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
