Re: [Boost-users] [multi_index] combination with boost::tuple

Hi!

Even for the more correct typedef I get lost:

    typedef bm::multi_index_container
    <data_t,
     bm::indexed_by
     <bm::sequenced<>,
      bm::ordered_unique
      <bm::const_mem_fun<data_t, 
         std::string const &, 
         &data_t::get<0> > > > > storage_t;

 

this fails due to probably disallowed standard conversions 
(or a cobfused gcc-4.0.3): Cleaned up error message:

'&boost::tuples::cons<std::basic_string<char, std::char_traits<char>,
std::allocator<char> >, boost::tuples::cons<std::basic_string<char,
std::char_traits<char>, std::allocator<char> >, 
boost::tuples::null_type> >::get' 

is not a valid template argument for type 

'const std::string& (boost::tuples::tuple<string, string, ...>::*)()const' 

because it is of type 

'const string& (boost::tuples::cons<string, boost::tuples::cons<string,
boost::tuples::null_type> >::*)()const'

note: standard conversions are not allowed in this context
