From the Trac ticket in comment #3:

"It'll be SDL1.2. Nothing to worry about just now, but perhaps someday SDL1.2 won't compile on some new macOS version."

Hopefully 2.6 with SDL2 support will be out before that day.

Doesn't seem any point keeping this ticket open, anyway.

SDL2_mixer is supported in S2_5 (--enable-sdl-mixer=sdl2), and default in S2_6 and later.

As an aside, will the SDL 2 client provide another sound plugin?

I can verify that this doesn't come from Freeciv itself, i get the exact same message when i start up ScummVM. I believe it is coming from the SDL audio library, or at least something that it touches.

Fair enough. I've opened up this Mac Ports issue to track the problem there: https://trac.macports.org/ticket/53903

I think this is likely to be something to do with the Macports packaging / build setup for Freeciv, not something we can fix upstream?

I'm pretty sure upstream code has no references to Carbon anything.

This Apple documentation seems relevant:

https://developer.apple.com/library/content/releasenotes/General/CarbonCoreDeprecations/index.html
"Carbon Core, a subframework of the Core Services umbrella framework, contains the programming interfaces of many legacy Carbon managers, in addition to various utilities. In OS X v10.8, most of these interfaces are deprecated. "

Especially the section "Components" https://developer.apple.com/library/content/releasenotes/General/CarbonCoreDeprecations/index.html#//apple_ref/doc/uid/TP40012224-CH1-SW6

"If you need to find and open audio units and audio codecs in your app, use Audio Component Services instead of the Component Manager (for more information, see Audio Component Services Reference)."

When I invoke the freeciv-gtk2 client from the command line, I see a warning message. The initial Freeciv window still appears.

% freeciv-gtk2
2017-03-02 16:30:54.886 freeciv-gtk2[99591:5959094] 16:30:54.886 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.

Freeciv-gtk2 2.0 client, freeciv 2.5.5, installed from MacPorts.
Observed on Mac OS X 10.11.6 "El Capitan".
When running a similar version of the freeciv-gtk2 client v2.5.5 on this same computer, when it still had Mac OS X 10.10.5, this message did not appear.
