You shouldn't have to use the SigC namespace, from what I understand it
that is for backwards compatibility with sigc++ 1.2

I think slot.h is also for the backwards compatibility. In your example
you should be using sigc::ptr_fun() rather than SigC::slot.

not sure, doesn't happen here, attaching revised example.
Tim.
#include <iostream>
#include <sigc++/sigc++.h>
#include <sigc++/slot.h>
using namespace std;
void hello() { cout << "hello, " << flush; }
void world() { cout << "world!" << endl; }
int main()
{
// I wouldn't use signal as a variable name.
sigc::signal<void> signal;
signal.connect(sigc::ptr_fun(&hello));
signal.connect(sigc::ptr_fun(&world));
signal.emit(); // or just signal()
cout << "Good night, Moon." << endl;
}
