Need help linking code using Boost rtree for storing user-defined object in tree where object contains the indexable -a boost geometry box - boost

Question

I have a hard time following the C++ template and stl code of the open source boost library and hope someone can help with my code sample that tries to store a user defined object (Node) in a boost::geometry::index::rtree. The Node object contains the indexable and I am trying to define an indexable object that translates the Node to a box (retrieves the box member of Node).
I am using Visual Studio Express 2022 and Boost 1.79.0 under Windows 10.
This is the link error:
