I try to compile a opencv program I added all the libraries nelom but I dont seem to have them on my libraroes just oneslike /usr/lib/x86_64-linux-gnu/libopencv_highgui.so what do I add to my

gccc++ linker? make all Building target: peopleFinder Invoking: GCC C++ Linker g++ -L/usr/include/opencv -L/usr/lib/x86_64-linux-gnu/ -L/usr/local/lib -o "peopleFinder" ./peopleFinder.o -lopencv_core\ \ opencv_imgproc\ \ opencv_highgui\ \ opencv_ml\ \ opencv_video\ \ opencv_features2d\ \ opencv_calib3d\ \ opencv_objdetect\ \ opencv_contrib\ \ opencv_legacy\ \ opencv_flann /usr/bin/ld: cannot find -lopencv_core opencv_imgproc opencv_highgui opencv_ml opencv_video opencv_features2d opencv_calib3d opencv_objdetect opencv_contrib opencv_legacy opencv_flann collect2: error: ld returned 1 exit status make: * [peopleFinder] Error 1

I have some code :

enter code here #include <highgui.h> #include <iostream> #include <stdio.h> #include <cv.h>

    using namespace std;
    using namespace cv;
    using namespace std;

    int main()
    {
        cvNamedWindow("people detecting camera",1);
        CvCapture* capture = cvCaptureFromCAM(CV_CAP_ANY);
        CascadeClassifier peopleDetector;
        peopleDetector.load("src/people.xml");
        if(peopleDetector.empty())


and i get these errors

undefined reference to `cvNamedWindow'
undefined reference to `cvCreateCameraCapture'
undefined reference to `cv::CascadeClassifier::CascadeClassifier()'
undefined reference to `cv::CascadeClassifier::load(std::string const&)'
undefined reference to `cv::CascadeClassifier::empty() const'

Now from what I have all the imclude directories added does this mean the compiler cannot find the openCV library
