Hmmm... I wonder if the compiler is having trouble telling the difference between edges and edges + num_edges. You might try passing edges as &edges[0] to force the compiler to treat it as a pointer. Maybe?
Unfortunately, no luck... And I didn't have this problem with adjacency_list (sorry for not saying this explicitly before!) and the same compiler (g++ v4.3.2). I guess that made me wonder if maybe this constructor does not exist? Or maybe I need to #include something more besides just "adjacency_matrix.hpp"? Hmmmm, I hope this is not too much to ask, but can you or someone else check if the sample code I posted before compiles (with the offending line uncommented)? I should compile as-is... Just to check if I'm going nuts... :-) Here it is again below [with the line commented out, so this should compile]. Thank you!
