iOS and Android builds fail, dgVector has no member 'm_ix'

[pHySiQuE]

This is the error message I get. It was working fine a month ago:

Same thing happens when building it for the iOS simulator (x86). LLVM suggests I change the member to m_x, m_y, etc.

That's because you have to define DG_SCALAR_VECTOR_CLASS for non intel cpu
there are not simd vetoc math for ARM cpu. you need to use the default scalar arithmetic class.


just add DG_SCALAR_VECTOR_CLASS to the compiler command line.

[pHySiQuE]

This should be automatic when dgtypes.h is included. Even if I define that macro in the makefile, it still doesn't work.

[Julio Jerez]

OH I see, when I look at the header I beleibe that the define si in fact automatic

Code: Select all

#if defined (__USE_DOUBLE_PRECISION__) || defined (__ppc__) || defined (ANDROID) || defined (IOS)
   #undef DG_SSE4_INSTRUCTIONS_SET
   #ifndef DG_SCALAR_VECTOR_CLASS
      #define DG_SCALAR_VECTOR_CLASS
   #endif      
#endif

the real problem is that m_ix tah are defined in the call, I am adding that now.

[Julio Jerez]

Ok I fixed the scalar vector class now.
I did test it by it should work.

ideally there should be a ARM 8 simd vector version, but I am no familiar with that, and I have never made and ARM project.
I believe there is one for Newton core 200, maybe one day I converted to core 300, but for now the scale will have to do.

I'm not too concerned with the speed of physics on ARM devices. Thank you.
