Running Newton (on platforms other than Windows)

[pHySiQuE]

I'm very happy to have Newton compiling for Mac, iOS, and Android, but the time has come where I need to start using it on these platforms.

To make Newton compile for Mac, I changed line 26 of dgtypes.h to this:

Code: Select all

#ifndef _MAC_VER
    #if !(defined (__USE_DOUBLE_PRECISION__) || defined (__ppc__))
        #define DG_BUILD_SIMD_CODE
    #endif
#endif

When I run my program, I get this error:

Can you tell me what the current status of this is? Thank you.

For mac I do not have a xcode text that I can use to debug the atomics. Ther are only tow atomic that nee to be implemented in OS10, unfornually tread do no coem with cross platfrpom atomics
therfore they have to be implemented as natove funtion in each OS.

I check in a version with the mutiothread code in emulation. sync to SVN, and next time I see if I can implement the atomics.

[pHySiQuE]

That was fast, thanks!

My program calls NewtonUpdate() without crashing, so that's a good sign. Tomorrow I will try out some actual physics on the other platforms. Thank you!

Here are my changes as an SVN patch:

It builds on Android now. No idea if it will run, yet.

[pHySiQuE]

I've got an object dropping in space on Android!

[pHySiQuE]

On OSX and iOS, when NewtonUpdate() is called, the program gets stuck in that call, and never comes out. I have DG_THREAD_EMULATION defined in both projects.

Hey I thoink this is good news, I had a hunch that the GCC atomic mugh also work on OSX, so I repelce then and compile, and it work.

now I made the changes and everything is unified for Mac and Linux

Code: Select all

DG_INLINE dgInt32 dgAtomicExchangeAndAdd (dgInt32* const addend, dgInt32 amount)
{
   // it is a pity that pthread does not supports cross platform atomics, it would be nice if it did
   #if (defined (_WIN_32_VER) || defined (_WIN_64_VER) || defined (_MINGW_32_VER) || defined (_MINGW_64_VER))
      return _InterlockedExchangeAdd((long*) addend, long (amount));
   #endif

   #if (defined (_LINUX_VER) || defined (_MAC_VER))
      return __sync_fetch_and_add ((int32_t*)addend, amount );
   #endif
}

DG_INLINE dgInt32 dgInterlockedExchange(dgInt32* const ptr, dgInt32 value)
{
   // it is a pity that pthread does not supports cross platform atomics, it would be nice if it did
   #if (defined (_WIN_32_VER) || defined (_WIN_64_VER) || defined (_MINGW_32_VER) || defined (_MINGW_64_VER))
      return _InterlockedExchange((long*) ptr, value);
   #endif

   #if (defined (_LINUX_VER) || defined (_MAC_VER))
      __sync_synchronize();
      return __sync_lock_test_and_set((int32_t*)ptr, value);
   #endif
}

This important because some of the new mobile device are muticores. tha chnage make it should run on all mobile devices in multithreaded mode.
Please try again and see if it builds, I am also trying to make a OS Cocoa sanbox demo for Macs.

I get this error in Xcode now:

ld: duplicate symbol exp_2(int) in /SVN/Leadwerks3D/Engine/Projects/OSX/build/Leadwerks3D.build/Debug/Leadwerks3D.build/Objects-normal/x86_64/dgAABBPolygonSoup.o and /SVN/Leadwerks3D/Engine/Projects/OSX/build/Leadwerks3D.build/Debug/Leadwerks3D.build/Objects-normal/x86_64/dg.o for architecture x86_64

And Eclipse gives me this wall of text. Looks like it's related:

BTW, I have proof Newton was running on Android, at one point:

At this point, I am trying to go through revisions and find the last one that worked. Revision 2216 is when the duplicate symbol exp_2 error began appearing...

[Julio Jerez]

revision 2216, The lastest revision is 2246

[pHySiQuE]

It's building and running now, on all platforms. Thanks for your help. I'll post a tutorial later, but right now I am taking a nap...
