[Boost-users] [Serialization] Problem serialization of derived classes

From: Andreas Willich (andreas_willich_at_[hidden])
Date: 2007-01-11 12:20:00

Hi there!

I have a problem with the code in the attachment. I followed the
documentation and the examples, but I did not get the code to work. 

Gcc produces a lot of failures that something is already instantiated in
header files of the serialization library.

Has someone a idea what I am doing wrong?

My gcc version is 4.1.1-r3 and I am working on a gentoo x86 box.
