[Boost-users] [phoenix] [range] I think I'm missing a couple things w/ these libs

I love the ideas behind these libs, but I think I need to figure out a bit more before I can use them. Here's an example that models what I'm trying to do for real as an experiment w/ using phoenix and range. I can't quite get it to build. I think I'm really close. I tried it w/ lambda before I found phoenix and I had to do some ret<> things to get past some errors, but I'm not sure what the equivalent in phoenix is, or if I should really need them. Also, I think there should be a way to instantiate a vector directly from a range w/o having to use begin() and end() somehow, but I can't find it. I've tried various approaches with <something> including transformed_range<> and any_range<> and haven't gotten them to work. The transformed line gives me errors complaining about missing result_type, iterator_category, value_type, difference_type, pointer, reference. I'm using GCC 4.2 on OS X Thanks! ---- #include #include #include #include <vector> class A {}; class B { public: A a; }; class C { public: static B BFromA(const A& a) { return B(); } }; std::vector<C> CsFromBs(std::vector<B> bs) { <something> cs = bs | boost::adaptors::transformed(boost::phoenix::bind(&C::BFromA, boost::phoenix::bind(&B::a, boost::phoenix::arg_names::arg1))); return std::vector<C>(boost::begin(cs), boost::end(cs)); }
