I must correct a detail. The datasheet tells me that bananapi has a
Cortex-A7.
cat /proc/cpuinfo:

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 ?
