sorry for disturbing, i think you mean test example given on 
http://www.boost.org/doc/libs/1_39_0/libs/graph/example/transitive_closure.cpp

Yes i tried this example but it is not using this method.

void transitive_closure(const Graph& g, GraphTC& tc, G_to_TC_VertexMap g_to_tc_map, VertexIndexMap index_map)


Thanks again

I have suggested you look at the testcase -- did you do that?
