Hi Elvis,

I'm now starting at your problem. The code below indeed does not run:2

>     /* A line string. */
>     linestring_2d s;
>     s.push_back(make<point_2d>(0.0, 10.0));
>     s.push_back(make<point_2d>(20.0, 10.0));
>
>     /* Clip the linear ring with the linestring. */
>     std::vector<linestring_2d> r;
>     intersection_inserter<linestring_2d>(t, s, std::back_inserter(r));
> The error I'm getting is:

> boost-geometry/boost/geometry/algorithms/within.hpp:336: error:

Indeed this is not running; it will be implemented some moment; however 
the problem you were interested in was getting intersection points 
between a polygon and a linestring, including their direction, right?
