(Split from an earlier question).
Does anyone know what’s going on here? The following code works fine in MSVC but not on the intel compiler.
//code to calculate area of convex hull from a set of points
#include <boost/geometry.hpp>
#include <boost/geometry/geometries/point_xy.hpp>
#include <boost/geometry/geometries/polygon.hpp>
#include <boost/geometry/multi/geometries/multi_point.hpp>
double convex_hull_area()
{
using boost::geometry::model::d2::point_xy;
using boost::geometry::append;
using boost::geometry::make;
//this bit works if I use a polygon instead of multi_point
boost::geometry::model::polygon<point_xy<float> > all_points_in_radius;
append(all_points_in_radius,make<point_xy<float> >(0,0));
append(all_points_in_radius,make<point_xy<float> >(3,0));
append(all_points_in_radius,make<point_xy<float> >(3,3));
append(all_points_in_radius,make<point_xy<float> >(2,1));
boost::geometry::model::polygon<point_xy<float> > hull;
boost::geometry::convex_hull(all_points_in_radius,hull);
return boost::geometry::area(hull);
}
The final line (boost::geometry::area) is the one that generates the problems:

This is filed as a bug in boost. But Boost doesn’t officially support the Intel compiler on windows, so it may not get resolved for a long time.
