OK, does anyone know a proper solution for this?
Without commenting out this line, here is the error that I get:
[...]
Exception.cxx
C:\Program Files\Microsoft Visual Studio 9.0\VC\include\stdio.h(358) :
error C3163: '_vsnprintf': attributes inconsistent with previous declaration
C:\Program Files\Microsoft Visual Studio
9.0\VC\include\stdio.h(350) : see declaration of '_vsnprintf'
The relevant lines from stdio.h are (350 to 358):
_Check_return_opt_ _CRT_INSECURE_DEPRECATE(vsnprintf_s) _CRTIMP int
__cdecl vsnprintf(_Out_cap_(_MaxCount) char * _DstBuf, _In_ size_t
_MaxCount, _In_z_ _Printf_format_string_ const char * _Format, va_list
_ArgList);
#if __STDC_WANT_SECURE_LIB__
_Check_return_opt_ _CRTIMP int __cdecl vsnprintf_s(_Out_z_cap_(_DstSize)
char * _DstBuf, _In_ size_t _DstSize, _In_ size_t _MaxCount, _In_z_
_Printf_format_string_ const char * _Format, va_list _ArgList);
#endif
_Check_return_opt_ _CRTIMP_ALTERNATIVE int __cdecl
_vsnprintf_s(_Out_z_cap_(_SizeInBytes) char * _DstBuf, _In_ size_t
_SizeInBytes, _In_ size_t _MaxCount, _In_z_ _Printf_format_string_ const
char * _Format, va_list _ArgList);
__DEFINE_CPP_OVERLOAD_SECURE_FUNC_0_3(int, _vsnprintf_s, char, _Dest,
_In_ size_t, _MaxCount, _In_z_ _Printf_format_string_ const char *,
_Format, va_list, _Args)
#pragma warning(push)
#pragma warning(disable:4793)
__DEFINE_CPP_OVERLOAD_STANDARD_NFUNC_0_2_ARGLIST_EX(int,
__RETURN_POLICY_SAME, _CRTIMP, _snprintf, _vsnprintf, _Pre_notnull_
_Post_maybez_ char, _Out_cap_(_Count) _Post_maybez_, char, _Dest, _In_
size_t, _Count, _In_z_ _Printf_format_string_ const char *, _Format)
Why _vsnprintf seems to be conflicting from within Microsoft's own
stdio.h is beyond me (AFAIK this is the stdio.h that comes with VC++).
Thanks
