But references are just lost and this is not good.

So, here is my question: How can I make this working ?

The arguments of call_something are passed by value. Try: template<class ...classes> boost::function0<void> call_something(classes&... c) In Christ, Steven Watanabe Thank you, It actually allows me to use references in these functions. I just tried and g++ is waiting for only references but I need to use pointers and/or values too. There is a way to use mixed types in template variadic functions ? Regards, Yannick POTIN
