conflicts between latest version of boost and boost geometry library (GGL)

Question

In the past, I use library GGL to write some programs. For example, the following code works well with GGL and old version of gcc. Now I update gcc to gcc4.7.1. my program appear errors during compiling. Thus, I update to the latest version of boost 1.52.1. there are still errors related to point_2d, polygon_2d etc. I found that some files like 'cartesian2d.hpp','c_array_cartesian.hpp' are missing in the latest vesion boost.

Could someone help me to analyze the following code and tell me what's the problem? Thanks a lot.

#include <iostream>

#include <boost/geometry.hpp>
#include <boost/geometry/geometries/point_xy.hpp>
#include <boost/geometry/geometries/polygon.hpp>
#include <boost/geometry/algorithms/distance.hpp>
#include <boost/geometry/geometry.hpp>

#include <algorithm> // for reverse, unique
#include <iostream>
#include <string>


typedef boost::geometry::model::d2::point_xy<double,        
boost::geometry::cs::cartesian> point_2d;
typedef boost::geometry::model::polygon<point_2d> polygon_2d;
using namespace boost::geometry;

int main() {
         std::cout << "!!!Hello World!!!" << std::endl; // prints !!!Hello World!!!
         model::d2::point_xy<int> p1(1.0, 1.0), p2(2.0, 2.0);
         point_2d x(3.0,3.0);
         std::cout << x.x();
         std::cout << "Distance p1-p2 is: " << distance(p1, p2) <<std::endl;

         float width = 100;
         float length = 100;


         polygon_2d poly;
         {
            const float coor[][2] = {
            {-350.0,-500.0}, {350,-500}, {350, 0}, {width/2.0, 0}, {width/2.0, length},
            {350, length}, {350, 1000}, {-350, 1000}, {-350, length}, {-1*width/2.0, length}, {-1*width/2.0,0},
            {-350, 0}, {-350.0,-500.0} // closing point is opening point
            };
            assign(poly, coor);
         }
            correct(poly);

         return 0;
}

The errors are as following:

Answer 1

Two changes are necessary:

1) include c_array.hpp, to adapt the 2D float array (used inside the const float[][2]) to the Boost.Geometry Point Concept:

#include <boost/geometry/geometries/adapted/c_array.hpp>

2) Use assign_points instead of assign.

assign_points(poly, coor);

Your code then compiles. Background: you were using a pre-release version (of course allowed), at release small changes were made in the interface. assign (with a range) is now called assign_points.
