C macro for OS X version (Lion or not) detection?

Question

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 val

Answer 1

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

Answer 2

Check in /usr/include/AvailabilityMacros.h - it contains macros such as:

#if MAC_OS_X_VERSION_MIN_REQUIRED >= MAC_OS_X_VERSION_10_7
    #define DEPRECATED_IN_MAC_OS_X_VERSION_10_7_AND_LATER    DEPRECATED_ATTRIBUTE
#else
    #define DEPRECATED_IN_MAC_OS_X_VERSION_10_7_AND_LATER
#endif

I came across this stuff because 'openssl/sha1.h' has been slathered with 'deprecated' attributes for Lion, so compiling git gets warnings galore.
