C代码宏的OS X版本（狮子与否）的检测？ [英] C macro for OS X version (Lion or not) detection?

问题描述

有pdefined C代码宏一$ P $检测OS X的版本？我知道 __ __ APPLE 和 __ __ MACH 存在，但这些都是二进制的。是否有 __ __ APPLE_CC ，表示狮子特定值？

Is there a predefined C macro for detecting the version of OS X? I know __APPLE__ and __MACH__ exist, but those are binary. Is there a specific value for __APPLE_CC__ that indicates Lion?

在特定的，狮子添加的定义函数getline（）到＆LT; stdio.h中＆GT; 在狮子和这将是很好能够检测code是否被编译在Lion上还是不解决编译错误。

In particular, Lion added a definition of getline() to <stdio.h> in Lion and it would be nice to be able to detect whether or not code was compiling on Lion or not to work around compilation errors.

具体来说，我指的是在猛砸建设的Unix C code（外X $ C $的c）。

Specifically, I'm referring to building Unix C code in Bash (outside of XCode).

推荐答案

的 Availability.h 宏允许您检查之前编制和运行时版本依赖性。见讨论<一个href=\"http://developer.apple.com/library/mac/#documentation/DeveloperTools/Conceptual/cross_development/Using/using.html\"相对=nofollow>这里。

The Availability.h macros allow you to check for compile- and run-time version dependencies. See the discussion here.
