No example, but the Mixer and SoundStream objects are included in the API reference (minisphere-api.txt).

As for Mac compilation, it should be the same as Linux. Dependencies are:

* Allegro 5.1.11 (I think available through homebrew?)
* libmng
* zlib

And SCons to build.  Just issue an scons at the command line and you're good to go.  The engine will be built in <checkout dir>/bin/.

If you're still confused about the mixer thing discussed on the last page, check out miniBGM.js in 1.5.2.  You can see how I used the Mixer object to implement crossfading cleanly.

homebrew doesn't have libmng and it seems to be unobtainable for me at the moment. Is there a command line switch to disable MNG support?

Not at present.  You can probably coax it to compile if you remove animation.c from the SConscript, and then comment out lines 2 and 174 of api.c.

Okey dokes, thanks.

Two errors:

obj/galileo.c:40:2: error: unknown type name 'ALLEGRO_VERTEX_BUFFER'
obj/galileo.c:393:77: error: use of undeclared identifier 'ALLEGRO_PRIM_BUFFER_STATIC'; did you mean 'ALLEGRO_PRIM_LINE_STRIP'?

Allegro through homebrew is 5.0.11, not 5.1.11 as you recommend. Is this a problem?

You need the latest Allegro (5.1.11).  What version do you have?

Edit:  yeah, 5.0.x won't work.  Not sure what to do here...

1.5.3 adds My Documents\Sphere Games to the search path for GetGameList().  Since minisphere is installed to Program Files, this makes the startup game actually useful again. :P

I just had to build it from scratch last I tried on OS X. The build is not especially pleasant on OS X, but it's manageable.

This Allegro wiki article says get it from SourceForge, but SF is in "maintenance mode" right now. Don't know how long that will last, so can't build 5.1.11 either.

I don't suppose one of you can put up the Allegro 5.1.11 and libmng source for me to download?

After building Allegro from the GitHub mirror and also removing "mng" from msphere_libs in SConscript and `brew install libjpeg`, new error:

Code: [Select]

Undefined symbols for architecture x86_64:

You have to link to allegro_main on OSX (and only OSX), I forgot about that.  Add it to the SConscript.

Just did it, compiles!

Just ran without a startup or any games (it automatically gives an Open File dialog, which is nice), got the following error on the console when canceling:

Code: [Select]

Setting up jump points for longjmp

*** set a breakpoint in malloc_error_break to debug

edit: Running a game with just `Abort("Hello, mixer!");` in the game() function results in the following error on closing:

Code: [Select]

Hm, I'll look into that.  I don't usually cancel the file dialog, so maybe I missed a bug.
