10.6.8 and ffmpeg

Dave,

I may not be seeing the entire picture (often happens!), but I don’t think there is actually a problem on 10.6. It uses the more recent SDKs mostly for the iPhone IOS stuff, I think, and maybe for a few other features.

It’s just written in that Availability.h Apple-sanctioned way that enables certain features on higher OS versions, but works on lower OS versions as well. 


For example, in MacOSX 10.7 there is a show and hide menu bar feature that is enabled if you are on 10.7, but worked around on 10.6.

#if (MAC_OS_X_VERSION_MIN_REQUIRED < 1070) && !defined(__LP64__)
    if (show) {
        ShowMenuBar();
    } else {
        HideMenuBar();
    }
#endif


one thing — in the code of libsdl 2.05 it has this:

#if MAC_OS_X_VERSION_MIN_REQUIRED < 1060
# error SDL for Mac OS X only supports deploying on 10.6 and above.


so I think 10.5 is out of luck. libSDL 2.02 or 2.03 was still OK on 10.5 I think. I couldn’t get 2.04 to work, and gave up trying as life is too short.
