SDL_mixer on Android

I got them from cocos2d and patched to work with SDL
https://code.google.com/p/hedgewars/source/browse/#hg%2Fmisc%2Flibtremor

I never ever got the ones from xiph.org to work on ios/android...
On the other hand, on the same svn repo there are so many tremor versions it's hard to pick the right one!

Where did you got your libtremor sources btw?

Hmmm, you probably have some kind of patched libtremor. Just look at
misc.h in seems-to-be-official repo:
http://svn.xiph.org/trunk/Tremor/misc.h

While compiling libtremor for android I'm getting this error:

jni/tremor/misc.h:57:7: error: redefinition of 'union magic'
jni/tremor/misc.h:47:7: note: originally defined here

It seems that BYTE_ORDER is not defined and union magic is defined twice:

#if BYTE_ORDER==LITTLE_ENDIAN
union magic {
struct {
ogg_int32_t lo;
ogg_int32_t hi;
} halves;
ogg_int64_t whole;
};
#endif

#if BYTE_ORDER==BIG_ENDIAN
union magic {
struct {
ogg_int32_t hi;
ogg_int32_t lo;
} halves;
ogg_int64_t whole;
};
#endif

Where BYTE_ORDER should be defined for libtremor? Can someone help me
with this? Thanks in advance.
Regards, Alexey

Can somebody really experienced with SDL_mixer on android handle this?
It will save a lot of time for all others ;)

Maybe it is a good idea to provide prebuilt android binaries for any
SDL_mixer dependencies (libtremor, libmikmod) just like we have
prebuilt frameworks for OS X in Xcode/Frameworks?

Thank you for your response. I'll look through files you attached in
next few days. But in my opinion there should be some README.android
in SDL_mixer repo for such cases.

Just to add that libtremor does *NOT* need libogg, it implements
vorbis and
vorbisfile, that is all SDL_Mixer needs, at least in the newest
version (do
not use the bugged version distributed with cocos2d).

HG versions of SDL_mixer have an Android.mk, don't know about the
older
ones, but I'd stick with the HG one since ideally you should use the
latest
SDL HG (and I suggest so, mostly for the new touch api that does not
need
SDL_GetTouch() ).

If you want to see an example of SDL_mixer on android you can download
the
SVN of my soccer game (Eat the Whistle,
https://play.google.com/store/apps/details?id=org.ggsoft.etw ), that
is
located here:

http://etw.svn.sourceforge.net/viewvc/etw/trunk/

If it can be useful to you, I've included in the SVN also a full tree
of
libtremor, with a premade Android.mk.
