[Boost-users] Trouble with template on boost::function and boost::bind

I tried to create a template function that receives boost::function as parameter. Say like this: template void proc(const boost::function &p) { // ... } void f(const string& s1, string&s2) { // ... } Everything goes ok when I called proc( boost::function(f) ). But when I try this: proc(boost::bind(f, _1, _2)); The compiler refused with the error: no matching function for call to ‘proc(boost::_bi::bind_t, boost::arg<2> > >)’ Anyway to fulfill this design purpose? Thanks.
