Hi all,

I'm trying to inherit from CGAL::Surface_mesh since it would be very
convenient for me to add some custom behavior to the meshes. I've already
followed some guidelines I found in other threads (e.g.  this one
<http://cgal-discuss.949826.n4.nabble.com/Polyhedron-vertex-descriptor-td4658859.html>
 
) but still I have a couple of compilation issues when trying to call
functions from CGAL::Polygon_mesh_processing --namely,
/is_outward_oriented()/, /volume()/ and /triangulate_faces()/.

This is my code so far:

typedef CGAL::Surface_mesh<CGAL::Simple_cartesian&lt;double>::Point_3>
CGALMesh;

namespace retQSS
{

class Mesh : public CGALMesh
{
public:
        Mesh() {};
        virtual ~Mesh() {};
};

}

namespace boost
{
        template<>
        struct graph_traits<retQSS::Mesh> :
                public boost::graph_traits<CGALMesh>
        {};

        template<>
        struct graph_traits<retQSS::Mesh const> :
                public boost::graph_traits<CGALMesh const>
        {};

        template <class Tag>
        struct property_map<retQSS::Mesh, Tag> :
                public property_map<CGALMesh, Tag>
        {};
}

...and the first compilation error I get when calling the aforementioned
functions is:

error: no type named ‘value_type’ in ‘struct boost::property_traits<bool>’

I think I could be missing some additional structs in the boost namespace.
Any help would be appreciated!

Thanks in advance,

Lucio
