With my eclipse, I have configured environment for opencv, but it appears always the problem like:

Building file: ../HelloWorld.cpp Invoking: Cross G++ Compiler arm-linux-gnueabihf-g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"HelloWorld.d" -MT"HelloWorld.d" -o "HelloWorld.o" "../HelloWorld.cpp" ../HelloWorld.cpp:1:30: fatal error: opencv2/opencv.hpp: No such file or directory compilation terminated. make: * [HelloWorld.o] Error 1

I have inserted /usr/local/include dans include paths and /usr/local/lib dans libraries paths.

And Here is my programme:

include <opencv2 opencv.hpp="">

include<iostream>

include<vector>

using namespace cv; using namespace std;

int main(int argc, char *argv[]) { cv::Mat frame; cv::Mat back; cv::Mat fore; cv::VideoCapture cap(0); cv::BackgroundSubtractorMOG2 bg; bg.nmixtures = 3; bg.bShadowDetection = false; std::vector<std::vector<cv::point> > contours; cv::namedWindow("Frame"); cv::namedWindow("Background"); for(;;) { cap >> frame; bg.operator ()(frame,fore); bg.getBackgroundImage(back); cv::erode(fore,fore,cv::Mat()); cv::dilate(fore,fore,cv::Mat()); cv::findContours(fore,contours,CV_RETR_EXTERNAL,CV_CHAIN_APPROX_NONE); cv::drawContours(frame,contours,-1,cv::Scalar(0,0,255),2); cv::imshow("Frame",frame); cv::imshow("Background",back); if(cv::waitKey(30) >= 0) break; } return 0; }
