Hi, All, As I am working to get libtorrent working on Win32 with MSVC 7.0, I notice that BOOST_NO_MEMBER_TEMPLATES is defined by default. As a consquence, some of the functions in multi_index_container.cpp is not defined. For example, #if !defined(BOOST_NO_MEMBER_TEMPLATES) template<int N> struct nth_index { BOOST_STATIC_ASSERT(N>=0&&N<mpl::size<index_type_list>::type::value); typedef typename mpl::at_c<index_type_list,N>::type type; }; template<int N> typename nth_index<N>::type& get(BOOST_EXPLICIT_TEMPLATE_NON_TYPE(int,N)) { BOOST_STATIC_ASSERT(N>=0&&N<mpl::size<index_type_list>::type::value); return *this; } template<int N> const typename nth_index<N>::type& get( BOOST_EXPLICIT_TEMPLATE_NON_TYPE(int,N))const { BOOST_STATIC_ASSERT(N>=0&&N<mpl::size<index_type_list>::type::value); return *this; } #endif Is there anything to enable these functions when BOOST_NO_MEMBER_TEMPLATES is undef? Any suggestions? Best regards, Allen Zhao
