Hi list. I've got a question on calling map::insert using bind. What I'd like to do is to copy all members in m into m2: #include <iostream> #include <algorithm> #include <map> #include <utility> #include <boost/lambda/algorithm.hpp> #include <boost/lambda/lambda.hpp> #include <boost/lambda/bind.hpp> using namespace std; using namespace boost::lambda; int main() { map<string, int> m; map<string, int> m2; m["a"] = 1; m["b"] = 2; m2["c"] = 3; for_each(m.begin(), m.end(), bind(&map<string, int>::insert, &m2, bind(&make_pair, bind(&map<string, int>::value_type::first, _1), bind(&map<string, int>::value_type::second, _1)))); return EXIT_SUCCESS; } Unfortunately, the above code fails to compile and I have no idea why it fails. I'm using g++ and the errors are as follows: g++ map_test.cpp map_test.cpp: In function 'int main()': map_test.cpp:26: error: no matching function for call to 'bind(<unknown type>, const boost::lambda::lambda_functor<boost::lambda::lambda_functor_base<boost::lambda::action<2, boost::lambda::function_action<2, boost::lambda::detail::unspecified> >, boost::tuples::tuple<const std::basic_string<char, std::char_traits<char>, std::allocator<char> > std::pair<const std::basic_string<char, std::char_traits<char>, std::allocator<char> >, int>::* const, const boost::lambda::lambda_functor<boost::lambda::placeholder<1> >, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type> > >, const boost::lambda::lambda_functor<boost::lambda::lambda_functor_base<boost::lambda::action<2, boost::lambda::function_action<2, boost::lambda::detail::unspecified> >, boost::tuples::tuple<int std::pair<const std::basic_string<char, std::char_traits<char>, std::allocator<char> >, int>::* const, const boost::lambda::lambda_functor<boost::lambda::placeholder<1> >, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type> > >)' Any idea on this?
