Hi guys,

I have just started to use boost::serialization to serialize a complex data structure in a VS2005 MFC project.
I'm still very unfamiliar with boost but i need to get this done by then end of the day.
I ran into a couple of linker errors during compilation:

error
 LNK2005: "public: unsigned int __thiscall 
std::basic_string<char,struct std::char_traits<char>,class 
std::allocator<char> >::size(void)const " 
(?size@?$basic_string_at_DU?$char_traits_at_D@std@@V?$allocator_at_D@2@@std@@QBEIXZ)
 already defined in msvcprt.lib(MSVCP80.dll)    libcpmt.lib

Hi,
Your first error looks like your are trying to link both static (libcpmt.lib) and dynamic (msvcprt.lib) CRTs at the same time. This dependency could be hidden in a third party lib, including boost. Make sure that everything in the same module (dll, exe) links to the same version.

Adding /verbose link usually helps.
Regards,
David.
