[Anton Sergunov <setosha@…>]

Wery similar #4670 but under mingw

1.43 works fine

bjam build successed, but when use boost_serializtion got

[Anton Sergunov <setosha@…>]

bjam reports many code visibility warnings in build process.

[Jim Bell <jim@…>]

Demangled, the name translates to

boost::serialization::singleton<boost::archive::detail::(anonymous namespace)::map<boost::archive::xml_iarchive> >::get_instance()

The unnamed namespace is what's causing the problem. I give the namespace a name ('extra_detail' for example), and these linker errors go away.

There are two files using them: archive/impl/archive_serializer_map.ipp and serialization/export.hpp.

See the attached patch file.

[Vladimir Prus]

This appears to make serialization unusable on mingw, therefore marking this as release blocker for now.

[Bryce Adelstein Lelbach]

This is fixed, with Jim's patch.

[Robert Ramey]

I've also checked in changes to address this. Let me know if the version on the trunk doesn't address it.
