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. cl /nologo /W3 /MDd /Od /EHsc /RTC1 /GS /Gy /Zc:forScope /GR /Gd /TP /D_DEBUG /D WIN32 /D_CONSOLE /D_WINDOWS /DUNICODE /DQT_DLL /DQT_THREAD_SUPPORT /IW:\vob\abvsw\boost\1_32_0\win32\include\boost-1_32 /Iroot\abcmn\ /c build-win32-debug\...\xyz.cpp /Fobui ld-win32-debug\...\xyz.obj xyz.cpp W:\vob\abvsw\boost\1_32_0\win32\include\boost-1_32\boost\ serialization\split_free.hpp(55) : error C2780: 'void boost::archive::load(Archi ve &,T &)' : expects 2 arguments - 3 provided W:\vob\abvsw\boost\1_32_0\win32\include\boost-1_3 2\boost\archive\detail\iserializer.hpp(514) : see declaration of 'boost::archive ::load' W:\vob\abvsw\boost\1_32_0\win32\include\boost-1_3 2\boost\serialization\split_free.hpp(54) : while compiling class-template member function 'void boost::serialization::free_loader<Archive,T>::invoke(Archive &,T &,const unsigned int)' 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 --- Robert Ramey <ramey@rrsd.com> wrote:

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<SomeClass1*>(NULL)); ar.register_type(static_cast<SomeClass2*>(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 that new class to get registered someplace other than in this function?

Thanks for any help, Kauai
