Hello, I really like the BLL and would like to use it as much as possible. I have run into a small problem though. My code looks like this: #include <boost/lambda/bind.hpp> #include <boost/lambda/lambda.hpp> #include <map> #include <vector> class A { public: A(int a, int b) : a_(a), b_(b) { } int a_; int b_; }; int main() { using namespace boost::lambda; std::vector<A> v; v.push_back(A(1, 2)); typedef std::map<int, int> Map; Map m; for_each(v.begin(), v.end(), bind(&Map::insert, std::make_pair(bind(&A::a_, _1), bind(&A::b_, _1)))); return 0; } What I want to do is to populate a map with the information from the vetctor v. For each element in v I want to insert a value and a key into the map something like this: void operator()(const A& a) const { m_.insert(std::make_pair(a.a_, a.b_)); } I found some information on how to use member variables as targets in the BLL documentation and that is what I have tried to use in the code above. It won't compile however, using g++ I get the following error: g++ -c -o test.o test.cpp test.cpp: In function `int main()': test.cpp:27: error: no matching function for call to `bind(<unknown type>, std::pair<boost::lambda::lambda_functor<boost::lambda::lambda_functor_base<boost::lambda::action<2, boost::lambda::function_action<2, boost::lambda::detail::unspecified> >, boost::tuples::tuple<int A::*, const 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::lambda::lambda_functor<boost::lambda::lambda_functor_base<boost::lambda::action<2, boost::lambda::function_action<2, boost::lambda::detail::unspecified> >, boost::tuples::tuple<int A::*, const 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> > > >)' scons: *** [test.o] Error 1 scons: building terminated because of errors. If someone here has any ideas of how to accomplish this it would be really nice! Thanks in advance! Regards, Mattias
