With the dynamic property code I posted previously you should be able
to just change that write_graphviz_dp call to write_graphviz(ofs, G0).
Here's some code as per my original post. With boost trunk it's
currently failing with...
include/boost/pending/property.hpp:126:5: error: no type named ‘type’
in ‘struct boost::lookup_one_property_internal’
Thanks,
Chris

Thanks Jeremiah,
I've now got something that compiles and runs, but still doesn't
include 'subgraph' clauses in the dot output and corresponding
rectangles when rendered. Interestingly if I now change back to
write_graphviz(ofs, G0) I do get some subgraph clauses, but the names
are messed up presumably since they're now being set up using dynamic
properties. Also the subgraphs still don't render in this case.
It looks like you do need to use write_graphviz (without _dp) to get
subgraphs in the output. Could you please try your original code with the
Boost trunk and see what happens? That will allow your line numbers to
match up with mine. Also, a full code example using write_graphviz would be
helpful. Thank you.
