无法编译CGAL代码

Question

我无法从CGAL文档编译此代码，得到以下错误：

$ 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:

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

Answer 1

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

我不得不将我的linux升级到18.04以便以稳定的方式获得最近的libboost版本，然后我使用官方存储库中的libcgal 4.11来减少开销编译和维护库。
