Re: [Boost-users] [BGL] read_graphviz and dynamic properties

I'm not absolutely sure, but you might be able to pass along a  
boost::dummy_property_map (defined in boost/property_map.hpp) as the  
property map for node_id.  That map will not store any information.

If you don't care about any properties, and you are using Boost from  
the svn repository, then you can construct your dynamic_properties  
object with the argument '&boost::ignore_other_properties' and it  
will not complain about any properties.
