undefined references when linking c++ program

Hi all,

I'm getting the following error messages when gcc links hello.cpp. Does anybody know what's wrong?

Thanks,

Andre

hello.cpp :

#include <iostream>

int main()

cout << "Hello world\n";
return 0;
}

Use the "g++" command when compiling/linking a C++ program, it will automatically link with the C++ runtime library.
