Re: [Discuss-gnuradio] Compiling GNURadio on BananaPI

[Tech]

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
