Why boost is trying to make a copy of A (a vector is a list of A*).
And how can I fix that without making A constructor public?
I have no idea why it'd be doing that -- some more code would be helpful. The following testcase seems to work fine: #include <iostream> #include <vector> #include <algorithm> #include <boost/bind.hpp> template <typename T> struct dereference_as { typedef T& result_type; template <typename P> result_type operator()(P ptr) { return *ptr; } }; void showfirst(char c) { std::cout << c << std::endl; } int main() { std::vector<char const*> v; v.push_back( "1" ); v.push_back( "2" ); v.push_back( "3" ); v.push_back( "4" ); v.push_back( "5" ); v.push_back( "6" ); std::for_each( v.begin(), v.end(), boost::bind( &showfirst, boost::bind( dereference_as<char const>(), _1 ) ) ); } ~ Scott
