Question

当尝试使用新版本的boost 1.65.1编译我的项目时，我收到以下错误：

C:\Users\twozn\Dev\soundtoolkit\stk\libraries\boost/geometry/strategies/distance.hpp(101): error C2664: 'int boost::mpl::assertion_failed<false>(boost::mpl::assert<false>::type)': cannot convert argument 1 from 'boost::mpl::failed ************(__cdecl boost::geometry::strategy::distance::services::default_strategy<boost::geometry::point_tag,boost::geometry::segment_tag,boost::geometry::model::point<float,2,boost::geometry::cs::cartesian>,boost::geometry::model::point<float,2,boost::geometry::cs::cartesian>,boost::geometry::cartesian_tag,boost::geometry::cartesian_tag,void>::NOT_IMPLEMENTED_FOR_THIS_POINT_TYPE_COMBINATION::* ***********)(boost::mpl::assert_::types<Point1,Point2,CsTag1,CsTag2>)' to 'boost::mpl::assert<false>::type'

1>            Point1=boost::geometry::model::point<float,2,boost::geometry::cs::cartesian>,
1>            Point2=boost::geometry::model::point<float,2,boost::geometry::cs::cartesian>,
1>            CsTag1=boost::geometry::cartesian_tag,
1>            CsTag2=boost::geometry::cartesian_tag
1>        ]

由行

触发

std::vector<Value> results;
rtree.query(boost::geometry::index::nearest(Point(p.x, p.y), 1), std::back_inserter(results));

上面rtree定义为

using Point = boost::geometry::model::point<float, 2,boost::geometry::cs::cartesian>;
using Segment = boost::geometry::model::segment<Point>;
using Value = std::pair<Segment, size_t>;
boost::geometry::index::rtree<Value, boost::geometry::index::rstar<16>> rtree;

触发的断言是（boost / geometry / strategies / distance.hpp）：

template
<
    typename GeometryTag1,
    typename GeometryTag2,
    typename Point1,
    typename Point2 = Point1,
    typename CsTag1 = typename cs_tag<Point1>::type,
    typename CsTag2 = typename cs_tag<Point2>::type,
    typename UnderlyingStrategy = void
>
struct default_strategy
{
    BOOST_MPL_ASSERT_MSG
        (
            false, NOT_IMPLEMENTED_FOR_THIS_POINT_TYPE_COMBINATION
            , (types<Point1, Point2, CsTag1, CsTag2>)
        );
};

这与Boost 1.64.0一起编译并正常工作。编译器是Visual Studio 2017 Update 1.这里有什么问题？

无法访问MSVC，我可以/猜测/您需要包含更多标头。可能是他们间接包含在Boost 1.64.0中。

看看你是否可以编译以下自包含的例子：

<强> Live On Coliru

#include <boost/geometry/geometry.hpp>
#include <boost/geometry/core/coordinate_system.hpp>
#include <boost/geometry/geometries/segment.hpp>
#include <boost/geometry/index/predicates.hpp>

using Point   = boost::geometry::model::point<float, 2,boost::geometry::cs::cartesian>;
using Segment = boost::geometry::model::segment<Point>;
using Value   = std::pair<Segment, size_t>;

int main() {
    boost::geometry::index::rtree<Value, boost::geometry::index::rstar<16>> rtree;

    std::vector<Value> results;
    rtree.query(boost::geometry::index::nearest(Point(1, 2), 1), std::back_inserter(results));
}

使用Visual Studio 2017提升1.65.1几何距离策略编译错误
