为什么这段Boost R-tree代码不能编译？

Question

我使用的是boost 1.61

使用VS2015编译

下面的代码不能编译。它应该做的-我认为是适配器BOOST_GEOMETRY_REGISTER_POINT_2D_GET_SET的使用让事情变得不愉快。

你知道为什么这个不起作用或者我怎么解决它吗？

#include <boost/geometry/geometry.hpp>
#include <boost/geometry/index/rtree.hpp>
#include <boost/geometry/geometries/polygon.hpp>

#include <boost/geometry/geometries/register/point.hpp>

class wxPoint
{
public:
    wxPoint(double x, double y)
        : m_x(x),
          m_y(y)
    {
    }

    wxPoint() {}

    double  getx() const
    {
        return m_x;
    }
    double gety() const
    {
        return m_y;
    }
    void setx(double in)
    {
        m_x = in;
    }
    void sety(double in)
    {
        m_y = in;
    }
private:
    double m_x;
    double m_y;
};

BOOST_GEOMETRY_REGISTER_POINT_2D_GET_SET(
    wxPoint,
    double,
    boost::geometry::cs::geographic<boost::geometry::degree>,
    wxPoint::getx,
    wxPoint::gety,
    wxPoint::setx,
    wxPoint::sety)


typedef std::pair<wxPoint, unsigned> value;


int main()
{

    boost::geometry::index::rtree< value, boost::geometry::index::quadratic<16> > rtree;

    wxPoint p(4, 1);

    rtree.insert(std::make_pair(p, 1));

    std::vector<value> result_s;

    typedef boost::geometry::model::polygon<wxPoint> polygon_type;

    polygon_type poly;
    boost::geometry::read_wkt(
        "POLYGON((2 1.3,2.4 1.7,2.8 1.8,3.4 1.2,3.7 1.6,3.4 2,4.1 3,5.3 2.6,5.4 1.2,4.9 0.8,2.9 0.7,2 1.3)"
        "(4.0 2.0, 4.2 1.4, 4.8 1.9, 4.4 2.2, 4.0 2.0))", poly);

    rtree.query(boost::geometry::index::within(poly), std::back_inserter(result_s));

    return 0;
}

下面是更详细的compiler output

Answer 1

这是由一个错误引起的，更多信息在这里：https://svn.boost.org/trac/boost/ticket/12189和这里：https://svn.boost.org/trac/boost/ticket/12342

有几种可能的解决方法：

• 使用bg::model::point
• pass框传递多边形而不是多边形
• 将错误跟踪器页面(如上)中提到的修复程序应用于Boost 1.61
• upgrade to Boost 1.62
