ok thank
there's a way to know if my map is read-only or to converte them in writable??
I write only  the command "boost::property_map<Triangulation,boost:edge_weight_t>::type ...",  and I not define the map, I think that Cgal triangulation is my map (graph), or not??
Sorry but it's the first time that I use CGAL and boost.

Bye

Maybe your property map is read-only. Remember that the Boost Property Map
library defines four concepts:
  ReadablePropertyMap
  WritablePropertyMap
  ReadWritePropertyMap
  LvaluePropertyMap
(see http://www.boost.org/libs/property_map/property_map.html).

If your property map is not model of the WritablePropertyMap concept, you
cannot use put with it.
