Re: [Discuss-gnuradio] 'asm' error while compiling on Beaglebone

[Aylons Hazzud]

Inspired by a thread in this discussion list [1], I have tried the
following command for cmake:

cmake -DENABLE_GRC=False -DENABLE_GR_QTGUI=OFF -ENABLE_GR_WXGUI=OFF
CFLAGS="-mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp
-ftree-vectorize -ffast-math -O3 -g" CXXFLAGS="-mcpu=cortex-a8
-mfpu=neon -mfloat-abi=softfp  -ftree-vectorize -ffast-math -O3 -g"

No luck, yet :c/
