GNU radio with 1 - qa_test_all failed

Hello all

I am installing GNUradio in two boards, one is Odroid XU3, with Ubuntu
14.04
system. The other one is Hummingboard i2ex with Debian Jessie system.

I build from source with version 3.7.8 in git. Both boards have same
issue
when I make test.

$ make test
Running tests…
Test project /home/gnuradio/build
Start 1: qa_volk_test_all
1/1 Test #1: qa_volk_test_all …***Failed 5.11 sec

0% tests passed, 1 tests failed out of 1

Total Test time (real) = 5.12 sec

The following tests FAILED:
1 - qa_volk_test_all (Failed)
Errors while running CTest
make: *** [test] Error 8

I run ctest -V _R qa_volk_test_all, I attached the output in the ctest
file

Thank you so much. I really appreciate your help! ctest.rtf

Hi Shaun,

This is the first I’ve seen something like this in a while. It’s
definitely
memory corruption in our QA. Can you provide some information on how you
are building VOLK? Are you cross-compiling or native? What cmake flags
are
you providing? What compiler are you using? Is your OS soft-float or
hard-float?

If you just want to get rid of this problem try removing orc and
rebuilding
VOLK.

PS, in the future can you send text through a pasting service like
fpaste.com? I’m a little uneasy about downloading files from weird
websites
like nabble.com.

Hello Nathan

Can you provide some information on how you are building VOLK?
I download the VOLK file from the git, cause the master of gnuradio does
not have volk included. https://github.com/gnuradio/volk And then I just
follow the instruction in the building website

$ mkdir build
$ cd build
$ cmake …/
$ make && make test
$ sudo make install

Are you cross-compiling or native?
I am building it native. I actually don’t know how to cross compile
this.
If you can give me a website to learn, that would be awesome.
What cmake flags are you providing?
I used the cmake from https://gnuradio.org/redmine/issues/692 if I
just
use cmake, building will fail in the volk test_all step.
Here is my cmake command for the pi:

@ cmake -Dhave_mfpu_neon=0 -DCMAKE_CXX_FLAGS:STRING="-march=armv6
-mfpu=vfp
-mfloat-abi=hard" -DCMAKE_C_FLAGS:STRING="-march=armv6 -mfpu=vfp
-mfloat-abi=hard" …/
But it also works with just:
@cmake -Dhave_mfpu_neon=0 …/

What compiler are you using?
I don’t know the version of my compiler. I use debian jessie in
Hummingboard, you probably know which version it is. And I use the image
from this website for Odroid.
http://odroid.com/dokuwiki/doku.php?id=en:xu3_release_linux_ubuntu

Is your OS soft-float or hard-float?
I don’t think I can answer this question. Sorry

Could you please tell me how to remove ORC. I googled ORC, the only
result
I get is from this website,
https://gnuradio.org/redmine/projects/gnuradio/repository/revisions/05161c9f48acf448d31abd88a5378608213e3574
where is ORC? I cannot find ORC file in my VOLK. I need more details for
how to remove ORC.
I really appreciate your help!

Hi Shaun,

You need to make sure that the compiler flags you are using make sense
for
your hardware and libraries you link against. For example, The
ODROID-XU3
uses a cortex-a7 processor which uses an armv7 architecture, but you are
telling your compiler that your architecture is armv6 (you copied
instructions intended for a raspberry pi). You also tell it that you are
targetting a hard-float ABI; you need to make sure that is actually the
case or you will get some wrong results and potentially segfaults (it’s
unpredictable what will happen, but it will only fail at runtime). This
explains why your log has no NEON protokernels running. The
-Dhave_mfpu_neon=0 line is just telling VOLK that you have no NEON unit,
which you probably don’t want and has little influence on ORC.

Assuming you installed orc with your package manager, just remove it
with
your package manager. If you’re on a debian based system that’s ‘apt-get
remove orc’, or whatever the orc package(s) are called.
