提升幾何圖形交集 <polygon_2d> 不起作用

Question

我正在使用升壓幾何庫C ++。 該代碼在舊版本的Eclipse（從pythonxy安裝）中運行良好。 現在，我安裝了最新版本的eclipse和Mingw（x86_64-w64-mingw32）。 錯誤出現在函數intersection_inserter（）和boost :: geometry :: enrich_intersection_points（）處。

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

錯誤如下：

Answer 1

當前未在提到的行上或整個文件中使用compare_distances 。 您是否正在使用（非常舊版本的）Boost？

可能是的，我建議升級。
