gnuradio error

[nocomp]

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' DBUS_SESSION_BUS_ADDRESS='unix:path=/run/user/1000/bus' PATH='/home/nocomp/.local/bin:/home/nocomp/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/usr/local/go/bin' WINDOWPATH='2'

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

thxx for your time

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

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

I am running the scripts on python 3.7.6

still doesn't work.

[kiransgk1si18lvs04]

Hi@velichkov I am using python 3.7.6. pythonpath added still program is not working.

#!/usr/bin/python3
import tkinter as tk
import subprocess

def BCCH():
    while True:
        try:
                cmd=["grgsm_scanner","--args=rtl","-b","GSM900"]
                output= subprocess.getoutput(cmd)
                result=print('>', output)
                # put result in label
                if not output is None:
                    result['text'] = output.decode('utf-8')
        except subprocess.CalledProcessError as exc:
           print(exc.returncode)

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

my_gui.mainloop()

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]

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):
  File "/usr/local/bin/grgsm_scanner", line 33, in <module>
    import grgsm
ModuleNotFoundError: No module named 'grgsm'

This is bash_profile

 GNU nano 4.5                                                                                      .bash_profile                                                                                       Modified  
export PYTHONPATH=/usr/local/lib/python3/dist-packages/:$PYTHONPATH

If i type "echo $PYTHONPATH" terminal, this shows up on terminal

echo $PYTHONPATH

Hi @kiransgk1si18lvs04,

grgsm_scanner works on command terminal in kali linux, but not works on above program.

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

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

[velichkov]

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

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.

Thanks for your time and help velichkov

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

Hi @kiransgk1si18lvs04,

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.

Greetings, Dear friends pls advise me how to settle my issue,

After i call: gnuradio-companion grgsm_livemon.grc it opens fine and have few blocks in red (gsm_input etc.)

System infos: Operating System: Kali GNU/Linux Rolling Kernel: Linux 5.5.0-kali2-amd64 Architecture: x86-64
