我无法从CGAL docs编译此代码,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:

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,这个代码示例来自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the official repository中的libcgal 4.11来减少编译和维护库的开销。
