Mako bug
by lists＠lazygranch.com [op25-dev] 27 Sep '15

27 Sep '15

First post and doing a search on the group, I have a unique bug in the build process. OS is Opensuse 13.2 64 on intel hardware. Here is the output from the pybomb: ./pybombs install gr-op25 Settled on prefix: /usr/local/src/target Initializing environmental variables... Loading recipes ... /usr/local/src/target Installing packages: * mako * numpy * uhd * alsa * cheetah * wxpython * ffi * pycairo * gobject-introspection * pygobject * pygtk * sip * qt4 * pyqt4 * pyqwt5 * ssl * libevent * apache-thrift * liblog4cpp * gnuradio * libpcap * rtl-sdr * osmo-sdr * hackrf * libosmo-dsp * gr-iqbal * bladeRF * airspy * gr-osmosdr * libitpp * gr-op25 Installing from source: mako Building: (100%) [==========================================================] Build failed. Re-trying with reduced makewidth and higher verbosity. python: can't open file 'setup.py': [Errno 2] No such file or directory Build failed. See output above for error messages. --------------------------------------- The "makewidth and higher verbosity" error seems to show up on the interwebs with compiling 64 bit code on a 32 bit OS, which isnt the case here. Is this pythonbomb scheme building a private library of sorts? That is, I have a number of these programs already installed.

Scope.py Non-GUI?
by Brett Friermood brett.friermood＠gmail.com [op25-dev] 20 May '15

20 May '15

Hi everyone, I seem to recall reading something a while ago, I thought it was the RadioReference thread, where some one explained the order in which the data passes between different scripts and how to call them individually. For whatever reason I cannot find that post again. I believe there was also mention of running without the GUI. Can anybody remember seeing that and point me to it? I've looked everywhere I can think of. Thanks, Brett

Is this configuration supposed to work?
by larry.vanderjagt＠yahoo.com [op25-dev] 30 Apr '15

GNURadio installed with Pybombs OP25 installed with pybombs Versions are: gnuradio-config-info v3.7.6.1-128-g8a3ad1a5 uhd_003.008.002-131-gb850dfb5 ubuntu 14.04 LTS OP25 blocks show up in the list of blocks available for use in GNURadio Companion and decoder_bf,fsk4_demod_ff, fsk4_slicer_fb and pcap_source_b and gardner_costas_cc seem to add to the flowgraph. decoder_ff, vocoder and p25_frame_assembler cause the flowgraph to go blank with a final error in the terminal window of AttributeError: 'Block' object has no attribute 'horizontal_label'. Have done some quick searching, but have been unable to determine if this set of versions is supposed to work and what the problem may be if they are. If someone can comment (or point to a link that comments) on whether this configuration is supposed to operate it would be much appreciated. Thanks, LVDJ

recommended build versions
by singleshare＠yahoo.com [op25-dev] 29 Mar '15

29 Mar '15

Hi group, I want to build a new OP25/GnuRadio system. For those of you that may have a done a recent build, are there recommended versions of Linux and Gnuradio etc.. to use? My past experience was that different versions can cause major install headaches due to incompatibilities. I found it easier to try to get things working in a VM first so I could restore a snapshot after things got screwed up and would really like to minimize time spent to get a fresh build working correctly. Thanks for an tips!

Weird repeating audio glitch
by lukekb＠gmail.com [op25-dev] 23 Mar '15

23 Mar '15

Hi - I am using the op25_repeater blocks from the Max branch. I get a weird repeating audio glitch included with the decoded audio. I am clearly doing something wrong. Any idea where it could be? An example is here and I am attaching the file: http://openmhz.com/call/550f7f9ff44efef54e223b72 http://openmhz.com/call/550f7f9ff44efef54e223b72 The C++ code I am using is based on the scope.py code and p25_demodulator.py and is here: https://github.com/robotastic/trunk-recorder/blob/master/p25_recorder.cc https://github.com/robotastic/trunk-recorder/blob/master/p25_recorder.cc Any pointers would be huge! I am also trying to improve the CPU performance.... any thoughts there would be great. - Luke

This patch worked great and let me build on OSX. Any chance on getting it merged into that main branch?

No scope.py with new install
by Brett Friermood brett.friermood＠gmail.com [op25-dev] 18 Jan '15

18 Jan '15

Good evening everyone. I seem be having an issue with installing OP25. After installing via pybombs, scope.py as well as the rest of the scripts are missing. This is actually the second time installing on this computer. I first began with a clean install from a live CD of Debian 6. Via apt-get I upgraded to Debian 7, and eventually to debian-testing to resolve a dependency issue with libboost. All packages eventually installed then the install built op25. The only contents of ~/pybombs/src were 'uhd' and 'wxpython'. Trying again, I deleted the pybombs and target directories from /home and cloned pybombs again. I ran pybombs install and since all the packages were already installed it quickly went to building op25. Again after several hours most things are still missing. There were no errors during the build and a quick search of 'op25' and 'gnuradio' only find the .lwr files in the recipes directory, no directories anywhere. Also nothing in the syslog other than the hourly cron runs. The only thing I can possibly think of that might be related is that currently this machine is command line only. Unless I'm missing something I believe I should be able to build and even run certain parts of op25 without a GUI. This is the first time with this computer, but I've built and ran op25 before on another one. The funny thing is that there are no errors anywhere I look. Any ideas? Thanks Brett KQ9N

Re: Wireshark not capturing everything
by logitec1830＠aol.com [op25-dev] 04 Jan '15

Hi, I hadn't messed with this for a while, but I decided to re-install OP25 tonight because someone suggested that maybe the error correction had not installed properly. The re-install went smooth, but the Wireshark results are the same. In addition I notice that if I modulate (speak into the P25 radio mic) I get some errors in Wireshark as well as in the terminal window that WS is running (with a silent carrier I don't get the errors). Below are the errors. This confuses me because when I run OP25 without the Wireshark switch and in the mode where it decodes audio it sounds perfect. 22:21:13 Warn Dissector bug, protocol P25 CAI, in packet 408: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:14 Warn Dissector bug, protocol P25 CAI, in packet 461: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:14 Warn Dissector bug, protocol P25 CAI, in packet 463: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:14 Warn Dissector bug, protocol P25 CAI, in packet 464: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:14 Warn Dissector bug, protocol P25 CAI, in packet 465: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:14 Warn Dissector bug, protocol P25 CAI, in packet 468: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:14 Warn Dissector bug, protocol P25 CAI, in packet 471: packet-p25cai.c:1453: failed assertion "state != -1" 22:21:15 Warn Dissector bug, protocol P25 CAI, in packet 509: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:15 Warn Dissector bug, protocol P25 CAI, in packet 513: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:15 Warn Dissector bug, protocol P25 CAI, in packet 514: packet-p25cai.c:1453: failed assertion "state != -1" 22:21:15 Warn Dissector bug, protocol P25 CAI, in packet 515: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:15 Warn Dissector bug, protocol P25 CAI, in packet 516: column-ut Thanks.
