No module named rds_swig

[andrew-stclair]

when trying to run the example flowcharts, i get this error:

  File "/usr/local/lib/python2.7/dist-packages/rds/__init__.py", line 22, in <module>
    from rds_swig import *
ImportError: No module named rds_swig

when looking in that directory there are no files named rds_swig with any extension

i have tried compiling from your git repo and installing from the kali repo, neither fixed the issue

[andrew-stclair]

also happens when i try a custom flowchart

[andrew-stclair]

when reinstalling from apt, rds_swig.py exists but the error still occurs

Please don't use GNU Radio from distribution repositories. They are usually very outdated. GNU Radio officially recommends to use PyBombs for installation.

Can you check the configuration and compile logs if there is any warning about swig?

Apologies for the late reply, here is the execution log from gnuradio

and when run from terminal

i will try removing gnu radio and recompiling from its git repository and will let you know

[andrew-stclair]

using gnuradio from git fixed the issue

I had the same issue with GNU Radio 3.7.11 and python 2.7.14. Setting the following environment variables fixed the issue for me:

export PYTHONPATH=/usr/local/lib/python2.7/site-packages/
export LD_LIBRARY_PATH=/usr/local/lib

I have the same issues under Windows:

Trying more and more since weeks and found no solution...

Any recommendations that solve the problems under Windows environment ?

Thank you very much in advance and greetings from Ranstadt / Germany

[bastibl]

I don't use Windows, so I don't know about the common pitfalls there. But the problem is probably a linking error that hidden by Swig's Python boilerplate. Open C:\Program Files\GNURadio-3.7\gr-python27\rds_init_.py and print the errors that are thrown when trying to import rds_swig.

Hallo Basti, thank you very much for the quick reply. At the moment I´ve no time to try these tip - meanwhile I enjoy your great program whitout the RDS part. Without the RDS part: These parts of the program runs perfect and I think you have made a great job. I´m not fit programming python and if i have more time I ´ll try out what you adviced to me in the above mentioned post.

Have graet day

Peter
