Re: [Boost-users] [multi_index][config] Visual Studio 2009 and BOOST_NO_MEMBER_TEMPLATE_FRIENDS

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 ::operator []' not accessible because 'boost::multi_index::detail::ordered_index' uses 'protected' to inherit from 'boost::multi_index::detail::random_access_index' 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?

Hi Daniel, sorry for my taking too long to respond (next time add [multi_index] --and here possibly [config] too-- so that I'll be able to notice your post quicker). This is strange for two reasons: * MSVC 9.0 is not new and supposedly Boost.Config does already consider it --and it does not mark BOOST_NO_MEMBER_TEMPLATE_FRIENDS * Boost.MultiIndex for MSVC 9.0 seems to be running fine, without any such problem as you report, see column "msvc-9.0" at http://www.boost.org/development/tests/trunk/developer/multi_index.html Can you do the following: 1. Compile and run libs/config/test/config_test.cpp (without your local patch and, if you can afford it, using bjam --if you can't I guess a manual compile will do also): any report having to do with BOOST_NO_MEMBER_TEMPLATE_FRIENDS? 2. Can you provide a small, complete test program where the problem you've observed can be replicated? Thank you, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
