Re: [Discuss-gnuradio] Raspberry PI 2 build failure

Hi Ron,

have a look at https://gnuradio.org/redmine/projects/gnuradio/wiki/Embedded

You have to native compile:

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" <source dir>


After them start make.
