I also see a whole load of linker errors which I don't understand at present:
gcc.link.dll ..\..\..\bin.v2\libs\serialization\build\gcc-mingw-5.3.0s14\debug\libboost_serialization-mgw53-d-1_62.dll.a ..\..\..\bin.v2\libs\serialization\build\gcc-mingw-5.3.0s14\debug\binary_iarchive.o: In function `boost::serialization::singleton<boost::archive::detail::extra_detail::map<boost::archive::binary_iarchive>
::get_mutable_instance()': M:\data\boost\boost\libs\serialization\build/../../../boost/serialization/singleton.hpp:131: undefined reference to `__imp__ZN5boost13serialization16singleton_module9is_lockedEv'
The problem is that "BOOST_SERIALIZATION_DECL" expands to "__attribute__((__dllimport__))" in "singleton.hpp" when it is included from files that don't define "BOOST_SERIALIZATION_SOURCE" e.g. "binary_iarchive.cpp".
interesting observation. I'll look into this.
