You're totally right. And thanks for your hint, as I think it is the right way to deal
Now the compiler doesn't complain about any of those functions.
But I still get errors I can't find explanation
Mainly, it complains when using BOOST_CONCEPT_REQUIRES to check
for adjacency_matrix implementing BidirectionalGraphConcept.
The error follows:
/usr/local/include/boost-1_38/boost/concept_check.hpp:207: error: se solicitó la conversión desde
‘boost::adj_matrix_traversal_tag’ al tipo no escalar ‘boost::bidirectional_graph_tag’
In English, it means I
asked for conversion from boost::adj_matrix_traversal_tag
to nonscalar type boost::bidirectional_graph_tag.
complains about not finding a suitable operator= when assigning vertex bundled properties
from the adjacency_matrix to an adjacency_list. This
is working when assigning from
a bidirectional adjacency_list to a directed adjacency_list and, in fact, my vertex property bundle
explicitly defined operator=, and my edge property bundle keeps the default byte-to-byte
Any hints on what might be
happenning? As I said in my last message, I can send the full error listing,
if you need it.
