[Boost-users] [BGL] adjacency_list with hash_setS: bug ?

From: Johan Oudinet (johan.oudinet_at_[hidden])

Is there any example using an adjacency_list with hash_setS for
EdgeList ?

I think there is a mistake in adjacency_list.hpp:21:
// ======================
#if !defined BOOST_NO_HASH
#include <hash_set> // instead of <ext/hash_set> ?
#endif
// ======================

I'm using gcc 4.0.2 with boost 1.33.0 and I can't compile a simple
example using adjacency_list with hash_setS:

// ======================
# if defined __cplusplus
# if defined __GNUC__ && __GNUC__ >= 3
#  include <ext/hash_set>
#  include <ext/hash_map>
#  if __GNUC__ >= 4 || __GNUC_MINOR__ >= 2
namespace std {
  using ::__gnu_cxx::hash;
  using ::__gnu_cxx::hash_set;
  using ::__gnu_cxx::hash_map;
}

#   endif
#  else
#   include <hash_set>
#   include <hash_map>
#  endif /* defined __GNUC__ and __GNUC__ == 3 */
# endif /* defined __cplusplus */

#define BOOST_HAS_HASH  1          // for boost::hash_setS
#include <boost/config.hpp>
#include <boost/graph/adjacency_list.hpp>

using namespace boost;

int main()
{
  typedef adjacency_list<hash_setS, vecS, bidirectionalS> Graph;
  Graph g;
}
// ==========================
