[Boost-users] Overload problem with bind

From: Kerner, Jacques (jkerner_at_[hidden])

Hi,

The following test generates an error :

class Position
{
        const float	& GetX() const {...}	
        float	& GetX() {...}
};

Position myPos;
bind( &Position::GetX, ref(myPos) ) // <- does not compile

How can I avoid these ? : (with MSVC 7.1)

test.cpp(39) : error C2780: 'const
