Re: [Boost-users] warning C4180 in VS 2005 for bind.hpp

29 Aug 2007

      Hello Adam!

I don't think the library is guilty. I think you pass some wrong parameters.
Can you please provide a sample code which produces such a warning?

With kind regards,
Ovanes

I have a large project at work. We use Visual Studio 2005 with SP 1
and
Boost 1.34.0.
    When we use boost::bind in algorithms on collections we very often get
following warning (at level 3):
J:\ThirdParty\boost_1_34_0\boost/bind.hpp(1575) : warning C4180: qualifier
applied to function type has no meaning; ignored
the detailed message is following (just an example extract from
compilation
log, sadly I was unable to produce a simple stand-alone example - but if
it
is required then I will give some more work into finding one):

One of my colleagues found a "solution" to this problem. If the
modifier
"const" is removed in one of typedef's the no warning are generated.
However
we would like a better solution since modifying the library doesn't seem a
good one.
    What to do?
