Can not compile 'adj_list_ra_edgelist.cpp'
Hi, everyone 'adj_list_ra_edgelist.cpp' is a simple example of bgl, but I can not compile it with gcc 3.4.4 on cygwin/windows xp. Following are the codes: #include <boost/config.hpp>
#include <iostream> #include <boost/graph/adjacency_list.hpp>
int main() { using namespace boost; typedef adjacency_list<vecS, vecS, bidirectionalS, no_property, property<int, edge_weight_t, property<int, edge_index_t> >, no_property, vecS> Graph;
const std::size_t n = 3; typedef std::pair<std::size_t, std::size_t> E; E edge_array[] = { E(0,1), E(0,2), E(0,1) }; const std::size_t m = sizeof(edge_array) / sizeof(E); Graph g(edge_array, edge_array + m, n); for (std::size_t i = 0; i < m; ++i) std::cout << edges(g).first[i] << " "; std::cout << std::endl;
return 0; }
The error is located in the line 28, i.e. edges(g).first[i]. I think edges(g).first has the type of adjacency_list::edge_iterator. But how can I understand 'edges(g).first[i]'? Thanks, Timothy Zhang
