VS 2015 compiler error 'LCMapStringEx': identifier not found

Question

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

C:\VS\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?

Answer 1

I had the same problem. For me the cause was this: Part of the project had _WIN32_WINNT set in such a way that XP was supported, other files didn't have this define. So the MFC headers were included with different values for the supported platform leading to this strange error.

Answer 2

The definition is guarded for the minimum target windows version. This guard uses one of your definitions or NTDDI_VERSION (which is created from the other definition within (sdkddkver.h).

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. Here 0A00 is for windows10.Refer below link https://msdn.microsoft.com/en-us/library/windows/desktop/aa383745(v=vs.85).aspx

Answer 3

I Solved the problem. I had to manually delete all the obj files generated by the previous compiler, as the clean and rebuild option in VS 2015 seems that did not remove them correctly.

Answer 4

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

(WINVER or _WIN32_WINNT)

Answer 5

I faced similar issue when I migrated project from Visual Studio 2005 to Visual Studio 2015.

Open the Vcxproj in notepad or any of your favorite editors and then search for <PreprocessorDefinitions> tag in my case I removed the WINVER=0x0501, when I removed it started working.

Answer 6

In StdAfx.h define the following macros:

//For Windows 10

NTDDI_VERSION 0x0A000000

#define WINVER 0x0A00

#define _WIN32_IE 0x0A00

Also refer below MSDN links for WINVER & NTDDI_VERSION according to your environment.
