then I get "void value not ignored as it ought to be" at the line: "FooFunc ff = put.getFooFunc();"

I get the same thing if I try: FooFunc ff = MHBase<Put>::fooFO(put);

Here's the code:

#include #include <iostream>

class MHBAccessor { template<class> friend class MHBase; template<class Derived> static int foo(Derived& derived, int i) { return derived.foo_(i); } }; typedef boost::function FooFunc;

template <class Derived> struct MHBase { Derived& derived() { return static_cast(*this); }

int foo(int i) { return MHBAccessor::foo(this->derived(), i); }

struct fooFO { fooFO(MHBase<Derived>& mhb) : mhb_(mhb) {} void operator()(int i) { mhb_.foo(i); }

This returns void. FooFunc expects int. try

int operator()(int i) { return(mhb_.foo(i)); }
