Re: [Discuss-gnuradio] using fftw for neon with gnuradio

[Morgan Redfield]

I don't think you have to change the parameters you're giving to
./configure for gnuradio. You actually want to change the parameters
used by ./configure for fftw.

This worked for me:
./configure --enable-single --enable-neon --enable-shared
CFLAGS='-fPIC -mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp -O2'

And then I built gnuradio as normal.
