Patch for SDL2

patch

With current SDL code you receive this warning in SDL apps:

WARNING: 140: This application, or a library it uses, is using the deprecated Carbon Component Manager for hosting Audio Units. Support for this will be removed in a future release. Also, this makes the host incompatible with version 3 audio units. Please transition to the API's in AudioComponent.h.

This is because the CoreAudio code is still using the pre-OSX-10.6 code. Since you are only supporting OS X >= 10.7 you can move away from this old code.

Attached patch seems to fix it. I only tested with Exult (exult.sf.net), with these changes it still builds and still produces sound with CoreAudio.

I'll see about making a patch for SDL 1.2x as well, since a lot of apps I build still use it and are not likely to switch unfortunately.

Patch for SDL2 - keeping support for OS X 10.5

Added a second patch for SDL2 that keeps support for OS X 10.5 so SDL2 can still be deployed for that. Adds ugly 
#if MAC_OS_X_VERSION_MAX_ALLOWED <= 1050 
lines, though. :)

Applied with this commit: https://hg.libsdl.org/SDL/rev/3115d38204aa
Comment 5 Dominik Reichardt 2016-05-23 21:39:36 UTC
I wish you could apply this to the SDL-1.2 branch as well ;)
Comment 6 Alex Szpakowski 2016-05-23 21:52:49 UTC
SDL 1.2 is itself deprecated. The audio components warning is just a bonus :)
Comment 7 Dominik Reichardt 2016-05-23 22:02:10 UTC
Yeah, I know ;)
It's just because it still receives some bug fixes from time to time...
Comment 8 Sam Lantinga 2016-10-01 21:24:46 UTC
Marking resolved.
