Hi, I am looking an implementation of the five points algorithm in order to determine the essential matrix for a real-time application. The present version of OpenCV (2.4.4) does not include that algorithm. However, looking information about that in Google I discover that OpenCV 2.4.9 (available on github) has an implementation of the five point algorithm opencv/modules/calib3d/src/five-point.cpp. So I downloaded the source, compile it, and install it without any problem using cmake and a sudo make install.
My cmake configuration using cmake-gui:

cvconfig.h is in: /home/raul/OpenCV/build2.4.9
The problem comes when I try to compile the following code:
#include <iostream>
#include "opencv2/opencv.hpp"
using namespace std;
using namespace cv;
int main() {
cout << "Hello World" << endl;
return 0;
}
The compiler displays the following message:
In file included from example.cpp:10:0:
/usr/local/include/opencv2/opencv.hpp:47:28: error fatal: opencv2/core.hpp: No such file or directory
I don't know the reason. I have never had that problem before in OpenCV 2.4.4
Can someone tell me what should I do?
Thanks in advance
