<note important>This page is now obsolete - Debian Jessie is oldstable and there are good GnuRadio packages in current versions.</note>

It's easy!

Fortunately, there are now new packages in Debian Testing/Unstable (reportedly working well) and Ubuntu 16.04. There are backports in Jessie too, but only on the amd64 architecture.

Please see GnuRadio, Volk and RaspberryPi 2 if you are compiling on Raspbian.

You need 1.2 GB RAM for linking. This means that you cannot link it on Raspberry Pi 2 or CubieBoard. Use local swap, NBD swap or cross-compiling () for it (scroll down for more info).

After installation is complete, run volk_profile (or volk_profile -i 512 on slow machines). It will benchmark and select the best vectorized kernels for your machine. Speedups of 150-190 % have been reported.

<note warning>grcc s broken in current master, patch and more info here.</note>

<note tip>This patch for gr-osmosdr works around current bug in gnuradio: https://gnuradio.org/redmine/issues/775</note>

It is not possible to link it on systems with 1 GB RAM. Unfortunately, this is what most ARM boards have.

Except for nbd swap, you can try mounting the filesystem on some other machine. But it's probably not ARM and cross-compiling is PITA (you need for example the entire armhf Boost!). You can run ARM code in Qemu software emulator. This is going to be slow. Do

cp /usr/bin/qemu-arm-static /mnt/foo/usr/bin

and then just chroot there and run compilation as usual.

I will occasionally release prebuilt binaries (rtl-sdr + gnuradio). They are compiled with -march=armv7-a -mfloat-abi=hard -mfpu=vfpv3-d16 and were tested on Debian Jessie on Radxa Rock Pro and Orange Pi PC. RaspberryPi should have the very same architecture.
