Error : NEON support not enabled, neon_vector_type attribute is not supported for this target.

[Ra]

 
Hi,

I was trying to make changes in modules/audio_processing/aec/aec_rdft.c file. I added "#include <arm_neon.h>".
In webrtc-checkout/src/out/Debug folder  I gave the command  "ninja -C ."

Then I am getting following errors
1) NEON support not enabled
2) neon_vector_type attribute is not supported for this target.

Please inform how to rectify this error.
My linux configurations is "Linux csk-csk-Desktop-System 3.13.0-76-generic #120-Ubuntu SMP Mon Jan 18 15:59:10 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux"



Full error log is given below

csk@csk-csk-Desktop-System:~/webrtc-checkout/src/out/Debug$ ninja -C .
