building webrtc APM error "NEON support not enabled" in Qt on Mac

Question

building webrtc apm in Qt on Mac ,bug it show #error "NEON support not enabled" in arm_neon.h

Answer 1

I faced the same issue building WebRTC with command lines.

Just ensure the env variables are correct

export GYP_DEFINES="OS=ios target_arch=arm64"
export GYP_GENERATOR_FLAGS="output_dir=out_ios64"

Execute the command line before each build (even after the same build)

webrtc/build/gyp_webrtc

I haven't looked deeper to find the reason.

HTH,
