Filter prints ">>> gr_fir_fff: using SSE"

GNU Radio
1

Hello all,

Whenever I use a gr pre-made filter it prints something like ">>>
gr_fir_fff: using SSE
" depending on the data types.

Can anyone tell me what file I need to edit to stop the filter from
printing text? I have looked through many filter and fir .cc and .py
files, but I could not find the print statements.

Thanks,
Mike

In the source tree, doing a “grep “using SSE” * -R” produces:

gnuradio-core/src/lib/filter/gr_fir_sysconfig_x86.cc: cerr << “>>>
gr_fir_ccf: using SSE\n”;
gnuradio-core/src/lib/filter/gr_fir_sysconfig_x86.cc: cerr << “>>>
gr_fir_fcc: using SSE\n”;

gr_fir_ccc: using SSE\n”;
gnuradio-core/src/lib/filter/gr_fir_sysconfig_x86.cc: cerr << “>>>

gnuradio-core/src/lib/filter/gr_fir_sysconfig_x86.cc: cerr << “>>>

Tom,

Thanks for the quick reply. One day I will learn all the cool little
command line tricks (still a Linux newb).

Once I comment out the “cerr” commands, what do I need to do to have the
.cc file changes have an impact on my program? When I reran my program
it still printed “>>> gr_fir_fff: using SSE”. I also tried rerunning the
make file and doing make install, but that did not work either.

Thanks for the help,
Mike

That’s why I put the grep line in there. Of the many tools available in
Linux, grep is one of the most useful. Get to know it well and it will
help
you move around source code and the OS.

Where in the tree did you do the make install? You have to do it at
gnuradio-core/src/lib or higher. If you tried to do it in
gnuradio-core/src/lib/filter, it won’t rebuild and install the libraries
and
swig files properly.

If that doesn’t work for you, then you might have another version of GNU
Radio sitting around that is being used.
