[Boost-users] Serialization creates huge object file

Dear Robert,

I have been using the serialization lib for a while. I already wrote 
some mail to this list as you might remember. I was quite satisfied with 
its performance and ease of use, but now there is a problem I cannot 
solve. I need to serialize/deserialize some 50 polymorphic classes, so I 
do BOOST_CLASS_EXPORT them. I put all the serialization related logic 
into one definition (.cpp) file. I only use two types of archives, 
xml_iarchive and xml_oarchive. Now, when I compile the file with Intel 
compiler v8.2 on an Itanium based machine and with debug info the result 
is a huge (>42MB) object file, which ld (the linker) simply refuses to 
link. I am quite sure that the size of the object file is the problem. I 
tried to separate the xml_iarchive related code to one .cpp file and the 
xml_oarchive related code to an another, but of course this means that 
export.hpp is included to both, which results in multiple definitions 
error when trying to link the two object files together. Could you 
suggest any solution?

Thank you very much in advance
