Hello! I wrote two simple examples to demonstrate the problem. First one is: //////////////////////////////////////////////////////////////// #include <vector> #include <utility> #include <algorithm> #include <cassert> #include <boost/lambda/lambda.hpp> #include <boost/lambda/bind.hpp> int main() { std::vector<int> v1; v1.push_back(1); v1.push_back(2); v1.push_back(3); std::vector<std::pair<int*, bool> > v2; namespace bll = boost::lambda; std::transform(v1.begin(), v1.end(), std::back_inserter(v2), bll::bind(std::make_pair<int*, bool>, &bll::_1, true)); assert(v2.size() == 3); return 0; } //////////////////////////////////////////////////////////////// This program compiles and works fine. The second program is: //////////////////////////////////////////////////////////////// #include <vector> #include <utility> #include <algorithm> #include <cassert> #include <boost/tuple/tuple.hpp> #include <boost/lambda/lambda.hpp> #include <boost/lambda/bind.hpp> int main() { std::vector<int> v1; v1.push_back(1); v1.push_back(2); v1.push_back(3); namespace bll = boost::lambda; std::vector<boost::tuple<int*, bool> > v3; std::transform(v1.begin(), v1.end(), std::back_inserter(v3), bll::bind(boost::make_tuple<int*, bool>, &bll::_1, true)); assert(v3.size() == 3); return 0; } //////////////////////////////////////////////////////////////// It doesn't compile: $ g++-4.3.2 -I /usr/local/dev/boost-1.38.0/include/ main2.cpp main2.cpp: In function 'int main()': main2.cpp:22: error: no matching function for call to 'bind(<unresolved overloaded function type>, const boost::lambda::lambda_functor<boost::lambda::lambda_functor_base<boost::lambda::other_action<boost::lambda::addressof_action>, boost::tuples::tuple<boost::lambda::lambda_functor<boost::lambda::placeholder<1>
, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type> > >, bool)' $
What's wrong in the second program? Thank you beforehand! -- Sincerely yours, Dmitry V. Krivenok Orange System Co., Ltd.
