Bug with recent changes to Volk

GNU Radio
1

I believe there is a bug with the commit “volk: fixed volk rotator
kernel
to support aligned and unaligned.” I built and successfully installed
the
merge just prior to this commit just fine, but when I attempt to install
this commit I receive a “libvolk.so.0.0.0: undefined reference to
`volk_32fc_s32fc_x2_rotator_32fc_avx’” error
(Gnuradio/Volk/Builderror/rotator - Pastebin.com).
I am running on Ubuntu 12.04.

Hi,

haven’t tried that.
I’m having the same error from a fresh checkout and build directory …

Cheers,

Here a make clean also did not fix it.

Rerun cmake (or touch a CMakeLists.txt file to force cmake to rerun),
then rebuild.

As I said … new build dir and fresh checkout … so I don’t see how
that would help.

To me looks like a typo in
volk/kernels/volk/volk_32fc_s32fc_rotatorpuppet_32fc.h

  • volk_32fc_s32fc_x2_rotator_32fc_avx(outVector, inVector,
    phase_inc, phase, num_points);
  • volk_32fc_s32fc_x2_rotator_32fc_a_avx(outVector, inVector,
    phase_inc, phase, num_points);

Cheers,

Sylvain

Fixed. Long story; that was fixed and then I missed adding that fix
before checking in on my non-avx box.
