Hi Dao,

The x86intrin.h file is for Intel intrinsics, and since you are compiling for iOS or Android that runs on ARM, please use the suggested method for ARM compilation in README.md. In particular, use

cd build
cmake -DCMAKE_BUILD_TYPE=Release -DOJPH_DISABLE_INTEL_SIMD=ON ../
make

The important part here is "OJPH_DISABLE_INTEL_SIMD" that stops the inclusion of this file.

Let me know how it goes.

Kind regards,
Aous

Thanks @aous72 i have successfully make it work in ios simulator time that it run on simulator and device is aground 0.2528867721557617 seconds . I hope when i build release the time will be dropped 5 times not sure it is the case i think if we use metal engine to process it will much better . I can lose the the issue if its ok with you

[aous72]

Sure. Thank you for the feedback. Let me know if how it goes.
