title: Linker error in OpenCV with Visual Studio
body: <p><br>
  I am trying to do some image rectification using OpenCV .I got some code from <a href="http://permalink.gmane.org/gmane.comp.lib.opencv/14644" rel="nofollow">http://permalink.gmane.org/gmane.comp.lib.opencv/14644</a> but the problem is the moment I include CvCalibFilter in my code it starts to give me linker error.More precisely this is what it says :-</p>
  
  <blockquote>
    <p>: error LNK2001: unresolved external symbol "public: virtual __thiscall CvCalibFilter::~CvCalibFilter(void)" (??1CvCalibFilter@@UAE@XZ)</p>
  </blockquote>
  
  <p>I saw some posts of people having the same problem but could not find a solution anywhere.Can someone help?
  Thanks!</p>
  
  <p>P.S. I installed OpenCV to work with Visual Studio as mentioned in the tutorial.</p>
