Hi, I am doing OCR application using opencv 2.4.3 in visual c++ windows forms(visual studio 2010 ultimate). I did this OCR application as a c++ console application and it works fine. But when I was converting it to windows forms it gives this error.

Error 1 error LNK2001: unresolved external symbol "public: virtual void __thiscall cv::HOGDescriptor::setSVMDetector(class cv::_InputArray const &)" (?setSVMDetector@HOGDescriptor@cv@@UAEXABV_InputArray@2@@Z)

Can someone help me to fix this error.I have no idea of correcting that error.I used same additional libraries which I used for console application here also.Thank You

WinForms do not cope well with openCV from my experience, but try to watch on the following things, which helped me out.

In order to cope between data and form, paste all your processing of openCV inside the header. It is indeed a weird way of working, but it is a Microsoft thing...
Do not add on top of your code the line using namespace cv, it will screw up your functions. Instead, call each openCV function by adding cv::FunctionName.
Check your includes again, there is a big chance you have a typo somewhere in your list.
Did you use the debug libraries in release mode or vice versa?

Get back at me if more problems arise, maybe add a link to a pastebin of your code?
