Hi Geometry team, nice to meet some of you (Adam, Barend, Menalaos) at Meeting C++ last year! I started doing projection transformations for the first time recently and found some compilation errors (using gcc or clang) when I include "project_inverse_transformer.hpp". Specifically, this is the amusingly helpful output from clang 3.6: project_inverse_transformer.hpp:63:9: error: no member named 'convert' in namespace 'boost::geometry::detail'; did you mean 'concept'? and project_inverse_transformer.hpp:63:9: error: no template named 'point_to_point' in namespace 'boost::geometry::concept'; did you mean 'detail::conversion::point_to_point'? Are these just known unfinished features? Thanks, cheers. Jeremy
