you're correct. it's needed now. Robert Ramey Ioannis Papadopoulos wrote:

Hi,

I'm implementing my own archive (let's say my_archive) for use in Boost.Serialization.

I'm following http://www.boost.org/doc/libs/1_40_0/libs/serialization/example/demo_fast_ar...

My archive is implemented in a header file. However, I get undefined symbols unless I add the following to my source

template class boost::archive::detail::archive_serializer_map<my_archive>;

Am I missing something? Is this the correct way of doing it? I didn't have to add this prior to Boost 1.40

Thanks
