[boost] [serialization] BOOST_CLASS_EXPORT

Hello, I am using the CVS version tagged RC_1_34_0. I put all the BOOST_CLASS_EXPORT statements into a header file that also contains all the serialization functions. This header is included by two separate .cpp files, each of which implements the loading and saving of archives for a different subset of the classes that can be serialized. These are all compiled into a single DLL. All of this compiles under VC8.0 (but I have not yet verified that it runs properly). But when linking with gcc (in Linux), I get multiple definition errors when linking. What's the best way to deal with this? (assuming that this is a problem that you recognize and know how to fix) Deane
