Bill,
Everything works fine with the main branch of OP25. However I am trying to
incorporate some of the changes Joe made to the code a year ago or so.
After putting his changed files into the lib directory op25 compiled fine.
But when I run scope.py I get the error I posted earlier about an Undefined
Symbol.
I don't know much about python or swig so I'm hoping someone on the list
was able to incorporate his changes somehow and let me know what they did.
Thanks for your help.
James

James,
Can you also post your test.tsv file and elaborate on the specific P25
system that you desire to monitor? I have not had any issues with the
RTL SDR on OP25 scope.py running under Ubuntu 14.04 using the following
command outline to build my system. Let me know if you are running Ubuntu
in VirtualBox on a Windows machine as there are a couple of additional
pointers that I can pass along.

Here is the command I was using
./scope.py --args 'rtl' --gains 'lna:44' -f 154732500 -q 1 -S 2000000

Can you post your scope.py command line as a starting point?

Hi again all,
I'm trying to get the main branch running with some of the changes that
Joe incorporated last year. Everything compiles fine (this is a fresh
install of Ubuntu 14.04) but when running scope.py I'm getting and
undefined symbol error:
(most recent call last):
File "./scope.py", line 55, in <module>
import op25_repeater
File "/usr/local/lib/python2.7/dist-packages/op25_repeater/__init__.py",

from op25_repeater_swig import *
File

line 28, in <module>
_op25_repeater_swig = swig_import_helper()
File
"/usr/local/lib/python2.7/dist-packages/op25_repeater/op25_repeater_swig.py",
line 24, in swig_import_helper
_mod = imp.load_module('_op25_repeater_swig', fp, pathname, description)
ImportError: /usr/local/lib/libgnuradio-op25_repeater.so: undefined
symbol: _ZN8p25p2_vf12encode_dstarEPhPKi
Searching around for this does not turn up anything really. Has anyone seen this before?
Thanks,
James
