Hello,
I have a problem with "intersection" function. This is my class:

template <class Traits_, class AppKernel_>
class my_class
{
public:

  typedef Traits_                                   Traits_2;
  typedef AppKernel_                                Approx_kernel;
 
  typedef typename Approx_kernel::Point_2           App_point_2;
  typedef typename Approx_kernel::Segment_2         App_segment_2;
  ...
}

and I have these in one one of my functions (I have put somethings in segList and app_bound_segs list and they have no problem):

typename std::list<App_segment_2>::const_iterator      sit1, sit2;
std::list< App_point_2 > interPoints;
std::list< App_segment_2 >       app_bound_segs, segList;
interPoints.clear();

for ( sit1 = segList.begin(); sit1 != segList.end(); sit1++ )
  for ( sit2 = app_bound_segs.begin(); sit2 != app_bound_segs.end(); sit2++ )
     interPoints.push_back( CGAL::intersection( sit1, sit2 ) );
 
 
when I compile, it says:
error C2784: 'CGAL::Object CGAL::intersection(const CGAL::Triangle_2<R_> &,const CGAL::Iso_rectangle_2<R_> &)' : could not deduce template argument for 'const CGAL::Triangle_2<R_> &' from 'std::list<_Ty>::_Const_iterator<_Secure_validation>'

 

what does the error mean? I read in manual that
Object intersection( Type1<Kernel> obj1, Type2<Kernel> obj2);

 

so what is the problem?
Thanks,
