Hi Marcus,

I've gotten a surprising thing and I couldn't explain why.

First, I type: sudo gnuradio-companion to open the GNUradio and test my own module. It turned out an error message as I described in the previous mail. (ImportError: No module named Tool_NetworkCoding)

However, when I just type: gnuradio-companion and also run the same grc file, the error message disappeared, and everything then seems to go well.

So, is there any difference between sudo gnuradio-companion and gnuradio-companion ?

Thank you very much

Van-Ly

Yes. Using sudo, you're running as root with root's environment that usually doesn't know about things in /usr/local (PATH, PYTHONPATH, LD_LIBRARY_PATH, etc.). You should not be running gnuradio-companion as root, anyways. No need to sudo everything!

Hi Van-Ly,

if you installed everything correctly, Python should be able to find the module.
You can verify this by looking at the install_manifest.txt in your OOT's build/ directory, in which there should be an entry for every file it copied.
Find your python files (there always should be an __init__.py) and check if the target location is part of your $PYTHONPATH.

Greetings,
Marcus

Hi all,

I have created a new module called Tool_NetworkCoding. During the
installation, I did not get any error message, everything went well. But
when I run a grc file to test some blocks inside this new module, it turned
out an error message:



*Traceback (most recent call last):  File
"/home/van-ly/Downloads/top_block.py", line 16, in <module>    import
Tool_NetworkCodingImportError: No module named Tool_NetworkCoding*

Please help me with this.
Thank you in advance
Van-Ly
