Is _WIN32 defined for x64?
The symbol _WIN32 is defined by the compiler to indicate that this is a (32bit) Windows compilation. Unfortunately, for historical reasons, it is also defined for 64-bit compilation.
What is_ WIN32 in C?
WIN32 is a user-defined flag which may be required by some headers. _WIN32 is automatically defined by the visual C/C++ compiler. Since it begins with an _ followed by a capital character, it is reserved by the implementation (meaning the C/C++ toolchain provider).
Where is _WIN64 defined?
_WIN64 Defined as 1 when the compilation target is 64-bit ARM or x64. Otherwise, undefined. _WINRT_DLL Defined as 1 when compiled as C++ and both /ZW (Windows Runtime Compilation) and /LD or /LDd compiler options are set. Otherwise, undefined.
What is a 64-bit compiler?
After you convert your 32-bit driver source code to use the new data types, you can use the 64-bit compiler to identify any type-related problems that you initially missed. The first time you compile this code for 64-bit Windows, the compiler might generate many pointer-truncation or type-mismatch warnings.
How do I compile 64-bit gcc?
Just type the following command on Linux terminal.
