System:
Jetson TX1
gcc 4.9
L4T 24.1
Problem:
I am porting my project on Jetson TX1 and getting intrinsic errors in arm_neon header file, arm_neon.h: error: identifier “__builtin_aarch64_xx” is undefined
Below is my cmake:
cmake_minimum_required(VERSION 2.6.0)

file(GLOB cuda Cuda/*.cu)

Here is the compile output:

Error limit reached.
100 errors detected in the compilation of "/tmp/tmpxft_00000a8e_00000000-7_estimate.cpp1.ii".
Compilation terminated.
As discussed in forums, I tried adding -mfpu=neon -mfloat-abi=softfp in CUDA_NVCC_FLAGS, error is then: nvcc fatal : redefinition of argument ‘machine’.
I have also tried gcc 5.x instead of 4.9 but it didn’t solve the problem.
Any suggestions please, how can I fix arm_neon.h compilation errors?
