Re: [Discuss-gnuradio] Evaluation failure of oot module block

[Michael Dickens]

Hi chandan - Try setting the PYTHONPATH environment variable in your
shell to include the /path/to/your/module, and make sure that the
/path/to/FEC/module is also in the PYTHONPATH, if they were installed
into different directories. All of the GR modules need to be in the
PYTHONPATH somewhere in order for the to be found and work correctly.
Hope this helps! - MLD
