  • 0

I would like to define the 32 (32 bit compilation) and 64 (64 bit compilation) in Visual C. Is there any predefined macros for this? I’ve scoured through MSDN in vain.

Do you think this kind of definition for 32 and 64 would work?

#define _32_ if !(defined __LP64__ || defined __LLP64__) || defined _WIN32 && !defined _WIN64
        // we are compiling for a 32-bit system
the else statement will be _64_ definition
        // we are compiling for a 64-bit system

Thanks!

    From the docs:

    _M_IX86: Defined for x86 processors. … This is not defined for x64 processors.

    _M_X64: Defined for x64 processors.

    _M_IA64: Defined for Itanium Processor Family 64-bit processors.

    _WIN32: Defined for applications for Win32 and Win64. Always defined.

    _WIN64: Defined for applications for Win64.

    Take your pick.
