VS2015(C++14 partly) cannot use this geometry

[xiaofeiyun123]

Is there a way to use boost.geometry closest_points in VS2015(C++14 partly)?
Or other possible library has similar function with boost.geometry closest_points?
Because I indeed need to develop in the enviroment of VS2015.

Compile error when build with VS2015
#if defined(BOOST_NO_CXX14_CONSTEXPR)
#error "Use C++14 or higher to compile Boost.Geometry, or use Boost 1.72 or lower."
#endif

Compile passed when build with VS2017

C++14 is the minimal requirement.
If that is not supported - then you have to use Boost 1.72 or lower.
