Re: [Boost-users] warnings with boost::bind

Another thing that I have seen now. The compiler crashes when I want to assign it to: boost::function func=boost::bind<bool>(&A::SetData,&a); What is wrong? Hansi schrieb:

Hello,

I have a question. I use boost::bind with the following class:

class B { int data; }

class A { bool SetData(const B&){return true;}; }

now when I make somewhere the following:

A a; boost::bind<bool>(&A::SetData,&a);

I get a warning

8>D:\boost\boost_1_34_1\boost/bind.hpp(1575) : warning C4180: qualifier applied to function type has no meaning; ignored 8> D:\boost\boost_1_34_1\boost/bind.hpp(1609) : see reference to class template instantiation 'boost::_bi::add_cref' being compiled 8> with 8> [ 8> Pm=bool (__thiscall Microtec::Program::* )(const Microtec::TrackingInfo &), 8> I=1 8> ] 8> .\Program.cpp(2385) : see reference to class template instantiation 'boost::_bi::dm_result' being compiled 8> with 8> [ 8> Pm=bool (__thiscall Microtec::Program::* )(const Microtec::TrackingInfo &), 8> A1=bool 8> ]

I think it is for the const reference. Is this a problem? Is there some way to avoid it (okay the way with pragma I know)?

I use boost 1.34.1 and MSVC2005
