Hi,

The above compiles, but...does nothing. How can I enforce calling of operator () ?
typedef boost::function<void(void)> functor; std::vector<functor> functors; ... using namespace boost::lambda; std::for_each( functors.begin(), functors.end(), bind(&functor::operator(),_1)); bind here is boost::lambda::bind, in #include <boost/lambda/bind.hpp>, not to be confused with boost::bind. On the other hand, you can rewrite the stuff using Boost.Bind instead of Boost.Lambda: std::for_each( functors.begin(), functors.end(), boost::bind(&functor::operator(),::_1)); We are using here a different "bind" and a different "_1". This name clash between both Boost libraries is a constant source of grief. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
