VS2015 compiler error C3861: 'LCMapStringEx': identifier not found

Question

_{Tuesday, January 10, 2017 1:41 PM}

My C++ code compiles fine with VS 2013 but when I have compiled with VS 2015 I get this error:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\atlmfc\include\atlwinverapi.h(710): error C3861: 'LCMapStringEx': identifier not found

I don't use LCMapString anywhere in my code, so I don't know where this come from? Can you help me in resolving this error?

Welcome to the MSDN forum.

Refer to your description, your issue is more relates to the development of C++.

Hi smhaneef,

thanks for posting here.

>>I don't use LCMapString anywhere in my code, so I don't know where this come from? Can you help me in resolving this error?

Have you tried to manually delete all the obj files， then clean and rebuild your project with vs 2015?  Or you could create a new projct with vs 2015, add your source files into this new project and rebuild again.

Hope this could be help of you.

Best Regards,

Sera Yu

Does your code have a #include statement for either Windows.h or Winnls.h?  If not, insert one.

Yes. My code have a #include statement for both Windows.h or Winnls.h.

i am getting this compiler error while building the StdAfx.cpp file.

1> Build started: Project: CwControls, Configuration: Debug Win32
1>cl : Command line warning D9035: option 'Zc:forScope-' has been deprecated and will be removed in a future release
1>  StdAfx.cpp

I tried it by deleting all the obj files manually. Still I have the same problem. I need to try creating a new project with vs 2015 and adding the source files.

Correcting the version details of _WIN32_WINNT, _WIN32_WINNT solved the issue.

The atlwinverapi.h header references LCMapStringEx when it thinks the project is targeting Vista and later Windows versions.  Check to make sure that nothing in your project is conflicting to cause Windows.h and/or Winnls.h headers to exclude the LCMapStringEx function prototype.  You can specify that you are targeting Vista and later versions by using -

#define NTDDI_VERSION NTDDI_VISTA
#define _WIN32_WINNT _WIN32_WINNT_VISTA

before including the windows and atl headers.  See Using the Windows Headers

Please use these macros in the Project .cpp files.

#define _WIN32_WINNT 0x0A00

#define _USING_V110_SDK71_
#define _ATL_XP_TARGETING

Notice that the value of _WIN32_WINNT depends of your computer.

Please research at your code deeply.

Thanks

Correcting the version details of _WIN32_WINNT, WINVER solved the issue.
Go to:
Properties->Configuration properties->C/C++->Preprocessor->Preprocessor Definitions and check what macros are defined.
changing them to 
                   NTDDI_VERSION= 0x06030000
                   WINVER=0x0A00
                   _WIN32_WINNT=0x0A00
solved my problem.
