Build for Arm9V5 errors

[cs007a]

Use the C++ library method to port to the arm9v5 platform, but the following error will appear when you execute build.sh. Are there any compilation parameters to be added? Thank you !

#example-standalone-inferencing$ sh build.sh

@cs007a Could you in edge-impulse-sdk/CMSIS/DSP/Include/arm_math.h comment this out and try again?

/* evaluate ARM DSP feature */
#if (defined (__ARM_FEATURE_DSP) && (__ARM_FEATURE_DSP == 1))
  #define ARM_MATH_DSP                   1
#endif

Also which target is this? Would love to dive deeper into this…

cpu-target is Arm926ej-s

I had comment #define ARM_MATH_DSP ,
After commenting this line of code, you can continue to execute, but a new error message is encountered

then I disable comment Related code 【#ifdef ARM_MATH_DSP … #endif 】 in “edge-impulse-sdk/CMSIS/DSP/Source/BasicMathFunctions/arm_xxx_xx.c”

it works,Thanks!
