我正在使用 boost 几何库 C++。该代码在旧版本的 Eclipse（从 pythonxy 安装）中运行良好。现在我安装最新版本的 eclipse 和 Mingw (x86_64-w64-mingw32)。错误出现在函数 intersection_inserter() 和 boost::geometry::enrich_intersection_points() 中。

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

错误如下：

compare_distances目前没有在提到的行上使用，也没有在整个文件中使用。您使用的是（非常）旧版本的 Boost 吗？

可能是的，我建议升级。
