Gr_fir_fff: using 3DNow! core dump

I have a program that uses gnuradio to work with a HiQSDR.

The first time I fired up qsdr it worked.
Closing it down and re-opening later I got the error. A reboot of the
system didn’t solve it.

$ qsdr
starting server
Using Volk machine: sse4_a_64

gr_fir_fff: using 3DNow!
terminate called after throwing an instance of ‘std::runtime_error’
what(): unpaired unlock() call

Sid,

What version of GNU Radio are you using for this? You should try to
pull in the filter from the filter module instead of from gr:

from gnuradio import filter
fir = filter.fir_filter_ccf(decim, taps)

Also, what is your processor?

This is the output from the openSUSE boxes and the CPU flags which don’t
include sse4_a.
Later I’ll try rebuilding gnuradio with “-msse3” to see if that helps.

Sid,

Have you tried using the filters out of the filter module, yet? Those
filters use VOLK for SIMD instead of the hand-crafted stuff that in
the gr filters. That might help. Besides which, we’re removing those
filters, so moving to the new filter module will keep you more
compatible as we go forward.

Thanks Tom,
The qsdr design is not mine.
I’ll pass this info on to the author.

Can’t you change the code in qsdr yourself? If it’s based on GNU
Radio, you should have the source code and making this change is
pretty trivial (the interface to the filter functions is the same; you
just get them from a different module).

OK Tom,
I’ll have a check.
