Hello,

I try to catch some failures using an own user defined type (UDT), but it doesn't compile e.g. it's hardcoded to use std::sqrt:

boost_1_55_0/boost/geometry/strategies/cartesian/distance_pythagoras.hpp:165:13: error: no matching function for call to 'sqrt(core::my_type<double>)'

Indeed. We're currently fixing that. Super, when will it be finished? What are the other math function calls I didn't covered yet?

...

further, is there a way to adapt templated points?

BOOST_GEOMETRY_REGISTER_POINT_2D(point_type, point_type::coordiante_type, bg::cs::cartesian, x, y)

Yes, it is possible but we don't have a macro for that. You can specialize your traits (5 traits) manually. For templates that is often convenient, to return the corresponding coordinate type.

See c07_custom_ring_pointer_example.cpp from the examples folder. works as expected :)

Thanks, Olaf
