Hello

I have a small example with brings compiler error

E:\boost\boost_1_61_0\boost\geometry\strategies\cartesian\side_by_triangle.hpp:239: Fehler: no match for 'operator>' (operand types are 'promoted_type {aka boost::geometry::model::point<double, 2u, boost::geometry::cs::cartesian>}' and 'const promoted_type {aka const boost::geometry::model::point<double, 2u, boost::geometry::cs::cartesian>}')

             : s > zero ? 1

                 ^

Compiler is mingw53.0 and msvc 2015

It's because this strategy takes CalculationType as template parameter, not PointType.
By default the CalculationType is deduced from coordinate types of passed Points.
So you should modify your code like this:

bg::strategy::side::side_by_triangle<>::apply(_p1, _p3, _pt);

Regards,
Adam
