Newton on Android NDK (ARM-NEON)

[Krystian]

What NDK version are you using? I've tested it with r5c and r6b (you can - and IMO you should - use always latest NDK, even when building for older API, but of course you cannot use new libraries which are available on newer APIs).

Only one reason would be inconsistent "#ifdef ANDROID" vs. "#ifdef __ANDROID__" (coreLibrary_200/source/core/dgTypes.cpp) - readmore
So try to find #ifdef ANDROID (in dgTypes.cpp after patching) and change it to #ifdef __ANDROID__

It this will help, I'll change that #ifdef in patch to #if (defined(ANDROID) || defined(__ANDROID__). Waiting for your reply (also with info what version of NDK you are using).

Edit: It looks like __ANDOIRD__ should be used. readmore

I think you should wipe this

Code: Select all

-D_LINUX_VER -D_LINUX_VER_64

i use

Code: Select all

LOCAL_CFLAGS := -ffast-math -freciprocal-math -funsafe-math-optimizations -fsingle-precision-constant -D_SCALAR_ARITHMETIC_ONLY
LOCAL_CFLAGS += -DANDROID_NDK

I've updated patch http://code.google.com/p/newton-dynamic ... tail?id=16 (you should be of course using latest sources of NGD from SVN)
Definition of _LINUX_VER_64 is not needed if you patched dgTypes.cpp.
Also you should use latest NDK (for now it's r6b).

I am using Newton 2.33, found here:
http://code.google.com/p/newton-dynamics/downloads/list

I would rather not deviate from the official source code. I do not want to add unofficial patches. dgTypes.cpp doesn't even have any mention of ANDROID in it, so I don't know where your patch is supposed to go.

I tried adding _LINUX_VER and _LINUX_VER_64 to LOCAL_CFLAGS, and it's still complaining about the _m128 thing.

Hey, of course that dgTypes.cpp doesn't even have any mention of ANDROID in it, because Newton never had any official support for Android (and will never i think, so it's up to you to make some effort).
Please read about how to use patch.exe with cygwin, or with tortoise. That's the deal with opensource, you have to make

[pHySiQuE]

Any idea when it will be officially supported for Android? I don't want to branch off with my own version of the source and then have to redo all my changes when the official source gets updated.

[Krystian]

If you use version from SVN and apply this you will be able to revet changes from this patch with just 3-4 mouse clicks (in case of W.)
And if this patch will be applied by Julio to NGD, then after you make 'SVN Update' that changes will be merged pain-less.

"I don't know where your patch is supposed to go."
If you want I can make a screencast.

Thank you. I will make sure I can get it working on iOS and Mac first, and then use this patch for Android if those work also.

Now my project all compiles, but at the very last step, after about 300 files compile for 20 minutes, I get this error:

Argument list too long

WTH?

[Julio Jerez]

300 hundred files? the engine is only 68 files.

I am trying to compile Newton into my game, not build it as a static library.
