Re: [Discuss-gnuradio] Trouble with gnuradio-companion after pybombs installation

[Kyeong Su Shin]

Hello Pavan Yedavalli:

I don't use PyBOMBS so maybe I am wrong, but that sounds like that path variables (for bash) are not correctly updated to include the path to the GNU Radio libraries OR you have already installed an another version of GNU Radio (using manual build or apt-get) and is conflicting with your PyBomBs installations. 

A few things to check:

1.Did you make sure that your computer does not have an older version of GNU Radio?

2.Did you try pybombs run gnuradio-companion instead?

3.Did you try printing out path variables (PYTHONPATH, PATH, LD_LIBRARY_PATH, C_INCLUDE_PATH, CPLUS_INCLUDE_PATH ) after running "source ~/prefix/setup_env.sh"? Does it look correct? (Note: you have to run "source ~/prefix/setup_env.sh" every time you open your terminal.)

If you don't want to build it using PyBOMBS, you can just install one that is on the official Ubuntu repo (sudo apt-get install gnuradio-dev). The one that comes with Ubuntu 14.04 is pretty outdated, though. (Maybe you can dist-upgrade to Ubuntu 16.04 or later, which comes with a more recent vintage of GNU Radio). 

Alternatively, you can do a full manual build by downloading dependencies and do a full manual build following instructions at https://github.com/gnuradio/gnuradio . Note that this can be a somewhat annoying process, and that is what PyBOMBS is attempting to solve. (Somewhat outdated list of dependencies: https://wiki.gnuradio.org/index.php/UbuntuInstall . Also, please note that you may have to do "git clone --recursive https://github.com/gnuradio/gnuradio.git" instead of "git clone https://github.com/gnuradio/gnuradio.git" since the latter command may not clone source codes for Volks.)

Finally, you can simply use GNU Radio live image.

Hi,

I successfully followed the instructions on github to install pybombs, cloning the directory and then running

sudo python setup.py install

Everything successfully finished:

address@hidden:~/pybombs$ source ~/prefix/setup_env.sh

But then when I run gnuradio-companion, it gives me the following error:

address@hidden:~/pybombs$ gnuradio-companion
Traceback (most recent call last):
  File "/home/pavan/prefix/bin/gnuradio-companion", line 99, in <module>
    run_main()
  File "/home/pavan/prefix/bin/gnuradio-companion", line 87, in run_main
    from gnuradio.grc.main import main
ImportError: No module named main

Why is it not able to find the "main" module? It seemed like everything was installed correctly. I did this install multiple times after removing the pybombs directory and doing it again, but it continues to give this same error. I don't really know where to go from here.

I saw that Mike Willis had a similar problem a bit ago and he said he found random files in 

/usr/lib/python2.7/dist-packages/gnuradio/

Is there a way I can clean up/uninstall everything and just start from scratch with the correct steps also (I'm using Ubuntu 14.04)? I was hoping that all the steps in the pybombs installation would make everything work correctly. Please let me know.
Thanks so much for the help.
