boost::function compile problems

I am having some problems with boost::function, from the documentation
I suppose this should work:

#include <iostream>

// I have moved some include files slightly
#include "function.hpp"

void foo()
{
        std::cout << "Hello!" << std::endl;
}

int main()
{
        boost::function<void> f;
        f = &foo;
        f();
}

However with gcc 2.96 I get these errors:

 g++ -W -Wall -O2 -o test testfunction.C
In file included from testfunction.C:15:
