I have no idea what this means. But here is the code that it supposely is happening in.

Some where an include file that has no include guard is including itself (directly or indirectly).

Use /showIncludes ("Configuration Properties/C/C++/Advanced/Show Includes" in the IDE's project options) to get help with this.

The easiest way to fix your problem is at the top of all of your header files add:

#pragma once

Do this always everytime you make a header file in C++. If your compiler doesn't support the above (I seriously doubt anyone uses a compiler that doesn't support it, Visual Studio which you use does) then you can use include guards.

The #pragma once directive ensures that your includes will only be included once.

You will get the error you got if you have the following situation:

file: a.h

#include "b.h"

file: b.h

#include "a.h"

Then in your main app you include one of the 2 header files.

You can fix your situation by doing the following:

file: a.h

#pragma once
#include "b.h"

file: b.h

#pragma once
#include "a.h"

std::stringstream is in the sstream header, so:

#include <sstream>

I think that your solution was recursive inclusion as Michael Burr stated, but for the record it can also happen with only correct inclusions, when the hierarchy is too deep.

For instance, if you have 1024 files, each one including only the next one.

I just encountered this issue when I accidentally had:

header/foo.hpp
source/foo.hpp

Rather than:

header/foo.hpp
source/foo.cpp

Thus causing:

#include "foo.hpp"

To cause this error. Thought I'd add this answer as I was feeling stumped: no deep include chain, no forgotten header guard, I wasn't doing #include "foo.cpp"... except I was and didn't realise it.
