Hi Boost, I'm using GCC 4.7 on C++-11 mode. I have a std::unordered_map container which I'd like to serialise. Is there any support for this scenario? I can see that Jim Bell has provided some patches for TR1 serialisation: https://svn.boost.org/trac/boost/ticket/5265 Unfortunately these patches don't appear to take into account C++-11 - at least they don't work out of the box for me and the fix doesn't seem entirely obvious to me. I couldn't find the email discussion of these patches, so I may have missed any follow ups. Any pointers in the right direction are greatly appreciated. Many thanks for your time. -- So young, and already so unknown -- Pauli blog: http://mcraveiro.blogspot.com
