I have a derived class from which I bind a virtual function that I did not override in this class, so I'm hoping to call the one of the parent class.
It works nice with boost (1.55), but if I switch to std::bind from C++11, it refuse to compile with
error C2100: illegal indirection 1> functional(1152) : see reference to function template instantiation '_Rx std::_Pmf_wrap<_Pmf_t,_Rx,_Farg0,_V0_t,_V1_t,_V2_t,_V3_t,_V4_t,_V5_t,>::operator ()(_Wrapper &) const' being compiled 1> with 1> [ 1> _Rx=bool, 1> _Pmf_t=bool (__thiscall Base::* )(void), 1> _Farg0=Base, 1> _V0_t=std::_Nil, 1> _V1_t=std::_Nil, 1> _V2_t=std::_Nil, 1> _V3_t=std::_Nil, 1> _V4_t=std::_Nil, 1> _V5_t=std::_Nil, 1> =std::_Nil, 1> _Wrapper=Derived 1> ]
Here is a minimum code
class Runnable { virtual bool Run() =0;};
class Base : public Runnable { bool Run() {/*do stuff*/ return true;}};
class Derived : public Base {};
Derived d;
std::function<bool()> f = std::bind(&Derived::Run,std::ref(d)); //Do not compile
std::function<bool()> f = boost::bind(&Derived::Run,boost::ref(d)); //compile
It's not a major issue, since I can stick with boost, but I would really want to know what's the difference between the two.
I've checked few questions in here but I don't think how it will be related to this.
Checked stroustrup's site too here, but I did not see anything that could explain this behaviour.
What am I missing here ?
Ps: I work with VS2012 Update 4, if this can help
