I have just upgraded a project from Visual Studio 2005 to 2008 and suddenly I am getting compile errors using boost::multi_index: error C2247: 'boost::multi_index::detail::random_access_index<SuperMeta,TagList>::operator []' not accessible because 'boost::multi_index::detail::ordered_index<KeyFromValue,Compare,SuperMeta,TagList,Category>' uses 'protected' to inherit from 'boost::multi_index::detail::random_access_index<SuperMeta,TagList>' I figure that this is to do with the BOOST_MULTI_INDEX_PROTECTED_IF_MEMBER_TEMPLATE_FRIENDS define, so I tried changing #if _MSC_VER <= 1400 // 1400 == VC++ 8.0 # define BOOST_NO_MEMBER_TEMPLATE_FRIENDS #endif to #if _MSC_VER <= 1500 // 1500 == VC++ 9.0 # define BOOST_NO_MEMBER_TEMPLATE_FRIENDS #endif in visualc.hpp which fixes the compile error. Is this a bug with the visualc.hpp config in boost? I can't believe I would be the first to spot it. Has anyone else experienced this? Are member template friends actually supported in visual c++ 9? _________________________________________________________________ Download gratis emoticons voor Messenger http://www.rulive.nl/aspx/emoticons.aspx
