是否有任何宏来确定我的代码是否正在编译到 Windows? [英] Are there any macros to determine if my code is being compiled to Windows?

问题描述

我想检测我正在编译的操作系统是否是 Windows.有没有我可以检查的简单宏来验证这一点?

I would like to detect whether the OS I'm compiling on is Windows. Is there a simple macro I can check to verify that?

推荐答案

一些编译器提供宏来指示 Windows 构建环境.但这些会因编译器而异，甚至在 Windows 上的相同编译器上，如果目标环境是 不是 专门的 windows.通常是 __WIN32__，但并非总是如此.

Some compilers offer macros to indicate a Windows build environment. But these will vary from compiler to compiler, and even on the same compiler on Windows if the target environment is not exclusively windows. Usually it's __WIN32__, but not always.

#if defined (__WIN32__)
  // Windows stuff
#endif

有时它可以是 _WIN32、__CYGWIN32__，或者可能只是编译器指示符 (_MSC_VER).

Sometimes it can be _WIN32, __CYGWIN32__, or possibly just the compiler indicator (_MSC_VER).

如果您知道要构建的环境(来自 makefile)，那么您通常可以在命令行中传入 #define，例如g++ -D __WIN32__ yourfile.c".

If you know the environment you'll be building in (from the makefile) then you can usually pass in the #define on the command line, like "g++ -D __WIN32__ yourfile.c".
