[multi_index] boost/boost/multi_index/detail/index_base.hpp:49: error
Hi, I'm having a compiler error with gcc 3.4.4. It compiles cleanly with VC7.1 and gcc4.1. I'm using the CVS version of boost. The code is: header_decode_type and header_encode_type types dont really matter, are just member variables that are passed to header constructor. header headers::operator[](std::string const& name) const // line 57 { headers_multi_index_t::nth_index<1>::type const& index = headers_set_.get<1>(); return header(index.equal_range(name) , header_decode_handler_, header_encode_handler_); } The headers_multi_index_t is: typedef std::pair<std::string, std::string> pair; typedef mi::multi_index_container<pair , mi::indexed_by < mi::sequenced<> , mi::ordered_non_unique < BOOST_MULTI_INDEX_MEMBER(pair, std::string, first) , iless > >
headers_multi_index_t;
And the header constructor is: typedef std::pair<iterator, iterator> iterator_pair; header(iterator_pair pair , header_decode_type const& header_decode_handler , header_encode_type const& header_encode_handler); The error message is: ../src/headers.cpp: In member function `mail::header mail::headers::operator[](const std::string&) const': ../../../libs/boost/boost/multi_index/detail/index_base.hpp:49: error: `typedef struct boost::multi_index::detail::index_node_base<mail::pair> boost::multi_index::detail::index_base<mail::pair, boost::multi_index::indexed_by<boost::multi_index::sequenced<boost::multi_index::tag<mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na> >, boost::multi_index::ordered_non_unique<boost::multi_index::member<mail::pair, std::string, &std::pair<std::string, std::string>::first>, mail::iless, mpl_::na>, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na>, std::allocator<mail::pair> >::node_type' is protected ../src/headers.cpp:61: error: within this context Any help would be greatly apreaciated, best regards. -- Felipe Magno de Almeida

Hi,
I'm having a compiler error with gcc 3.4.4. It compiles cleanly with VC7.1 and gcc4.1. I'm using the CVS version of boost. The code is:
header_decode_type and header_encode_type types dont really matter, are just member variables that are passed to header constructor.
header headers::operator[](std::string const& name) const // line 57 { headers_multi_index_t::nth_index<1>::type const& index = headers_set_.get<1>(); return header(index.equal_range(name) , header_decode_handler_, header_encode_handler_); }
The headers_multi_index_t is:
typedef std::pair<std::string, std::string> pair; typedef mi::multi_index_container<pair , mi::indexed_by < mi::sequenced<> , mi::ordered_non_unique < BOOST_MULTI_INDEX_MEMBER(pair, std::string, first) , iless > >
headers_multi_index_t;
And the header constructor is:
typedef std::pair<iterator, iterator> iterator_pair;
Here. What is this "iterator" type? What index.equal_range(name) returns is a std::pair< headers_multi_index_t::nth_index<1>::type::iterator, headers_multi_index_t::nth_index<1>::type::iterator
where the iterators are not the same type as headers_multi_index_t::iterator; this is explained with more parsimony at http://boost-consulting.com/boost/libs/multi_index/doc/tutorial/basics.html#... Could this be related to the problem, or am I completely misguided? If the latter, a complete testcase reproducing the problem would be of much help.

Well, looks like it s right then...

Yes, I thought so... But looks like I'm using it right... It compiles cleanly in VC7.1 and gcc 4.1

Looks like that's not the problem
