Setting of the project in "C / C -> Language -> Treat Wchar_t as Built-in Type" to "no" (ORIGINALLY IT WAS: "YES (/ zc: wchar_t)".
/ Zc: wchar_t (WCHAR_T is this type of machine)
See
/ Zc (consistency)
/ Zc: wchar_t
If / zc: WCHAR_T is not specified, the compiler requires you or defines a file (such as Wchar.h) in a wide-header file that defines Wchar_t. Wchar_t is usually defined as unsigned short.
When specifying / zc: wchar_t compiler option, type WCHAR_T is a native type mapped to __wchar_t, and its mapping mode is the same as Short map to __INT16.
If you use / zc: wchar_t, the compiler identifies WCHAR_T as a native type. For more information on Wchar_t, see
Data type range
.
__wchar_t is always available.
By providing overloading for WCHAR_T's unsigned short format and __wchar_t variants, you can create libraries that easily use (or unused) / zc: wchar_t compilation, and no need to provide the library two different Version (enabled and version of the ZC: Wchar_t).
Specify / zc: wchar_t, define _wchar_t_defined and _native_wchar_t_defined symbol; for more information, see
Predefined macro
