I have just installed Service Pack 1 for VS2005, and am now getting a warning in some code using lambda::bind. There wasn't a warning previously, but I don't know if the issue is due to an update to the C++ standard library, a legitimate warning that they weren't flagging before, or a spurious warning. It looks like the issue is that I'm passing a function pointer, to bind. Is this a warning I should just ignore, or is this a legitimate issue? Thanks for your help! Here's a sample app, followed by the warnings I'm seeing. #include <boost/lambda/bind.hpp> using boost::lambda::bind; using boost::lambda::_1; #include <vector> #include <map> #include <algorithm> int main() { enum choice { select, reject }; std::vector<long> questions; std::map<long, choice> answers; std::transform(questions.begin(), questions.end(), std::inserter(answers, answers.begin()), bind(std::make_pair<long, choice>, _1, select)); return 0; } c:\boost\boost\lambda\detail\lambda_traits.hpp(389) : warning C4180: qualifier applied to function type has no meaning; ignored c:\boost\boost\lambda\detail\lambda_traits.hpp(458) : see reference to class template instantiation 'boost::lambda::detail::bind_traits<T>' being compiled with [ T=std::pair<long,main::choice> (long,main::choice) ] c:\temp\lambda_warning_test\lambda_warning_test.cpp(20) : see reference to class template instantiation 'boost::lambda::detail::bind_tuple_mapper<T0,T1,T2,T3,T4,T5,T6,T7,T8,T9>' being compiled with [ T0=std::pair<long,main::choice> (long,main::choice), T1=boost::lambda::placeholder1_type, T2=const main::choice, T3=boost::tuples::null_type, T4=boost::tuples::null_type, T5=boost::tuples::null_type, T6=boost::tuples::null_type, T7=boost::tuples::null_type, T8=boost::tuples::null_type, T9=boost::tuples::null_type ] -------------------------------- John Wismar john.wismar@autozone.com
