安装 Visual Studio 2010 后出现错误 C1189

Question

I installed VS2010 after a drive crash, prior I had VS2005 and everything was fine.

Now on compiling a C++ app that was fine previously I am seeing a couple of errors which I just cannot figure out.

Error 1 error C1189: #error: This file requires _WIN32_WINNT to be #defined at least to 0x0403. Value 0x0501 or higher is recommended. C:\Program Files\Microsoft Visual Studio 10.0\VC\atlmfc\include\atlcore.h 35 1 BIOXGINA

#ifndef __ATLCORE_H__
#define __ATLCORE_H__

#pragma once

#ifdef _ATL_ALL_WARNINGS
#pragma warning( push )
#endif

#pragma warning(disable: 4786) // identifier was truncated in the debug information
#pragma warning(disable: 4127) // constant expression

#include <atldef.h>
#include <windows.h>
#include <ole2.h>

#include <limits.h>
#include <tchar.h>
#include <mbstring.h>

#include <atlchecked.h>
#include <atlsimpcoll.h>

34.  #if _WIN32_WINNT < 0x0403
35.  #error This file requires _WIN32_WINNT to be #defined at least to 0x0403. Value 0x0501 or higher is recommended.
36.  #endif

#pragma pack(push,_ATL_PACKING)
namespace ATL
{
/////////////////////////////////////////////////////////////////////////////
// Verify that a null-terminated string points to valid memory
inline BOOL AtlIsValidString(
_In_z_count_(nMaxLength) LPCWSTR psz,
_In_ size_t nMaxLength = INT_MAX)
{
(nMaxLength);
return (psz != NULL);
}

If I comment out the above lines, I then get

error C3861 Identifier not found on line 111 below.

I presume I'm only getting this because I commented the above lines?

HRESULT Init() throw()
{
    HRESULT hRes = S_OK;

111.        if (!InitializeCriticalSectionAndSpinCount(&m_sec, 0))
    {
        hRes = HRESULT_FROM_WIN32(GetLastError());
    }

    return hRes;
}

I would appreciate any assistance on this. Don't really want to reinstall 2005.

Answer 1

This Microsoft Connect issue has this potential solution:

edit file "stdafx.h" and change the value defined for _WIN32_WINNT and WINVER to 0x0502.

More discussion here about this error on the MSDN C++ forum: Problem with older VC Solution .

Answer 2

Your project targets a Windows version that is no longer supported by the newer compiler (or anything else).

You have to select a minimum target version that is Windows XP ("Windows 5") or later.

Answer 3

Project Property –> Configuration Properties –> C/C++ -> Command Line ->Additional Options ：add this code

/D “_WIN32_WINNT=0×0501”

if in Windows server 2003，0×0501chagnes to 0×0502； if in Windows 7， 0×0501chagnes to 0×0601

works well

Answer 4

Thank you both for the replies.

I managed to get rid of the error message as follows. The Context.h looked liked this.

  #pragma once

  #define _WIN32_WINNT 0x0400

  #include <windows.h>
  #include <winwlx.h>
  #include <ObjBase.h>
  #include <comdef.h>
  #include <atlbase.h>

  extern CComModule _Module;

  #include <atlcom.h>
  #include <vector>

I moved the #define _WIN32_WINNT 0x0400 to then end after all the includes, and it compiled Ok. Odd, but it worked.

I will however alter it to 0x0502 as suggested.

thanks
