Hi, Before I installed Gnuradio from the binary package it works well.
In  Ubuntu 20.04  when I want to build Gnuradio from source, it not works...
Terminal, I received the following message:

*Cannot import gnuradio.*

*Is the python path environment variable set correctly?

*


   - All OS: PYTHONPATH*
      -
      -

*Is the library path environment variable set correctly?*


   - Linux: LD_LIBRARY_PATH*
      - Windows: PATH*
      - MacOSX: DYLD_LIBRARY_PATH*

*I had set the path in .bashrc*

export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/dist-packages
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

*I had ldconfig after making Gnuradio Source*

I saw all links but my problem is not solved.

thanks in advance
