unresolved overloaded function signal

["Paulo Flabiano Smorigo" <pfsmorigo gmail com>]

Hi everyone,

I have a signal in my code like this:

button.signal_clicked().connect(sigc::bind<int>( sigc::mem_fun(*this, &Red::setNumber), 1));

And two overloaded functions:

void Red::setNumber(int value);
void Red::setNumber(char* value);

When compile gives me an "unresolved overloaded function signal" error.

How can I fix this?

Thanks,
