Re: [Boost-users] [PBGL] Betweenness centrality and named vertexes

Hi, unfortunately, I can't help you directly with that one as I have no MPI installed. I compared your code to one of my attempts to work with brandes_betweenness_centrality and I could not find anything that would make me say "Change this, and it should work". However, the documentation of brandes_betweenness_centrality says for the centrality_map: The value type of this property map should be a floating-point or rational type. I don't know if you already tried that out. When I eliminate the MPI-parts and simply define adjacency_list , it compiles just fine. Also the vector<int> seems not to be a problem, although it might be for your results later on. What is interesting me though is, why you define an internal_vertex_name, when you already have it as a bundled property? Best, Cedric On Saturday, 27. November 2010 11:07:05 Carmine Paolino wrote:

Hello,

I'm trying to use `brandes_betweenness_centrality` with named vertexes but so far I haven't managed to get it working.

These are the two approaches I tried:

1. passing an iterator_property_map on the vertex_index: https://gist.github.com/f02f18f30f0eef146a58#file_betweenness_named_graph. cpp

2. passing a property_map on a float inside the vertex: https://gist.github.com/f02f18f30f0eef146a58#file_betweenness_named_graph2 .cpp

And these are the compile logs for the first file: clang: https://gist.github.com/f02f18f30f0eef146a58#file_compile_clang.log gcc:https://gist.github.com/f02f18f30f0eef146a58#file_compile_gcc.log

and the second file: clang: https://gist.github.com/f02f18f30f0eef146a58#file_compile_clang2.log gcc: https://gist.github.com/f02f18f30f0eef146a58#file_compile_gcc2.log

What I'm doing wrong?
