winnt.h(222): Error C2146 ...

• renemt

  Hi Hans-Jochen,
  
  seems to me that ctlutil.h is missing an include so that LONG is not defined at that point.
  Make sure to include winnt.h or windows.h before using LONG in ctlutil.h.
  
  HTH,

  I may have a solution that doesn't involve modifying the base files. In "Tools -> Options -> Projects and Solutions -> VC++ Directories -> Include Files" make sure the default include folders are first, and put any extra include folders you want here.

  In the project properties under "C/C++ -> General" make sure the "Additional Include Directories" is empty. Any additional include directories should be in the folder above.

  This solved all my problems. Hope it solves yours!

  Okay, okay, I goofed - on three counts.
  
  >>I am trying to throw VC++ 2005 Express on Windows 2000 Pro SP4 at a modifed version of the amcap sample program of DirectShow.  This is the version I have downloaded with DirectX 9.0b on 11 Oct. 2004 ...<<
  
  The Platform SDK contains DirectShow and I have kept it during installation, so I suppose that is what I am using.
  
  >>I have the platform SDK downloaded, and putting its include directory before or after the baseclasses and DXSDK include directories does not change anything.<<
  
  Wrong.  Putting the Platform SDK include directory first gets rid of the C2146 error.  Interesting is that the mouse-over display says "typedef void *POINTER_64" when I am over POINTER_64 and "typedef void *PVOID64" when I am over PVOID64 ...
  
  The third goof is missing the Platform SDK's subdirectory "Include\atl".  (VC++ 6 either has the corresponding ATL\Include directory apparently automatically used.)
  
  That leaves me with just one error to figure out,
  
     line 278 "operator=(LONG);" in baseclasses\ctlutil.h missing a type specifier (error C4430)
  
  I have made sure that the baseclasses of the directShow piece in the Platform SDK is used.
  
  I apoogize for the premature alarms.
  
  Cheers,             Jochen

  Jonathan,
  
  thanks for your advice.  Yes, it makes the compilation error C4430 in ctlutil.h go away.  This is 100% Microsoft's code, not mine, so I will post a bug report.  Your heroic efforts at implementing faithfully the C++ standard have struck here - VC++ 6 SP5 does not complain about this code (taken from DXSDK 9.0b where this passage is identical).
  
  Cheers,             Jochen

  Thanks a lot everyone. This discussion helped me alot to get started with VS2005 and directshow.
  
  Thanks,

  I have an orrorific solution for problem C2146.
  
  I found into file baseTsd.h the definition for POINTER_64 which is this,
  
  at line 22 more less:
  
  
  

  #ifndef _BASETSD_H_

  #define _BASETSD_H_

  #if !defined(_MAC) && (defined(_M_MRX000) || defined(_M_AMD64) || defined(_M_IA64)) && (_MSC_VER >= 1100) && !(defined(MIDL_PASS) || defined(RC_INVOKED))

  #define POINTER_64 __ptr64  // <-- This code is not called for some reason.

  typedef unsigned __int64

  
  
  I simply put this definition over the POINTER_64 typedef like this:
  
  

  #define POINTER_64 __ptr64  // <<---- ORROR !!!

  typedef void *PVOID;

  typedef void * POINTER_64 PVOID64;
  
  And I was able to compile my Torque Game Engine SDK with absolutelly no functionality problems.

  I have a similar error

  ...which are all in winnt.h, which is included from windows.h (as far as I can tell - is there a problem with the "show Includes" option). Is there an updated set of h files I need to download

  I am experiencing this issue as well...is there an "official" solution
  
  

• Brent Williams

  I had a similar error. One which I just fixed, but thought I should post the solution.  In case someone else runs accross this same issue, I could potentially save you some work.
  
  Basically what happened was that I thought that the issue was with the Visual Studio Include files order (see Tools->Options->Projects and Solutions->VC++ Directories->Show directories for: Include files). Only a while later did I realize that the problem was that the project itself had some include files (see project Properties->Configuration Properties->C/C++->General) that takes precedence over the Visual Studio Include files.  I also included the directshow header files in the VS Include files, but this time, since they were explicitly listed there, I could choose which order I wanted them in, i.e. that the Platform SDK had higher priority than the DirectX directories.
  
  Other than that I had to patch a few bugs with the BaseClasses source files. One was the "operator=(LONG);" issue already discussed elsewhere in this thread.  In a few places there were "int"s declared in for loops that had to be declared outside the for loops.

  This does indeed look like the same issue. I would first use the /showIncludes compiler option to ensure that you have a consistent set of include files. If that doesn't show up any problems then I would ensure that the version of the Platform SDK that you are using matches the version of Visual C++ 2005 that you have installed.

  There are several bugs in the BaseClasses when you compile it with vs2005, but they are easy to fix. There are two for scoping errors, the static variable definition error and that one for the operator= which was pointed out. Thats what I can remember.
  But one thing for you to try. When I was compiling an application the other day, it was complaining that something was undefined, but it should have been. I managed to trace this back to _WIN32_WINNT not being defined. So double check that you do have this defined. Also, make sure that any other preprocessor directives that you need are also defined.

  Hi,
      I fixed the problems mentioned above. The only problem now is the compiler can't find <fstream.h>. I tried just including <fstream> but it didn't recognise the functions (this also happens in VC++ 6.0).
       Any ideas would be helpful.
  
  All the best.
  
  

• bitbonk

  No: the problem here is that this member operator function does not have a return type:
  
      operator=(LONG);
  
  By looking at the code it seems that it should be:
  
      COARefTime& operator=(LONG);
  
  
  

• Whololo

  ah, fixed the problem.. if i include <fstream> I have to declare std namespace before using the code. Thanks for the help with the original compiling problems.
  
  Cya!
