Builds OK but FAILS at runtime , at run time I get a C++ exception BEFORE main() in basic_serializer_map.cpp around the line 48:
'archive_exception::multiple_code_instantiation with the message "code instantiated in more than one module - polymorphic_base"'
This would indicate that the serialization for polymorphic_base is included in BOTH the mainline and the DLL. Check that the serialization function is NOT an inline definition. the polymorphic_base.cpp should only be needed when compiling the DLL. option 1 include serialization definition for polymorphic_base in my_serialization.dll option 2 include serialization definition for polymorphic_base in it's own dll.
4. serialization files in a separate dll. Both the main executable and my dll link with the static version of the serialization library:
main.exe my_serialization.dll boost_serialization.lib
my_serialization.dll boost_serialization.lib
Builds OK but FAILS at runtime while trying to serialize with the following exception thrown in oserializer.hpp(line 424):struct polymorphic::save():
'unregistered void cast class polymorphic_derived1<-polymorphic_base in function 'int __cdecl main(int,char *[])''
This is probably failing due to the compiler stripping out code not explicitly referred to. Since it's not referrred to, the linking doesn't include it from the library. Robert Ramey
