mstorsjo created this revision. _strftime_l is only available in the numbered msvcrt versions (starting from msvcr80.dll). In the default configuration, mingw targets the unversioned msvcrt.dll - and there, _strftime_l is not available (not even on windows 10).
If __MSVCRT_VERSION__ is set to a higher value (indicating a non-default target and wanting to link to msvcrXX.dll), use the correct function. https://reviews.llvm.org/D37468 Files: include/support/win32/locale_win32.h Index: include/support/win32/locale_win32.h =================================================================== --- include/support/win32/locale_win32.h +++ include/support/win32/locale_win32.h @@ -100,7 +100,11 @@ #define iswxdigit_l _iswxdigit_l #define towupper_l _towupper_l #define towlower_l _towlower_l +#if defined(__MINGW32__) && __MSVCRT_VERSION__ < 0x0800 +#define strftime_l( __s, __l, __f, __tm, __loc ) strftime( __s, __l, __f, __tm ) +#else #define strftime_l _strftime_l +#endif #define sscanf_l( __s, __l, __f, ...) _sscanf_l( __s, __f, __l, __VA_ARGS__ ) #define vsscanf_l( __s, __l, __f, ...) _sscanf_l( __s, __f, __l, __VA_ARGS__ ) #define sprintf_l( __s, __l, __f, ... ) _sprintf_l( __s, __f, __l, __VA_ARGS__ )
