Hi everyone,
I built and installed fftw with neon support for my E100 following the
instructions here: http://www.vesperix.com/arm. Now I'm trying to
recompile gnuradio to take advantage of that. Unfortunately, I get an
error when I run make.
Did you rerun configure adding -fPIC to CFLAGS? I ddi get the library to
build as a shared library.

I'm running configure with the added --enable-shared option, and then
I run make. The error i get is:
