Initializing a polygon in boost::geometry

Question

I am new to the generic geometry library that is proposed for inclusion with boost: ``` http://geometrylibrary.geodan.nl/ ``` I have two vectors `vector Xb, Yb` that I am trying to create a polygon from. I am trying to get something along the lines of the following code snippet: ``` polygon_2d P; vector::const_iterator xi; vector::const_iterator yi; for (xi=Xb.begin(), yi=Yb.begin(); xi!=Xb.end(); ++xi, ++yi) P.push_back (make(*xi, *yi)); ``` The above code does not work, complaining that `P` does not have a `push_back` member function. How do I initialize the polygon from points that have coordinates `vector Xb,vector Yb`?

Accepted Answer

```
append(P, make<point_2d>(*xi, *yi));
```
