Problems building GNURadio

GNU Radio
1

Hi:
I am having problems building gnuradio on armV7 that I cannot figure
out. I am using pybombs.
Here is a snapshot of the errors during the build:

Can anyone point me in the right direction?

Thanks,

I’m not sure of the problem, except that I would expect this to happen
if you did the following steps:

  1. built GNU Radio from source roughly 3 weeks ago or later
  2. updated to a new revision
  3. run make without running cmake

Do you see any files in the gnuradio
$buildir/volk/lib/CMakeFiles/volk.dir/__/kernels/volk/asm/neon/ ?
You can try using pybombs clean gnuradio, and then try building again.

Native compiles don’t pick up the proper C and ASM flags. Here’s what I
had
to set to build natively on a Tegra:

cmake [other options] -DCMAKE_C_FLAGS=“-march=armv7-a -mthumb-interwork
-mfloat-abi=hard -mfpu=neon -mtune=cortex-a9”
-DCMAKE_ASM-ATT_FLAGS=“-march=armv7-a -mthumb-interwork -mfloat-abi=hard
-mfpu=neon”

I might have gone overboard with them, like it’s probably not necessary
to
tell the native C compiler what its arch is, but I mostly carried this
over
from our OE cross compiler work and it built and ran fine this way.
