I must correct a detail. The datasheet tells me that bananapi has a
Cortex-A7.

cat /proc/cpuinfo:

I don’t know that it’s a definite fix for this, but I was going to
suggest making sure the tune settings fit your processor. If that’s
not the case we can look around for a suitable change. Keep us
updated.

processor : 1
Hardware : sun7i
cmake is below 2.8.10. So i compiled and installed the last cmake 3.1 from

volk/lib/CMakeFiles/volk.dir/__/kernels/volk/asm/neon/volk_32fc_x2_dot_prod_32fc_neonasm_opttests.s.o

[ 2%] Building ASM object

‘volk/lib/CMakeFiles/volk.dir/__/kernels/volk/asm/neon/volk_32f_x2_dot_prod_32f_neonasm_opts.s.o’

The result is:
make[2]: ***
Any ideas ?

Hi Nathan,

cmake …/ -DCMAKE_C_FLAGS="-march=armv7 -mthumb-interwork
-mfloat-abi=hard -mfpu=neon -mtune=cortex-a7"
-DCMAKE_ASM_FLAGS="-march=armv7 -mthumb-interwork -mfloat-abi=hard
-mfpu=neon

results in the message:

Is it possible that ARM isnt supported in volk ?

Instead of building on the board itself, wouldn’t be better to compile
the
source code on your working machine by exporting the toolchain compilers
by
means of a simple script ?

Thanks

I already have a swap partition with 2 GB.

I tried out your suggestion. The result is the same:

With the latest LUbuntu (instead of the latest raspian like in my last
mails) version of Banana Pi the following error results when compiling
gnuradio with the gnuradio build-script:

I think when I built it I used:

cmake -DCMAKE_CXX_FLAGS="-mcpu=cortex-a7 -mfpu=neon-vfpv4
-mtune=cortex-a7 -funsafe-math-optimizations" …/ -Wno-dev

I also had to enable swap space because the bpi doesn’t have enough
memory for some of the compile stages:

sudo dd if=/dev/zero of=/sata/swapfile bs=1024 count=1024k
sudo mkswap /sata/swapfile
sudo swapon /sata/swapfile
free -m

Thanks

Yes. As has already been mentioned on this thread, on these devices, you
need to set some extra cmake flags. See our Embedded page and the
section
on Native Compiling.

http://gnuradio.org/redmine/projects/gnuradio/wiki/Embedded

Even with this information out there, I still don’t understand why
people
try and natively compile GNU Radio on these devices…

Yes, i know this. But this doesnt work on the raspian OS on Banana. On
Lubuntu for Banana this works now with this extra cmake flags.

Even with this information out there, I still don’t understand why
people try and natively compile GNU Radio on these devices…
Because to make the experience that native compiling on these devices is
terrible

In the future i will use cross compiling.
