Hello,
I am a new CGAL user. I am trying to run this simple program using NETBEANS
but it is giving error i am not getting whether it is a CGAL configuration
problem or the program is wrong. 

*
#include <iostream>
#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
#include <CGAL/convex_hull_2.h>
#include <vector>
typedef CGAL::Exact_predicates_inexact_constructions_kernel K;
typedef K::Point_2 Point_2;

int main() {
    Point_2 points[5] = { Point_2(0,0), Point_2(10,0),
Point_2(10,10),Point_2(6,5),Point_2(4,1) };
    std::vector<Point_2> result;
    CGAL::convex_hull_2( points, points+5, std::back_inserter(result) );
    std::cout << result.size() << " points on the convex hull\n";
    return 0;
}
