Look at the pimple demo in the examples or test directory. Basically you're getting some things defined twiice.
Move the implementation of template< class Archive >
void serialize( Archive& archive, unsigned int version ) to the *.cpp
and move
BOOST_CLASS_EXPORT( rs::StaticText )
to the *.cpp file as well. compile that/those *.cpp files and include in the library. This is touched upon in the manual in the part describing EXPORT.

Hi,
I'm currently trying to polymorphically serialize a class without using RTTI. I'm doing this currently in a file called StaticText.hpp:
#ifndef RS_GUI_WIDGETS_STATICTEXT_HPP
#define RS_GUI_WIDGETS_STATICTEXT_HPP
#include
#include
#include
#include
#include
#include
#include
#include
namespace rs
{
class StaticText : public Widget
{
public:
StaticText( std::string const& text );
void Update();
void Render( RenderSystem& renderer, Camera& camera );
char const* get_key() const;
private:
StaticText() {}
template< class Archive >
void serialize( Archive& archive, unsigned int version )
{
archive & boost::serialization::base_object<Widget>( *this );
std::string text;
archive & text;
m_text.reset( new Text( text ) );
}
boost::scoped_ptr<Text> m_text;
friend class boost::serialization::access;
};
}
BOOST_CLASS_TYPE_INFO(
rs::StaticText,
extended_type_info_no_rttirs::StaticText
)
BOOST_CLASS_EXPORT( rs::StaticText )
#endif // RS_GUI_WIDGETS_STATICTEXT_HPP
When I compile this into a LIB first, and then link the lib into an EXE, the linker says this (Visual Studio 2008):
gui.lib(StaticText.obj) : error LNK2005: "public: static struct boost::archive::detail::guid_initializer<class rs::StaticText> const & const boost::archive::detail::init_guid<class rs::StaticText>::guid_initializer" (?guid_initializer@?$init_guid@VStaticText@rs@@@detail@archive@boost@@2ABU?$guid_initializer@VStaticText@rs@@@234@B) already defined in main.obj
If I move the 2 macro calls into the StaticText.cpp file, everything compiles/links just fine but I end up getting an exception thrown at runtime that says "unregistered void cast".
