gnuradio error #480

nocomp · 2019-09-17T09:14:02Z

hi folks,
first of all thxx for this great tool i used to have working, but no idea what i ve did, almost spend a day to get it back on rails with no luck.
you are my last chance
here is the situation:
i ve installed on last kali version (used to work) using apt-get and now when i launch it i get:

nocomp@8uR34ud3sL1c0rn35:~/tools/sdr/gr-gsm$ grgsm_scanner
Traceback (most recent call last):
File "/usr/bin/grgsm_scanner", line 24, in
from gnuradio import blocks
ImportError: No module named gnuradio

so i ve pulled the git and when i try to build it i get for cmake ..

CMake Warning at CMakeLists.txt:135 (find_package):
Found package configuration file:

/usr/lib/x86_64-linux-gnu/cmake/gnuradio/GnuradioConfig.cmake

but it set Gnuradio_FOUND to FALSE so package "Gnuradio" is considered to
be NOT FOUND. Reason given by package:

Gnuradio could not be found because dependency Volk could not be found.

CMake Error at CMakeLists.txt:150 (message):
GnuRadio Runtime required to compile gr-gsm

i ve uninstall and reinstall gnuradio gr-gsm many times still same error :'(

grc is in /usr/lib/python3/dist-packages/gnuradio/grc

and here are my paths:

sh -c 'set | grep -i path'

all kind of helps are welcome, receiving my limesdr in 2 days and my whole world is broken... #HELPPPPPPPPPPPPPPPPPP

Hi @nocomp,

you are my last chance
here is the situation:
i ve installed on last kali version (used to work) using apt-get and now when i launch it i get:

It's quite typical for Kali (and other rolling distributions) something that have worked yesterday to no longer works today.

In Debian Testing and Kali they have updated gnuradio to 3.8 but still have not updated all dependent packages.

so i ve pulled the git and when i try to build it i get for cmake ..

We are working on adding support for gnuradio 3.8 in #475. Try building from maint-3.8 branch from my fork and have a look at Kali.docker that is used in our travis builds

As I said in my previous message you need to checkout and build maint-3.8 branch from my fork.

nocomp · 2019-09-17T12:15:38Z

oh i thought i just had to git clone your repo and then go to the install process like the on in installation page.
do you have a tutorial i can follow?

You need to install liborc-dev and not liborcus-dev nor liborc-0.4-0. You could find the full list of packages in the docker file.

apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y \

From the top gr-gsm directory you need to execute

docker build -f tests/dockerfiles/Kali.docker .

Note that there is a dot (.) at the end of the command, you need it.

hi
thxx a lot for your reply
i ve been able to compile following your advice, but when i run it, i get this module error:

nocomp@8uR34ud3sL1c0rn35:~/tools/sdr/gr-gsm/build$ grgsm_scanner
Traceback (most recent call last):
File "/usr/local/bin/grgsm_scanner", line 33, in
import grgsm
ModuleNotFoundError: No module named 'grgsm'

;
what did i do wrong?

compilation worked like a charm with your fork, well done!
thxx for your time
cant find using pip or apt any module named like this

You need to add /usr/local/lib/python3/dist-packages/ to PYTHONPATH, in your shell execute

export PYTHONPATH=/usr/local/lib/python3/dist-packages/:$PYTHONPATH

or to make it permanent add this to your shell profile (~/.bashrc or ~/.bash_profile)

That's needed because of this debian's patch

nocomp · 2019-09-17T17:00:44Z

yeaaaaaaaaaaaaaaaaaaaaaaaaaa works like a charm,
thank you so much:!!!!
the docker installed work, but wont use it, need to fgure out how clean that in order to get some hd space.
thx again for your time, truelly appreciate.
next challenge: decode sms :))

velichkov · 2019-09-17T17:10:16Z

but wont use it, need to fgure out how clean that in order to get some hd space.

Run docker ps -a and then for every CONTAINER ID or NAMES run docker rm 895e7a7b445d gnuradio-ubuntu-16.04 ....

Then run docker images and for every IMAGE ID run `docker rmi c3e52da505c6 ...

in fact there is an issue (sorry again)
when i grgsm_scanner with your fork version i get only one result
if i grgsm_scanner on another computer that has it preinstalled i get 14 results

any idea why?

thxx for your help

Do you use the same SDR device with the same antenna on both computers?
What are the hardware specs of the two computers - CPU, RAM, USB port types, etc...?

nocomp · 2019-09-23T12:05:57Z

hi,
yes same sdr device and same antenna and same computer lenovo x280 in multiboot
your fork on kali boot, and the normal version on HamOS
8gb ram USB 3 ssd hd i3 8th gen

velichkov · 2019-09-23T12:34:40Z

and the normal version on HamOS

What is the exact version?
What SDR device do you use and how is connected to the host - USB 2/3 or ethernet?

nocomp · 2019-09-23T12:50:40Z

hamos runs 0.42.2-1+b2

kiransgk1si18lvs04 · 2020-02-11T12:49:44Z

Hi @anandpandey786
Use this command grgsm_livemon_headless --args=rtl -f 952.4M
you have missed headless in command.

anandpandey786 · 2020-02-11T15:17:17Z

Thanks for reply
I deliberated omitted headless .... wanted to see the pixmap/monitor
Every thing is running in my build but despite that gsm data is not visible on monitor tried several frequencies...

velichkov · 2020-02-11T17:48:08Z

Hi @anandpandey786,

avahi bad state error was also seen which was eradicated by args argument

What args did you used to solve the avahi errors?

but invalid source error...what is the reason for that...

I don't know.

livemon monitor is running but no gsm data being captured so far
Every thing is running in my build but despite that gsm data is not visible on monitor tried several frequencies...

First try finding a frequency of a nearby C0 BCCH channel using grgsm_scanner and then specify that frequency when running grgsm_livemon. Also make sure there are GSM networks where you live in the bands supported by your RTL device.

Hi,

I'm using a RTL2838 SDR with Ubuntu 16. I followed your installation instructions from the osmo website hyperlink from ptrksky grmgsm github repository to the letter.

Everything works except when I run grgsm_livemon I keep getting 0's displayed.

grgsm_scanner returns no results when scanning all available bands.
Kalibrate-rtl RETURNS GSM stations and no other bands.
Kalibrate has given me my ppm.

Rtl_test returns no errors in my signals. I have changed sample rates, used VM and a desktop with Ubuntu 16 returning the same results.

What else can I do?

Do you have a suitable antenna attached to your RTL dongle? Are you sure that there are GSM networks in the area where you are and in the band you are searching in? In case you are inside in a big building try moving near a window or outside.

In case you live in USA note that AT&T stopped their 2G network in the GSM850 band back in 2017 and for T-Mobile network in the GSM1900 band you need a dongle with Elonics E4000 tuner or another SDR device that supports that band.

Hi @velichkov
I am successful in installing grgsm from your maint branch and I am get all BCCH data like MCC,MNC,LAC and some other things, but there is problem when designing simple gui application using tkinter. I am attaching code below

import tkinter as tk
import subprocess
import shlex

def BCCH():
cmd=["grgsm_scanner","--args=rtl","-b","GSM900"]
output= subprocess.check_output(cmd)
result=print('>', output)
# put result in label
result['text'] = output.decode('utf-8')

my_gui = tk.Tk()
my_gui.geometry('600x600')
my_gui.title("Get output inside GUI")

tk.Button(my_gui,text="GET BCCH", command=BCCH).pack()

label for BCCH result

result = tk.Label(my_gui,font=50)
result.pack()

my_gui.mainloop()

I am getting excemptions thinking that some files are missing.
Exception in Tkinter callback

Hi @kiransgk1si18lvs04,

ModuleNotFoundError: No module named 'grgsm'

Make sure you are running your application with the same python version that gr-gsm and gnuradio was compiled with (most probably python3), add the following as the first line in your scripts.

#!/usr/bin/python3

If it still does not work you may need to add the path where the gr-gsm's python module was installed to the PYTHONPATH environment variable, see #480 (comment)

P.S.
Please next time try using markdown to format your messages as right now they are hardly readable and avoid hijacking unrelated github issues.

kiransgk1si18lvs04 · 2020-04-10T11:41:46Z

Hi@velichkov
I have added python path permanently by using your instruction.

Hi @kiransgk1si18lvs04,

pythonpath added still program is not working.

What do you mean by "not working"?

Double check that the environment variable is exported correctly and that grgsm module is installed in /usr/local/lib/python3/dist-packages/

echo $PYTHONPATH
ls /usr/local/lib/python3/dist-packages/grgsm/

kiransgk1si18lvs04 · 2020-04-27T09:59:42Z

sorry I am noob in this case @velichkov
grgsm is inside the folder of `/usr/local/lib/python3/dist-packages/'
grgsm_scanner works on command terminal in kali linux, but not works on above program.

The error details are,

Traceback (most recent call last):

How do you start the above program? In your program somewhere at the top add the following and give me the output

import sys
print(sys.path)

and also give me the full output of ls /usr/local/lib/python3/dist-packages/grgsm

By using .py file

How exactly? Do you run it from some IDE or from the command line?

['/home/kali', '/usr/bin', '/usr/lib/python37.zip', '/usr/lib/python3.7', '/usr/lib/python3.7/lib-dynload', '/usr/local/lib/python3.7/dist-packages', '/usr/lib/python3/dist-packages', '/usr/lib/python3.7/dist-packages']

The /usr/local/lib/python3/dist-packages/grgsm is not in sys.path and this explains why it can't find the grgsm module.

This is bash_profile

export PYTHONPATH=/usr/local/lib/python3/dist-packages/:$PYTHONPATH

Try adding the export line to your ~/.profile and logout and login again. See also https://help.ubuntu.com/community/EnvironmentVariables#A.2BAH4-.2F.profile

I will run through python idle, and make a new file of .py and the version of python is 3.7.6

Try adding the export line to your ~/.profile and logout and login again. See also https://help.ubuntu.com/community/EnvironmentVariables#A.2BAH4-.2F.profile

I studied it, and added path to .profile , I am getting same error output

sorry for attaching screen shot, to make convenient I have attached.

Try running your program from the command line - python3 ./bcch.py.

I studied it, and added path to .profile , I am getting same error output

Did you logout or reboot after adding it?

If yes then most probably the python idle reset the PYTHONPATH environment variable. I'm not familiar with this IDE and I don't know how to correctly set the PYTHONPATH in it.

Hi @velichkov
I got solution for that, I just copied grgsm module to system located python dist packages.

sudo cp -r /usr/local/lib/python3/dist-packages/grgsm/ /usr/lib/python3/dist-packages/

Thanks for support, I have a last question
when I type kal -s GSM900 it shows power 79296 that in terms of thousands, but when type grgsm_scanner in terminal its showing in terms of 10's ie 47 or 50 like that, Is that a signal strength

kal -s GSM900
Found 1 device(s):
  0:  Generic RTL2832U OEM

Using device 0: Generic RTL2832U OEM

Hi @kiransgk1si18lvs04,

sudo cp -r /usr/local/lib/python3/dist-packages/grgsm/ /usr/lib/python3/dist-packages/

I do not recommend doing this. If you can't find how to modify the PYTHONPATH in your IDE then in my opinion the next best thing is to create a symlink in /usr/local/lib/python3.7/dist-packages that points to /usr/local/lib/python3/dist-packages/grgsm/

sudo ln -sf /usr/local/lib/python3/dist-packages/grgsm/ /usr/local/lib/python3.7/dist-packages/grgsm

when I type kal -s GSM900 it shows power 79296 that in terms of thousands, but when type grgsm_scanner in terminal its showing in terms of 10's ie 47 or 50 like that, Is that a signal strength

My understanding is that these numbers are all relative and you can't compare them directly.
