[Boost-users] [archive]: Problem with creating a C-Interface DLL using Serialization/Archive

Subject: [Boost-users] [archive]: Problem with creating a C-Interface DLL using Serialization/Archive

I'm writing a DLL which uses Boost for the Serialization (version 1.36.0).
Because it has to maintain in different system I want to maintain a pure C-Interface DLL.

As soon as I use the Boost-Library by activating the two lines
      boost::archive::text_iarchive ia(is);
      ia >> foo;
in the function CNwDeSerialize_Test( )
it's C++ Interface becomes exposed in my C-Interface.

Anybody got an idea why and what I can do to prevent it ?

Regards
Martin
