From: Laurence Passmore Date: Mon, 26 Mar 2007 23:22:45 +0100 To: "A list for developers using the SDL library. \(includes SDL-announce\)" <sdl@lists.libsdl.org> Subject: [SDL] SDL_config_macosx.h: MAC_OS_X_VERSION_MIN_REQUIRED Hi, I just compiled my SDL application on Mac OS X with -Wundef and it threw a number of errors. Of note was: SDL_config_macosx.h: 34 warning: "MAC_OS_X_VERSION_MIN_REQUIRED" is not defined Line 34 is: #if ( (MAC_OS_X_VERSION_MIN_REQUIRED >= 1030) || (!defined (__POWERPC__)) ) Now according to this mailing on the Apple developer lists: http://lists.apple.com/archives/Xcode-users/2005/May/msg00602.html that particular #define was removed from the gcc compiler defaults and AvailabilityMacros.h (/usr/include/AvailabilityMacros.h) should be pulled in directly instead. Would someone closer to the Mac OS X version of SDL be willing to make that change please? Thanks. Laurence Passmore Homeworld SDL @ www.homeworldsdl.org
