Question

I am using boost geometry library C++. The code works well in the old version of Eclipse (which is installed from pythonxy). Now I install latest version of eclipse and Mingw (x86_64-w64-mingw32). the errors appear at the function intersection_inserter() and boost::geometry::enrich_intersection_points().

        typedef std::vector<polygon_2d > polygon_list;
    polygon_list v;
    intersection_inserter<polygon_2d>(square, *polygon_iterator,
                                            std::back_inserter(v));

the error is as following:

Answer 1

compare_distances is currently not used on the mentioned line, nor in the whole file. Are you using a (very) old version of Boost?

Probably yes, I advice to upgrade.
