Hi im trying to run open source c++ code for tracking object using webcam and i face this problen while building the project im using visual studio 2013

The error is as following

i have these lib included in Linker>>Input >>Aditional dependencies kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib

any help please i need it for graduation project still two week only :(

Here is the code can any body tell me how to fix this class

      }

      CvLabel *labels = (CvLabel *)imgLabel->imageData + imgLabel_offset;
      unsigned char *imgData = (unsigned char *)img->imageData + img_offset;

      double mb = 0;
      double mg = 0;
      double mr = 0;
      double pixels = (double)blob->area;

      for (unsigned int r=0; r<(unsigned int)imgLabel_height; r++, labels+=stepLbl, imgData+=stepImg)

      {
        mb += ((double)imgData[img->nChannels*c+0])/pixels; // B
        mg += ((double)imgData[img->nChannels*c+1])/pixels; // G
        mr += ((double)imgData[img->nChannels*c+2])/pixels; // R
      }
    }

      /*double mb = 0;

      }
    }*/

      return cvScalar(mr, mg, mb);

}

Here is The error

  • Can you add the code (with includes & pragmas)? – A. Abramov May 09 '15 at 21:25
  • You haven't mentioned what open source code library you are using. You haven't mentioned how you are building the project, or by "the project" you mean some project included in the open source library. – Yakk - Adam Nevraumont May 09 '15 at 21:29
  • i found a code for an open source project for tracking and i need it for my project i tried to build it using vs2013 here u can find the code http://sourceforge.net/p/openvisionc/code/HEAD/tree/trunk/ – Tasneem Alshiekh May 09 '15 at 21:40
  • the files that had this error are .obj file Error 398 error LNK2001: unresolved external symbol "public: virtual int __thiscall cv::_InputArray::type(int)const " (?type@_InputArray@cv@@UBEHH@Z) C:\Users\tskhalil\Desktop\openvisionc-code-17-trunk\openvisionc-code-17-trunk\ people.obj sentry – Tasneem Alshiekh May 09 '15 at 21:42
  • here is some of my includes and pragmas but not all because the code is really big #pragma once #pragma unmanaged #include "stdafx.h" #include "header.h" #include "cvaux.h" #include "cxmisc.h" #include "highgui.h" #include #include #include this include for one of the classes that has this problem – Tasneem Alshiekh May 09 '15 at 21:48
