Hello

I have a small example with brings compiler error 

E:\boost\boost_1_61_0\boost\geometry\strategies\cartesian\side_by_triangle.h
pp: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);

Adam
