Re: [Discuss-gnuradio] Compiling GNURadio on BananaPI

[Arturo Rinaldi]

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 ?

Hi,

iam trying to compile GNURadio with the build-gnuradio script. Iam running a
BananaPi (armv7 / cortex-a9) with the last raspian image for the Pi.

The building process showed me two error messages. One message was that
cmake is below 2.8.10. So i compiled and installed the last cmake 3.1 from
source. The message is gone.

When gnuradio is building i get this message:

I found the "native compiling" part at
http://gnuradio.org/redmine/projects/gnuradio/wiki/Embedded and tried out:

cmake [other options] -DCMAKE_C_FLAGS="-march=armv7-a -mthumb-interwork
-mfloat-abi=hard -mfpu=neon -mtune=cortex-a9"
-DCMAKE_ASM_FLAGS="-march=armv7-a -mthumb-interwork -mfloat-abi=hard
-mfpu=neon" <source dir>


The result is:

Any ideas ?

cheers,

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.

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  ?
