I am trying just a basic face recognition program with OpenCV2.4 with the following code:

#include "stdafx.h"
#include <iostream>
#include <string>

//include opencv core
#include "opencv2\core\core.hpp"
#include "opencv2\contrib\contrib.hpp"
#include "opencv2\highgui\highgui.hpp"
#include "opencv2\objdetect\objdetect.hpp"
#include "opencv2\opencv.hpp"

//file handling
#include <fstream>
#include <sstream>

using namespace std;
using namespace cv;

static void dbread(const string& filename, vector<Mat>& images, vector<int>& labels, char separator = ';'){
    std::ifstream file(filename.c_str(), ifstream::in);

    if (!file){
        string error = "no valid input file";
        CV_Error(CV_StsBadArg, error);
    }

    string line, path, label;
    while (getline(file, line))
    {
        stringstream liness(line);
        getline(liness, path, separator);
        getline(liness, label);
        if (!path.empty() && !label.empty()){
            images.push_back(imread(path, 0));
            labels.push_back(atoi(label.c_str()));
        }
    }
}



void fisherFaceTrainer(){
    /*in this two vector we put the images and labes for training*/
    vector<Mat> images;
    vector<int> labels;

    try{        
        string filename = "mycsv.txt";
        dbread(filename, images, labels);

        cout << "size of the images is " << images.size() << endl;
        cout << "size of the labes is " << labels.size() << endl;
        cout << "Training begins...." << endl;
    }
    catch (cv::Exception& e){
        cerr << " Error opening the file " << e.msg << endl;
        exit(1);
    }


    Ptr<FaceRecognizer> model = createFisherFaceRecognizer();

    model->train(images, labels);

    int height = images[0].rows;

    model->save("fisherface.yml");

    cout << "Training finished...." << endl;
}


int _tmain(int argc, _TCHAR* argv[])
{
    fisherFaceTrainer();
    //int value = FaceRecognition();
    return 0;
}

When I run this, I get this error(no-symbols-loaded-for-opencv_contrib2410): no-symbols-loaded-for-opencv_contrib2410

*Right click on image>>open image in new tab>>to check the bigger size

Thanks for helping

OpenCV 2.4 is 2.4.11... is it that the problem? search for the dll, is it on your computer? then search in the linking part, have you linked it correctly?

Other thing: do you find win 10 (in the actual beta mode) better then the 7? Shall I switch to it? :p

  • if you want to debug the opncv library code, you need to rebuild opencv from src, the pdb files nessecary are not supplied with the binary packs

  • it looks like you're trying to debug a release version ?

Just like @berak said, debug symbols are not included in the standard OpenCV downloads because they clog up the package. If you really want debugging options, then you need to rebuilt the library yourself.
