Hi,<br>     I have a parent class which has around 200 sub-classes. While serializing the entire hierarchy, i have lot of base class pointers and STLs of base class pointers. From the documentation, i found that if i have to serialize the polymorphic pointers, then i have to do a BOOST_EXPORT of all the relevant subclasses. But after doing that, i find my .obj file to be around 37MB. I am using the text archive in my code. When i tried the polymorphic_text_archive, the size only reduced by 3MB. <br>
     Can someone help me on how i should go about reducing the .obj file size? <br><br>Some of my questions are<br>a) One approach, i could think of is to create a virtual function in the hierarchy, which just takes the Archive and does the serialization. This would help me, because i don&#39;t need to have the BOOST_EXPORT, which increases the size of the .obj file. <br>
b) Why is BOOST_EXPORT required for polymorphic_text_archive? Since it anyway uses virtual functions instead of templates, why does it need the derived class definition.<br><br>Thanks,<br>Gokul.<br>
