Scalable RMAT Generator Example Code Not Working

[kaanolgu]

Hi,
I am trying to follow the instructions here https://live.boost.org/doc/libs/1_86_0/libs/graph_parallel/doc/html/scalable_rmat_generator.html

but the issue is that example code does not work :

#include <boost/graph/distributed/mpi_process_group.hpp>
#include <boost/graph/compressed_sparse_row_graph.hpp>
#include <boost/graph/rmat_graph_generator.hpp>
#include <boost/random/linear_congruential.hpp>

using boost::graph::distributed::mpi_process_group;

typedef compressed_sparse_row_graph<directedS, no_property, no_property, no_property,
                                    distributedS<mpi_process_group> > Graph;
typedef boost::scalable_rmat_iterator<boost::minstd_rand, Graph> RMATGen;

int main()
{
  boost::minstd_rand gen;
  mpi_process_group pg;

  int N = 100;

  boost::parallel::variant_distribution<ProcessGroup> distrib
    = boost::parallel::block(pg, N);

  // Create graph with 100 nodes and 400 edges
  Graph g(RMATGen(pg, distrib, gen, N, 400, 0.57, 0.19, 0.19, 0.05),
          RMATGen(), N, pg, distrib);
  return 0;
}

First it complained that #include <boost::graph::use_mpi.hpp> was missing and then bunch of variables needed namespace like boost::directedS but then ProcessGroup complained that it does not exist and this function template requires 4 arguments but received 2 error typedef boost::scalable_rmat_iterator<boost::minstd_rand, Graph>

I would like to get help to make this code including all missing parts to get it working.
Thank you in advance
