Question

（从之前的问题中分离出来）。

有谁知道这里发生了什么？以下代码在MSVC中工作正常，但在intel编译器上没有。

//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);
}

最后一行（boost :: geometry :: area）是产生问题的那一行：

Answer 1

这是作为提升中的错误提交的。但Boost并没有正式支持Windows上的英特尔编译器，因此很长一段时间都无法解决。

boost :: geometry :: area无法在intel编译器上编译
