Hello list,

   I need to build the projection of a point onto a line, therefore I tried 
to use Kernel::ConstructProjectedPoint_3 with no success. I paste here my 
toy-example, please, tell me if Im am doing anything wrong.



#include <CGAL/cartesian.h>
typedef CGAL::Cartesian<double> K;
typedef K::ConstructProjectedPoint_3 Cons;
typedef K::Point_3 Point;
typedef K::Line_3 Line;

int main(){
 Cons cons();
 Point a(0,0,0);
 Point b(0,0,10);
 Point c(3,5,4);

 Line l(a,b);

 Point d = cons(c);
 std::cout<< d<<std::endl;

};



And my gcc output :

pipo.C:5: error: ‘ConstructProjectedPoint_3’ in class ‘K’ does not name a type
pipo.C: In function ‘int main()’:
pipo.C:10: error: ‘Cons’ was not declared in this scope
pipo.C:10: error: expected `;' before ‘cons’
pipo.C:17: error: ‘cons’ was not declared in this scope
