Why Can't PyCharm Find My Installed GNU Radio Package?

Importing Installed Packages in PyCharm

Despite adding the correct environment and ensuring GNU Radio functions outside of PyCharm, you may encounter an "undefined reference" error when attempting to import it within PyCharm. One common solution lies in configuring PyCharm's paths.

Path Configuration

1. Navigate to File → Settings → Project Settings → Project Interpreter.
2. Click "configure interpreter" and select the "Paths" tab.
3. Press the " " button and specify the path to the module you wish to import (e.g., /usr/local/lib/python2.7/site-packages/gnuradio).

Locating the Path

If unsure of the path, open the Python interpreter and import the module:

>> import gnuradio
>> gnuradio.__file__
"path/to/gnuradio"

Typically, the folder structure will be organized as follows:

foobarbaz/
  gnuradio/
    __init__.py
    other_file.py

In this case, you would add "foobarbaz" to the paths in PyCharm. By configuring the paths appropriately, you can ensure that PyCharm recognizes installed packages and allows for their seamless import.
