Hi Nate,

Not really. I added line to .profile (that's where I maintain PATH) and reexported PATH with the new value, b4 starting the companion. It shouldn't make a difference.

I then rebooted my PC, just to make sure that PATH was updated correctly, same error as before.

BR,

If you just try to execute the generated .py file, from a window that apparently has correct PATH, what happens?

Hi Nikos,

Did you restart gnuradio-companion from a new terminal after adding the line to your ~/.bashrc file?
