It's 2016 not 2011. The Standard (i.e. C++14) specifies the *types* of main function that all implementations support. int main() and int main(void) are the same type. In any case, additional implementation-defined forms have always been allowed, and G++ allows int main(void), so telling the OP it isn't correct isn't very helpful. That's not the cause of his error.
