Re: [Boost-users] BGL write_graphviz won't compile with listS or setS

Hi,

I'm using write_graphviz with listS and internal properties. I think  
I had a similar problem until I explicitly used the vertex_index_t  
property. The vertex index is implicit with vecS because it is the  
vertex desriptor in this case.

Cheers, Torsten
