Thanks Robert,
This is the error I get when I change that line to exactly what you
suggested:

The change I've suggested below should do it. This is explained

Hi,
I am experiencing difficulties in getting the Boost serialization
library to work. There seems to be an error related to object
tracking,
as I am getting BOOST_STATIC_ASSERTION_FAILURE<x>. I am trying to
figure it out using the attached test code. The documentation claims
I should
be putting a BOOST_SERIALIZATION_TRACKING() macro in my file
(presumably directly after my class definition). I did a full text
search over the entire source of the library and nowhere did this
preprocessor macro exist. There is a BOOST_CLASS_TRACKING() macro,
which I tried putting in my source with tracking_never. That seems
to have made no appreciable difference.
I have absolutely no idea what I am supposed to do. :(
Any help would be appreciated.
Thanks,
