Hello Delfin, This error neither depends on the way you are trying to serialize the set (list, vector, etc...) or whether serialization library is built. I had the same problem and post the report about the probable reasons of bug along with suggestion how to fix it in gmane.comp.lib.boost.devel. This issue is still unresolved. The quick workaround for you is to define BOOST_NO_ARGUMENT_DEPENDENT_LOOKUP in your project. This will force load and save methods to be defined in the serialization namespace, otherwise they would be defined in the std namespace that cause the error in linker. -- Vyacheslav E.

I am aware boost::serialization needs to be built. If I were not building it the number of linker errors would be a lot more ;)
Anyway, I built the serialization static libs (no dll seems to be available at this time) and I'm linking against it. However I got the linker error I mentioned before. It seems for some reason I cannot serialize this container (set of wstrings). I also tried changing it to a list of wstrings and got a similar unresolved external. If I try to not serialize the container my program links perfectly. Sorry my original post was in reply to a completely different one. That was my lazy way to get the email address in the "to" box. I changed the title but I forgot to delete the body of the previous email as I always do. Anyway, any help you guys can give me? I can try to come up with a small example of my problem if you guys need it.
Thanks

Hello boost,
Hi,
I started using the new serialization library. I use it to serialize a
class
which contains, among other things, a
std::set<std::basic_string<wchar_t> >
The project compiles just fine with many warnings because RTTI is not
turned
on but it compiles. However it does not link. I get this error:
Are you aware that unlike much of boost, the serialization library contains implementation files that must be built?
Sorry for the length of the error. Anyway, I am using VC++ 7.1. I
don't
know
if it matters but my project has the "Treat wchar_t as built in type"
option
turned on.
Any idea what am I doing wrong? Thanks,
BTW, you have sent your post as a reply to a post on a completely different subject.
