VC++2005 newbie question

That one is declared in WinNT.h as

typedef
VOID
(NTAPI *PFLS_CALLBACK_FUNCTION) (
    IN PVOID lpFlsData
    );

I did a search on "PFLS" and it's not in my project.  If this is called directly, it's from Microsoft's code and not in anything I should be changing.

What follows is the Output Window section of my BuildLog.htm
Compiling...
stdafx.cpp

There is something really going wrong with your installation. What is the size of your WinNT.h?

>>>> That one is declared in WinNT.h as

actually the errors are in WinBase.h and *not* in WinNt.h . Winbase.h most likely was included via #include <windows.h>-

>>>> Compiling... stdafx.cpp
The stdafx.cpp is the source to create the 'precompiled header file'. It should have only one single statement:

#include "stdafx.h"

and nothing else. In the C++ - Precompiled Header  properties it should have the option 'Create PCH via stdafx.h' switched on and it should be the only cpp where it was switched on.

>>>> error C2065: 'PFLS_CALLBACK_FUNCTION' :

C2065 means that the compiler didn't recognize that 'PFLS_CALLBACK_FUNCTION' was typedef'd as a new type of a function pointer, means the 'PFLS_CALLBACK_FUNCTION' could be any arbitrary name here.  It expects a *already defined* type instead of 'PFLS_CALLBACK_FUNCTION' here what means that parts before that name were not properly recognized. Here we have VOID and NTAPI  (if you have the same definition as jkr and me). But both were used a hundred of times in definitions above, so actually it could not fail here if tthese macros were unknown (the definitions were in winnt.h and windef.h) but you would have get a cillion errors before.

errors like that occur for various reasons:

1. you have mixed-up include folders. e. g. from VC6 and VC8 which both are in the project include folders or in the common include folders.

2. You included a header *above* windows.h but that header wasn't properly nested, e. g. there is a missing #endif or a class declaration wasn't closed with ;

3. You included <windows.h> above "stdafx.h" , so it was ignored by the compiler but not by the precompiler. Or you included <windows.h> below "stdafx.h" though it already was included in stdafx.h. Then the compiler errors come because macro protection like

#ifndef _WINBASE_
#define _WINBASE_

at the very top of winbase.h that should prevent from including winbase.h twice would not work cause macros were not evaluated when dealing with precompiled headers.

What to do?

- Check the PCH settings of stdafx.cpp
- Check that it included "stdafx.h" only and nothing else.
- Check stdafx.h whether it was updated to include more headers.
- If yes, put these includes below the old ones and not above.
- Check that each header compiles and is correctly nested.
- For bigger headers you can do that by renaming the header to a .cpp
  or a .c  (for pure C headers) and compiling it. (not using PCH).
- Doing so, you additionally will find out whether the header includes
  all depending headers and have appropriate forward declarations.

if stdafx.cpp still doesn't compile, you could add a new source to your project which contains nothing but a

#include <windows.h>

and where you switched off PCH. If that doesn't compile with the same errors your installation was corrupt. If it compiles there is something wrong with your stdafx.h.

The PCH settings of stdafx.cpp look fine.  I tried to repair my install from the disk, but it didn't help.  What follows is my stdafx.h file.  If it was updated to include more headers, I can't see where.

Thanks again for your help.

>>>> to move my SDK folder to the top of my include folders
that isn't a solution but a workaround. If that worked it means that other include folders contain the same header files than the SDK folders. Visual Studio may have taken them from 'include' environment variable at installation time. You should spot these folders in both the list of the include folders and the list of library folders (where most likely a similar problem exists). I assume you used another C/C++ compiler before VC where the environment variables 'include' and 'lib' were set.

>>>> PAQ with refund
No problem with that.

Regards, Alex

Alex,

Thanks for understanding.  Obviously, I'll be using your help in the (very near) future, so you won't lose any business.

In case you were wondering, I got my answer from MSDN forum "Visual C++->General"
