Hi,
i'm new to boost and encountered the following problem with the boost graph
library:
#include "boost/graph/adjacency_list.hpp"
#include "boost/graph/adjacency_matrix.hpp"
#include "boost/graph/filtered_graph.hpp"
int main (void)
{
using namespace boost;
typedef adjacency_matrix<undirectedS> Graph;
//typedef adjacency_list Graph;
typedef filtered_graph FilteredGraph;
Graph g (5);
FilteredGraph fg (g, keep_all ());
}
This results in a lot of error messages from the compiler (see end of email),
all located in the bgl files. If i use adjacency_list (as in the commented
line above) instead of adjacency_matrix, everything's fine. I use gcc 3.3
under linux.
Is this a bug? Is there an easy way to make filtered_graph work with
adjacency_matrix? (I'd like to use adjacency_matrix because my graphs are
almost complete graphs).
Best regards,
Matthias Rupp
