/usr/lib/gcc/arm-linux-gnueabihf/8/include/arm_neon.h:6742:10: fatal error: You must enable NEON instructions (e.g. -mfloat-abi=softfp -mfpu=neon) to use these intrinsics.

I setup opencv with neon vfpv3 neon flags and adjust the main code as getting webcam stream.
Altough ı add -mfloat-abi= hard flag , I encounter this problem . Which flags I add in c make build to enable neon intrinsic ?
