mbue is correct, that's the reason you're getting the error... to elaborate a bit more, C used to support not explicitly defining a return type, C++ doesn't support this.

Valid in C, not valid in C++:

MyFunc(){}

Solution 3

You can declare a function or prototype as:

MyFunc()
{
}

The compiler assumes the return value as int. But the comiler tells you that default return values are not supported!

int MyFunc()
{
  return 0;
}

or

void MyFunc()
{
}

is the right one.

Of course this is the basis !!!

void, no return, C++ should declare by default int, so you don't know so error ?

The best : when no return void.

If return declare clearly the type.

The two last statments are purely C and not C++ : let's play with them.

what?

This is correct, they changed the standard so you must specific the return type from a function.

Solution 1

Without more info, I am guessing a bit, but I think you will find you need a forward reference to the class object before you can use it.

If this doesn't help, then we would need to see the relevant code fragment around the line the compiler is complaining about.

Solution 2

It looks like you edited the error message and removed the line number. Show us the complete error message and a few surrounding lines so we can help you.
