Hi everyone,

I'm a french student in the last year in advanced engineering study.
I have to realize a project, I need to use boost, but I have a really
strange error :

error LNK2019: symbole externe non résolu "void __cdecl
boost::throw_exception(class std::exception const &)"
(?throw_exception_at_boost@@YAXABVexception_at_std@@@Z )
référencé dans la fonction "public: void __thiscall
boost::function0<void,class std::allocator<void> >::operator()(void)const "
( ??R?$function0_at_XV?$allocator_at_X@std@@@boost@@QBEXXZ) MessageManager.obj

It happens on :

void
MessageManager::listen()

{

    boost::function< void(void) > func;

    func = boost::bind( &MessageManager::run, this );

    thrd_listen = new boost::thread ( func ); // this line gives the error.

}

and :

void
MessageManager::run()

{

    stop = false;

    string message;

    dispatcher = new DispatchedMessage(this, eventManager);

    boost::function< void(void) > func;

    bool status = SendMessage(new ApplicationNameMessage("HL2", 0));

    if( !status )

        stop = true;

    while (!stop)

    {

        message = ReceiveMessage();

        if( message.length() > 0 )

        {

//Thread pour dispatcher

            func = boost::bind( &DispatchedMessage::analyser, dispatcher,
message );

            boost::scoped_ptr<boost::thread> thrd_dispatch (
newboost::thread ( func )); //
this line gives the error.

        }

        else

        {

            cout<<"Pb : Déconnexion client !"<<endl;

            stop = true;

            closesocket(csock);

            WSACleanup();

        }

    }

}

I'm a beginer in using boost ant that code has been written by my friend who
works on the project with me.

Thanks for your help !
