[Boost-users] boost.function and boost:bind in MSVS2005

Hi there.

I'm using boost.function and boost:bind to point to Member function
this way:

class ModuleRegister
        {
        public:
                ModuleRegister(void);
                ~ModuleRegister(void);

                typedef boost::function1< std::string, std::map<std::string,std::string> > HEFunc;
                void RegisterClassMember(std::string & name, const HEFunc & f);

        };

class News : public BaseModule
        {
        public:
                News(void);
                ~News(void);

                std::string show(std::map<std::string,std::string> bb);
        };

        than in other class

        void IParser::PrepareModules()
        {
                ModuleRegister::HEFunc f;
                 f = boost::bind(&News::show, &NewsObj, _1);
                MRegister.RegisterClassMember(std::string("News.show"),f);
        }

        and I get
1>IParser.obj : error LNK2005: "union boost::detail::function::any_pointer __cdecl boost::detail::function::make_any_pointer(void *)" (?make_any_pointer_at_function@detail_at_boost@@YA?ATany_pointer_at_123@PAX_at_Z) already defined in Main.obj
1>IParser.obj : error LNK2005: "bool __cdecl boost::detail::function::has_empty_target(...)" (?has_empty_target_at_function@detail_at_boost@@YA_NZZ) already defined in Main.obj

IParser.h is actually included in Main.h

and #include "boost/function.hpp" is in ModuleRegister.h which is
included in IParser.h

can't handle this problem
