Cannot make 'point_on_surface' compile

[JD31]

I don't manage to use 'point_on_surface'. (Maybe I don't use the right method??)

    typedef boost::geometry::model::point<double, 2, boost::geometry::cs::cartesian> BGPoint;
    boost::geometry::model::polygon<BGPoint> poly;

    // ...

    BGPoint point;
    boost::geometry::point_on_surface(poly, point);

It does not build due to a static assert :

In template: static assertion failed due to requirement 'boost::geometry::detail::static_assert_check<false, boost::geometry::cartesian_tag>::value': Not implemented for this type.

in instantiation of template class 'boost::geometry::strategy::side::services::default_strategyboost::geometry::cartesian_tag' requested here in instantiation of function template specialization 'boost::geometry::point_on_surface<boost::geometry::model::polygon<boost::geometry::model::point<double, 2, boost::geometry::cs::cartesian>>, boost::geometry::model::point<double, 2, ...

Sorry, I cannot reproduce it. Could you please provide more information? That is, all the code you tried to compile. For example what headers are you including?

[JD31]

Here is a Goldbolt link to an example that does not compile and with all the includes I use (lot are not necessary but it is representative of my build context):

You have to include also

#include <boost/geometry/strategies/strategies.hpp>

alternatively replace all boost geometry includes by #include <boost/geometry.hpp>.

Right. Thank you.
