Hello all, I've been using the serialization library for a while now. Because of the run-time module loading aspect of our project, serialization has to be available through virtual functions and we do this by wrapping calls to boost serialization using poylmorphic archive types. In general, this has worked well. We'd like to start using the 1.35 branch because we want access to Boost.mpi as well. Rebuilding the code against 1.35 works fine and doesn't require any changes. However, as soon as we try running any code, we get the following missing symbol problem (this is happening when run-time loading a library that links against boost_serialization): undefined symbol: _ZN5boost7archive6detail27archive_pointer_iserializerINS0_27polymorphic_binary_iarchiveEEC2ERKNS_13serialization18extended_type_infoE Any ideas on what could be going on here? I'm running revision 41959 built with GCC 3.4. Regards, Chris Hamilton
I would be interesting to know if the same occurs with text archives. Robert Ramey Chris Hamilton wrote:

The same thing occurs, with the corresponding missing symbol: _ZN5boost7archive6detail27archive_pointer_iserializerINS0_25polymorphic_text_iarchiveEEC2ERKNS_13serialization18extended_type_infoE

I am interested in addressing this. Could you send a small example. Also you might run a couple of tests you isolate what the behavior is related to. a) binary vs text - you ran this test and so it doesn't seem related to archive type b) polymorphic vs non-polymorphic archive type. c) exported vs non-exported serialization type.
