Update: when running cd ~/src/op25/python ./audio_p25_rx.py -a I was
getting this error
AttributeError: 'fft_window' object has no attribute 'plot'
FIX was to edit gr-wxgui.conf in the directory
/usr/local/etc/gnuradio/conf.d
and change the line style = auto to style = nongl
Now im getting this error when running cd ~/src/op25/python
./audio_p25_rx.py -a
Error reads "NameError: global name 'msgq' is not defined"

Hello group
Working on an install on Ubuntu 12.04 I realize there are some problems
with 12.04 but would like to help fix these issues as they occur. These are
some issues I have had so far with a fresh install of Ubuntu 12.04 and GNU
radio 3.6.0.
GNU radio was built from source code not from the install script.
Had to run sudo ldconfig after GNU radio install that I did not see
anywhere in there install directions. Anyway on to OP25
OP25
Number 1
Running ./configure in /op25/block
Configure could not find gruel_common.i in /usr/local/include/gnuradio/swig
Assuming this is due to GNU radios new location for file is
/usr/local/include/gruel/swig/
FIX was to link the directories.
sudo ln -s /usr/local/include/gruel/swig/*
/usr/local/include/gnuradio/swig/
Number 2
Using the lattes version of gcc 4.6 to compile ran into and error trying
to make the install of the op24/block.
FIX was to add
#include <cstddef>
To the file op25.cc located in op25/block/src/lib/
make and make install now worked without any errors for the /op25/block
section.
Another error I ran into was installing gr-fsk4 I realize this is not an
op25 issue but thought is was mentioning. This error was again in the
"make" section of the stall and was fixed by adding
#include <stdio.h>
to several files in the src/lib directory.
After that all the installs completed without errors however I am still
having the following issues.
1) There is no op25 decode block in GNU Radio.
2) When running
cd ~/src/op25/python
./audio_p25_rx.py -a
I get the following error
AttributeError: 'fft_window' object has no attribute 'plot'
Hope this info helps some devs and if there is any info anybody needs let
me know. In the mean time ill be working on getting this install working.
Thanks
Chris

Hi Steve,
I have been playing around for a while now using a few different ubuntu
and debian distributions. So far I've only had success with my 11.04
virtual machines. I took some wireshark captures of some P25 samples
running through Bob's flowgraph in both debian wheezy and ubuntu 11.04, the
"good" capture (
https://docs.google.com/open?id=0B8J3fNC5VR23akJ1Zl9xNkNHeHM) contains
exactly what I would expect with correct NIDs, while the "bad" capture (
https://docs.google.com/open?id=0B8J3fNC5VR23NlA2aGdWVDlHYUE) has
packets with NIDs that are all zero with the occasional 1 in the LSB. From
the packets I glanced at, the data after the NID is the same in each
capture.
I have no idea what the differences are in the dependencies between my
debian setup and ubuntu vm, but I have tried building in debian with
gcc-4.5 and boost 1.46 (instead of gcc-4.6 and boost 1.49) and have not had
any luck. I have also tried a few versions of gnuradio (3.4.2, 3.5.3 and
3.6.1) without any luck. Any other ideas to help get it working or figure
out the cause of the problem would be welcome.
Thanks,
Mark

A colleague of mine here has noted that op25 decoder seems to produce
no audio
when compiled and run on anything later than Ubuntu 11.04 for
as yet undetermined reasons. Building and running on 11.10 or later
(other mods required for 12.04) and you end up with the no audio
problem. I've suggested that he post here with any more details he may
I've used OP25 in different Ubuntu VMs and not had any problem in 11.10.
Shall try 12.04 tonight. I think that I'll set the software decoder to
be the default and that might help. There is a huge todo around the IMBE
vocoder which I've been postponing but I'll start taking a look at that
ASAP.
