Boost Geometry Compilation Errors
Trying to use the boost geometry library. Have a very simple example from the boost geometry home page int main(int argc, const char * argv[]) { double points[][2] = {{2.0, 1.3}, {4.1, 3.0}, {5.3, 2.6}, {2.9, 0.7}, {2.0, 1.3}}; bgm::polygon<bgm::d2::point_xy<double> > poly; bg::append(poly, points); boost::tuple<double, double> p = boost::make_tuple(3.7, 2.0); std::cout << "Point p is in polygon? " << std::boolalpha << bg::within(p, poly) << std::endl; … } When trying to build on my Mac I get compiler warnings: point_type.hpp No matching function for call to 'assertion_failed" coordinate_type.hpp No matching function for call to 'assertion_failed" convert_point_to_point.hpp Call to function 'get that is neither visible in the template definition or found… access.hpp Nom member named 'get in boost::geometry::core_dispatch… Is there something wrong with the boost libraries installed via macports?

Your example is not complete (no headers) so I cannot see what is missing here. The complete version below compiles for me. Registration of tuples is necessary (to indicate which coordinate system). Same for C-Arrays, if append is used like this (it can be done differently too).

Please don't top-post. This is the correct home page indeed, and contains all the include files I did mail you in the complete sample. Does it compile on your Mac? Regards, Barend
