Hi Luis,

could you post a simple code to demonstrate your problem?

Yes, Actually the posted code on the tutorial does: http://www.boost.org/doc/libs/1_47_0/libs/serialization/doc/tutorial.html#si... my question is why does it have to be a const object on line 51. If you take the const specifier the compilation fails (and on my program I can't make them const). I found that if you add: BOOST_CLASS_TRACKING(gps_position, boost::serialization::track_never) then the compilation succeeds, but that sort of begs the question, why the default behavior is not the most convenient one in this simple case? (Paraphrasing "Object Tracking" on the documentation) That's what I ended up doing in my code as well, but I'm not sure that's the appropriate solution, and as I mentioned, the rationale on the documentation does not seem to speak of that. Thanks for your patience with a newbie,

So I decided to try and compile "A Very Simple Case" from the tutorial, and that of course works. But then I noticed that the example serializes a const object, that sort of is rather useless, so I removed the const specifier, and I got the same error that I was getting with my program, namely: warning C4099: 'boost::serialization::static_warning_impl<false>::STATIC_WARNING' : type name first seen using 'struct' now seen using 'class'

I went googling for an answer and I found that I should look at the rationale on the docs, but the rationale (http://www.boost.org/doc/libs/1_47_0/libs/serialization/doc/rationale.html) doesn't seem at all relevant. I finally sort of guessed that I wanted was probably to modify the tracking behavior on my program (looking at the thread http://lists.boost.org/boost-users/2010/05/59107.php ). But my objects are not on the stack, so I'm not really sure. My class structure is a bit more complicated than the simple example, but my question basically is, what changes would be appropriate on the simple example so that it would compile for non-const objects?

Thanks
