Hi Robert, The EXPORT macros were initially inside a namespace, interesting that it compiled and linked with gcc. After fixing this I still have the same problem with Microsofts compiler. It complains about the same thing as I state below. Is there some include file that I may be missing? I can send you some code if that helps. Also where is the best place to call these macros? At the moment they are at the top in the appropriate .cpp files. Thanks, -K --- Robert Ramey wrote:

Just a guess, but are the EXPORT macros being used in side a namespace? They should be outside of any namespace.

In addition I resurrected this post to the newsgroup. It is exactly the same problem I am having:

boost 1.32, with VC7.1 I'm getting compiler errors in two unrelated translation units both dealing with std::setstd::string data members. I've gone through and ensured that i've #include'd the and headers from boost/serialization. Any ideas on what might be causing this problem? This has worked fine

Why would the 3 argument overload not be found?

Below are the (beginnings of the ) related compiler errors.

Robert,

Thank you. My project requires both linux and Win32 support. When I use this macro in win32 environment I get a compile time error. It generates a fairly long error which I can send you but here is the first few lines which are possibly the most important.

Again it is fully compiling/linking/running in Linux.

When I #ifdef the BOOST_CLASS_EXPORT(ClassName) macros I compile/link/and run. Of course base class serialzation is disable for Win32 at the moment because of this.

Thanks for any help, -K

This is addressed with the alternative BOOST_CLASS_EXPORT method. its described in the serialization documentation.

Hi all,

I have a container class that has a vector which contains several other classes. My container class has a serialize function that looks like this:

friend class boost::serialization::access; template<class Archive> void serialize (Archive &ar, const unsigned int version) { // save/load base class information ar & BOOST_SERIALIZATION_BASE_OBJECT_NVP(MyBaseClass); ar.register_type(static_cast(NULL)); ar.register_type(static_cast(NULL)); ... ar & BOOST_SERIALIZATION_NVP(m_Vector); // std::vector }

Got everything working but now an issue has come up: Someone wants to add a new class but it is not part of this package that is doing the serialzation. I want to avoid what I call "dependency hell", is there a way for

class to get registered someplace other than in this function?

For what its worth, changes have been made for 1.33 which work better with argument dependent lookup as well as two-phase lookup. I envisioned that the EXPORT marcros be in the class header after the class declaration. For export to work properly, the archive includes have to before the class heades with EXPORT in them All serialization traites macros like EXPORT must be invoke from the global namespace.

I use:

#define BOOST_NO_ARGUMENT_DEPENDENT_LOOKUP

previous to including any boost serialization headers. I'm not sure it'll solve your issues, but it did with mine with VC7.1.
