In range/detail/begin.hpp: template<> struct range_begin<array_> { template< typename T, std::size_t sz > static T* fun( T BOOST_ARRAY_REF[sz] ) BOOST_ARRAY_REF is not defined anywhere I can see. This should probably be: template< typename T, std::size_t sz > static T* fun( T BOOST_RANGE_ARRAY_REF()[sz] ) ---------------------------------- In range/detail/end.hpp: template<> struct range_end<char_array_> { template< typename T, std::size_t sz > static std::size_t fun( T BOOST_RANGE_ARRAY_REF()[sz] ) { return boost::range_detail::array_end( array ); } }; template<> struct range_end<wchar_t_array_> { template< typename T, std::size_t sz > static std::size_t fun( T BOOST_RANGE_ARRAY_REF()[sz] ) { return boost::range_detail::array_end( array ); } }; The return types of these two functions are wrong. They should be T* instead of std::size_t. -- Eric Niebler Boost Consulting www.boost-consulting.com
