[Discuss-gnuradio] Compiling GNURadio on BananaPI

[Andreas Ladanyi]

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 ?
