title: How to run Boost bcp on windows?
body: <p>I've built bcp on windows with VS14.1 and no matter what I do I keep getting the following error:</p>
  
  <p><code>std::exception Found a closing ) with no corresponding openening parenthesis.  The error occurred while parsing the regular expression fragment: '?+(([(&lt;].*&gt;&gt;&gt;HERE&gt;&gt;&gt;)?$)?'.</code> </p>
  
  <p>I tried escaping slashes via double slashes, absolute path, etc, but none of them seems to work. My boost version is 1.66</p>
  
  <pre><code>./bcp.exe D:/boost/boost_1_66_0_precompiled/boost/shared_ptr.hpp D:/boost/boost_1_66_0_precompiled
  
  ./bcp.exe D:\\boost\\boost_1_66_0_precompiled\\boost\\shared_ptr.hpp D:\\boost\\boost_1_66_0_precompiled
  
  ./bcp.exe boost/shared_ptr.hpp extract
  </code></pre>
  
  <p>Funnily enough, when I deliberately add a wrong directory, it shows "Destination path does not exist" instead.</p>
