Pasar de impulso :: unen a std :: bind: Error de compilación

Question

que tenía este edificio código y funcionando perfectamente:

boost::function<void(string)> bar = boost::bind(&Bar::BarHandler, this, _1); 

//Somewhere else in Bar.cpp 
void Bar::BarHandler(std::string message){ 
    //Do stuff 
} 

Cuando felizmente cambiado boost por std en el código anterior, empecé a recibir este error (mi compilador es Visual Studio 2010 SP1):

¿Qué está pasando? ¿Tal vez debería eliminar las referencias a los encabezados de Boost?

Answer 1

es probable que necesite para incluir <functional> y explícitamente utilizar el espacio de nombres de marcadores de posición para la Edición _1

using namespace std::placeholders; 

: Como se ha señalado en los comentarios, también necesitaría para eliminar las cabeceras de impulso que traen los marcadores de posición en el espacio de nombres global.
