Having switched from boost_1_29_0 to boost_1_30_0, code that was
compiling and running now produces this error message:

I'm using Mandrake linux 9.0 with the gcc v3.22 compiler.

/home/jholle/boost_1_30_0/boost/graph/connected_components.hpp: In function
   `boost::property_traits<IndexMap>::value_type
   boost::connected_components(const Graph&, ComponentMap) [with Graph =
   boost::subgraph<boost::adjacency_list<boost::vecS, boost::vecS,
   boost::directedS, boost::GraphvizVertexProperty,
   boost::GraphvizEdgeProperty, boost::GraphvizGraphProperty,
boost::listS> >,
   ComponentMap =

/home/jholle/boost_1_30_0/boost/graph/connected_components.hpp:99: `sizeof'
   applied to incomplete type `boost::STATIC_ASSERTION_FAILURE<false>'

The code that produced this error is:
 
void
BGLLayout::FindComponents(void)
{
  typedef vector<unsigned int> Ints;
  Ints c(num_vertices(m_graph));
  connected_components(m_graph, make_iterator_property_map(c.begin(),
get(vertex_index, m_graph), c[0])); << -- line 49 (error source)
  m_componentStartVertex.clear();
  unsigned int i=0;
  for (Ints::const_iterator iter=c.begin(); iter != c.end(); ++iter,++i)
    if (m_componentStartVertex.size() <= *iter)
      m_componentStartVertex.push_back(i);
}

Note this code is largely taken from connected_components.cpp.
Can anybody tell me what is wrong here?
