Re: [boost] [parameter] type requirement compiler error

The following example raises the same Boost.Parameter error
and it uses no graph library:
// File: 01.cpp
#include <boost/parameter.hpp>
#include <iostream>

BOOST_PARAMETER_NAME(x)
BOOST_PARAMETER_NAME(y)

BOOST_PARAMETER_FUNCTION(
    (void),
    f,
    tag,
    (required
        (x, *)
        (y, (tag::x::_))
    )
) {
    std::cout << x << " " << y << std::endl;
}

int main ( void )
{
    f(1, 2);
    return 0;
}

Reply:
IME you can't use (void) as a return type.  As a workaround I use (bool) and return a constant (true or false).
