GnuRadio, Volk and RaspberryPi 2

gnuradio/volk/kernels/volk/asm/neon/volk_32f_x2_dot_prod_32f_neonasm_opts.s:46: Error: selected processor does not support ARM mode `sbfx r11,r1,#2,#1'

No, it does. You have broken compiler.

Currently, the same Raspbian is distributed for ARMv6 RaspberryPi 1 and ARMv7 RaspberryPi 2. This means that all packages are compiled –with-arch=armv6 –with-fpu=vfp. However, this also means, that gcc assembler does not support some NEON instructions even when –mfpu=neon is set (no idea why).

You need gcc compiled with –with-arch=armv7-a –with-fpu=vfpv3-d16. For example from stock armhf Debian.

I have edited /etc/apt/sources.list so now it reads:

deb jessie main contrib non-free
deb-src jessie main

deb jessie/updates main

deb jessie-updates main

(of course pick a mirror that is in your network)

Maybe you should also change /etc/apt/sources.list.d/raspi.list to get Jessie.

apt-get update, apt-get install debian-archive-keyring, apt-get update

apt-get dist-upgrade, apt-get install gcc-4.9 gcc-4.9-base libgcc-4.9-dev libgcc1 gcc

(oh and dpkg -l | grep gcc and remove old gccs)

Continue with Installing GnuRadio from source on Debian Jessie.
