</p>
  
  <p>I tried to add _SILENCE_STDEXT_HASH_DEPRECATION_WARNINGS to the preproseccor definitions but it did not help.
  It lookes like the problem comes from the file hash_map in "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include" directory.</p>
  
  <p>Does anyone know what the problem is?</p>
  
  <p>Thanks,
  Rachel.</p>
