Hi,

I have a very weird error when I`m trying to use the function
linear_least_squares_fitting_2.

I`m just trying to compil the following code with the exact kernel :

#include <CGAL/Cartesian.h>
#include <CGAL/linear_least_squares_fitting_2.h>
#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>

using namespace std;
typedef CGAL::Exact_predicates_inexact_constructions_kernel K;
typedef K::Point_2      Point_2  ;
typedef K::Line_2       Line_2   ;

int main()
{
  list<Point_2> points;
  points.push_back(Point_2(1.0,0.0));
  points.push_back(Point_2(2.0,0.0));
  points.push_back(Point_2(3.0,0.0));

  Line_2 line;
  linear_least_squares_fitting_2(points.begin(),points.end(),line);

  return 0;
}

but I receive this error :
 no matching function for call to
`linear_least_squares_fitting_2(std::_List_iterator<Point_2>,
std::_List_iterator<Point_2>, Line_2&)'

I tried with CGAL && CGAL::CGALi just in case but no way...
In the .h, the function is properly defined and I tried to clean my project
too, but I still have the problem.

Does someone has an Idea about the problem I could have to use this function ?
Thank you very much.
Regards.
