Hi Volker,
Yes sir, I've added throttles, and tried all of the provided demo's. I've also
done more research, and further down the list are people talking about the same
thing...
http://lists.gnu.org/archive/html/discuss-gnuradio/2013-06/msg00373.html
so I have hope it's not just me... :)
Thanks,
Mark
May be a silly question, but does your flow graph contain >a throttle block ?

Hi,
I just installed GNURADIO from git, onto a brand new install of Mint 15.
I followed the following instructions:
http://bgamari.github.io/posts/2013-06-15-hackrf.html
gnuradio-config-info -v
3.7.0git-143-gad1d52fd
With Python 2.7, I was able to get everything compiled and installed.
The CMakeLists.txt in GNURADIO I had to tweak line(168)
to: find_package(PythonLibs 2.7) for it to include Python support.
My environment vars:
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:
PYTHONPATH=:/usr/local/lib/python2.7/dist-packages
I built GNURADIO with the following cmake:
cmake -DPYTHON_EXECUTABLE=/usr/bin/python2.7
-DPYTHON_INCLUDE_DIR=/usr/include/python2.7
-DPYTHON_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython2.7.so.1 ../
I fire up gnuradio-companion and try a simple example dial_tone.grc. I
click generate, then execute, I see the standard "Executing
..."/tmp/dial_tone.py" "Using Volk machine: svx_64_mmx" etc... No other
errors. My problem is, no QT/WX GUI elements show up.
I built a simple grc file with a QT slider(and nothing else), and this
worked.
I tried a basic signal source, through a throttle right into a QT FFT
GUI element. The grc runs, no errors, yet the physical display of the
FFT fails.
I have on another box gnuradio 3.6.5 and all of this worked fine. I
compared qt/wx/python debs and verified both machines have similar packages.
The key common factor in this problem is if i remove the signal sources
and sinks, the QT/WX basic sliders will show... Perhaps there is
something wrong with my version of gnuradio and how it handles
inputs/outputs, killing GUI display? I've also tried compiling against
python3, 3.3 and 3.3m...no luck.
Is there a way I can enable an extra layer of debug into GRC for me to
see what it's doing??
I've tried running /tmp/dial_tone.py directly and it run's, but no audio
or gui elements display. Another hint which may help, is a basic audio
source to audio sink, set to "pulse" does not output audio into my
speakers. The audio does work with the OS audio tests, and I am running
pulseaudio.
I would like to stay with the latest GNURADIO simply to support my
HackRf board, in which the HackRf gr-osmosdr library seems to only
support the latest version. I tried with 3.6.5 and it failed to compile...
Thank you for any insight,
Mark
