Again! no module named grc!

GNU Radio

Hello G.s,

How can I debug the problem when I type grc in the terminal, I get:

File “/usr/local/bin/grc/”, line 33, in
from gnuradio.grc import VERSION
ImportError: No module named grc

I got the dial_tone.py working so I do not think it is a python path
problem but I am not sure, also when I run usrp_probe, I get:
Traceback (most recent call last):
File “/usr/local/bin/usrp_probe” , line 28 , in
from gnuradio.grc.gui.Dialogs import TextDisplay
ImportError: No module named grc.gui.Dialogs

Please advise.

Kind regards,
Yahia Tachwali

I know that this problem have been repeated alot in tis maillist but for
me, non of the export statements for python or boost libarary helped in
solving the problem. Indeed, I had this working before but after a
restart this problem showed up again and I am really confused what
should I do.

Kind regards,
Yahia Tachwali

Hello Josh,

Thanks alot for your help. Noting that this problem appeared after the
restart, it turns out that the Pythonpath was altered to a default
value. I have a 64bit machine so the libraries are in lib64 folder and
not lib as defaulted somehow in my pc when I do the restart. I followed
your instruction that includes setting up the right values for the
pythonpath and it worked.

To avoid the problem to appear again , I had to add this export
statement in the .bashsc file.

Thank you very much for your help.

Kind regards,
Yahia Tachwali

Step 1) Lets avoid issues with multiple versions of gnuradio and stuff
like that. Remove all gnuradio stuff in /usr with rm -rf. Dont let a
single gnuradio directory survive.

Step 2) Run sudo make install from your gnuradio build directory. Take
note where the python files get installed.

Step 3) run this in the terminal:

python -c “from gnuradio import grc”

If there is no error, then grc and gnuradio should work. Done!

However, if this program spits out an error, you must set your
PYTHONPATH. The python path is a directory that ends in site-package or
dist-packages. Mine is /usr/local/lib/python2.6/dist-packages

Step 4) Set your python path by adding this line to ~/.bashrc

export PYTHONPATH=/your/pythonpath/here

Step 5) type bash, then run this command again:

python -c “from gnuradio import grc”

it should work!
