Re: [Boost-users] graphviz compile problem

Hi Jean,

The vertex descriptor of a graph is not, *in general*, required to be 
something
that one can print with an ostream. The vertex_index, however, is just 
an
integer, which can be printed via ostream.

However, to use this, your graph must have an internal vertex_index 
property.
Does it have this?

Cheers,
Jeremy
