c++ - 无法编译 CGAL 代码

Question

我无法从 CGAL docs 编译这段代码，出现以下错误:

$ g++ apply.cpp -lCGAL -I/usr/local/include -o a.out
In file included from /usr/include/CGAL/Constrained_triangulation_2.h:28:0,
                 from /usr/include/CGAL/Constrained_Delaunay_triangulation_2.h:25,
                 from apply.cpp:3:
/usr/include/CGAL/Triangulation_2.h: In instantiation of ‘class CGAL::Triangulation_2<CGAL::Epeck, CGAL::Default>’:
/usr/include/CGAL/Constrained_triangulation_2.h:47:7:   required from ‘class CGAL::Constrained_triangulation_2<CGAL::Epeck, CGAL::Default, CGAL::Exact_intersections_tag>’
/usr/include/CGAL/Constrained_Delaunay_triangulation_2.h:63:7:   required from ‘class CGAL::Constrained_Delaunay_triangulation_2<CGAL::Epeck, CGAL::Default, CGAL::Exact_intersections_tag>’

apply.cpp:12:16:   required from here
/usr/include/CGAL/Triangulation_2.h:100:48: error: no type named ‘size_type’ in ‘struct CGAL::Default’

我从 apt 安装了 libcgal-dev、libcgal-demo、g++ 和 cmake。G++版本5.4.0-6ubuntu1~16.04.9

C/C++ 不清楚版本错误，此代码示例来自 CGAL 4.12，我的库是 4.7。

我必须将我的 linux 升级到 18.04 才能以稳定的方式获得最新的 libboost 版本，然后我使用了来自 the official repository 的 libcgal 4.11|减少编译和维护库的开销。
