Subject: [Boost-users] Trouble with template on boost::function and boost::bind
From: pwx (airyai_at_[hidden])

I tried to create a template function that receives boost::function as
parameter. Say like this:
template <typename T1, typename T2>
void proc(const boost::function<void(const T1&, T2&)> &p) {
// ...
}
void f(const string& s1, string&s2) {
// ...
}
Everything goes ok when I called proc( boost::function<void(const
string&, string&)>(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::_bi::unspecified, F,
boost::_bi::list2<boost::arg<1>, boost::arg<2> > >)’
Anyway to fulfill this design purpose? Thanks.
