Hi, I'm trying to use the serialization library and was having a compile error using MSVC 2005. 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.
This is the best explanation I can give to address the issue with "const". Even if you don't buy the explanation, it's easy to avoid by using a const_cast.

Thanks, Robert First of all I didn't mean to criticize, it's just that for me things are not as clear because I'm not an expert, so it's not like I don't buy it, I just don't see it. But I'll take your word for it. So a const cast it is. If you can indulge me a little bit more, though, what I did to fix my problem, that works on the tutorial example as well, was to add: BOOST_CLASS_TRACKING(MyClass, boost::serialization::track_never) If I understand it right, I would want object tracking only if my classes somewhere in their implementation use pointers to keep track of members. I don't do that but I do use STL containers in several places. Am I liable to break serialization by using that macro? If you think I should just RTFM, please do so (I think I did, though) Thanks again for a very useful library
