Can't Control FCD Parameters

I have installed 3.6.3 (from source) on a fresh install of Scientific
Linux 6.3. I basically followed the build instructions on the Fedora
page on the wiki after I added the EPEL repo to yum.

‘make’ and ‘make install’ ran without errors. ‘make test’ did not
complete- it hung at ‘27/179 Testing qa_pdu’(Is there any way to bypass
this particular test to complete the remaining tests?)

This problem I am having is that I can’t change any of the FCD
parameters. I can hear audio from the device, but I can’t change the
frequency either from a control widget or by changing it in the FCD
block in GRC.

The flow graph works properly on another computer, running an older
gnuradio, using the same FCD.

I’m looking for any ideas as to what I might have missed.

Thanks,
George

Thanks for letting us know about this, but without more information, it
is
difficult to help you.

What is the ‘older’ version of GNU Radio where this works? What OS is
that
computer? Can you post a link to the .grc files for both?

The qa_pdu bug is known about but not yet fixed. You can exclude it by
running ‘ctest -E qa_pdu’ instead of ‘make test’. See ‘man ctest’ for
more
details.

Does qthid work? If not maybe you forgot to put the
funcube-dongle.rules files into /etc/udev/rules.d/

Alex and Johnathan,

Thanks for the replies and the tip. The problem was with my udev rule,
not with gnuradio.

George

That’s good to know, thanks for the update.
I hope this part will be easier in the future when we change gnuradio
to use libfcd.
