<snip> ---------------------------------------------- After compilation, I get this output (watch the memory addresses): 0xbfc8f994::operator()(): 1 0xbfc8f990::operator()(): 2 0xbfc8f984::operator()(): 1 0xbfc8f984::operator()(): 2 I really don't know what happened (even if I can imagine). 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 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
