Hi
I am new to CGAL and just wrote a program to draw and view a plane in 3D.
But when I compile the program I am getting the following error

/home/cpp/test.cpp:22: error: no match for ‘operator<<’ in ‘geomview << s1’

my simple pgm is the following

#include <CGAL/Exact_spherical_kernel_3.h>
#include <CGAL/Random.h>
#include <CGAL/Point_3.h>
#include <CGAL/IO/Geomview_stream.h>
typedef CGAL::Exact_spherical_kernel_3         Spherical_k;
typedef CGAL::Point_3<Spherical_k>             Point_3;
typedef CGAL::Sphere_3<Spherical_k>            Sphere_3;
typedef CGAL::Plane_3<Spherical_k>             Plane_3;

int main() {

 
 Point_3 p1(36,10,45);
 Point_3 p2(10,20,45);
 Point_3 p3(80,70,45);

 //Sphere_3 s4 = Sphere_3(p1, 20);
 Plane_3 s1 = Plane_3(p1,p2,p3);
  
 CGAL::Geomview_stream geomview;
 geomview << CGAL::RED;
 geomview << s1;
 
 std::cin.get();

  return 0;
}
