Question

我正在开发一个跨平台的c ++库。我的目标是WP8，我需要检测目标是WP8还是桌面Windows。

是否为WP8目标自动设置了标志？

我考虑过使用_WIN32，但无论如何它似乎都定义在两个平台上。

不确定这是否是您正在寻找的内容，但如果您正在使用Universal App / Portable库，则可以使用

进行检测

/*
 * When compiling C and C++ code using SDK header files, the development
 * environment can specify a target platform by #define-ing the
 * pre-processor symbol WINAPI_FAMILY to one of the following values.
 * Each FAMILY value denotes an application family for which a different
 * subset of the total set of header-file-defined APIs are available.
 * Setting the WINAPI_FAMILY value will effectively hide from the
 * editing and compilation environments the existence of APIs that
 * are not applicable to the family of applications targeting a
 * specific platform.
 */

#define WINAPI_FAMILY_PC_APP      2     /* Windows Store Applications */
#define WINAPI_FAMILY_PHONE_APP   3     /* Windows Phone Applications */
#define WINAPI_FAMILY_DESKTOP_APP 100   /* Windows Desktop Applications */


// example usage
#if WINAPI_FAMILY==WINAPI_FAMILY_PHONE_APP
// TODO:
#endif

C＃

#if WINDOWS_APP
// TODO
#endif

#if WINDOWS_PHONE_APP
// TODO
#endif
