[GRASS-dev] v.delaunay3d error

Hello Martin,

I’m getting this error when compiling your v.delaunay3d addon with CGAL 4.13:

main.cpp:106:11: error: cannot convert ‘DelaunayTriangulation* {aka CGAL::Delaunay_triangulation_3CGAL::Epick}’ to 'Triangulation {ask CGAL::Triangulation_3CGAL::Epick*}’ in assignment
T = new DelaunayTriangulation(points.begin(), points.end());

Maybe, simple type casting, but I’m not a C++ expert. Any idea?

Regards,

Huidae

Perhaps you can get some ideas from this example?

I tried static_cast, but it didn’t work (not sure why). C-style casting and reinterpret_cast worked though.
