Comment 1 Alex Szpakowski 2014-10-09 00:12:28 UTC 
SDL requires the Mac OS X 10.7 SDK (or newer) when compiling - although it supports down to OS 10.5 at runtime after it's compiled.

https://hg.libsdl.org/SDL/file/3331d2f57704/src/video/cocoa/SDL_cocoawindow.m#l25
Comment 2 Alex Szpakowski 2014-10-09 00:17:29 UTC 
It's also mentioned in the OS X readme: https://hg.libsdl.org/SDL/file/3331d2f57704/docs/README-macosx.md
Comment 3 Ryan C. Gordon 2015-02-19 02:57:25 UTC 
Yeah, Apple makes it really hard to keep old build environments working (although we strive to make older OS X releases work, even if you must build on a newer Xcode or OS X SDK).
