Forum: GNU Radio AttributeError: 'module' object has no attribute 'square_ff'.

hi everyone,i have made my own block in gnuradio name square_ff
from out of tree module.i hsvr successfully interfaced it
withgnuradio.but problem is when i want to use that block in gnuradio
then the following error i get in terminal.
AttributeError: 'module' object has no attribute 'square_ff'.
kindly help me

Someone can correct me if I'm wrong, but I think this is the error that
happens if you haven't run `ldconfig` (on Ubuntu).

Try `sudo ldconfig` There's a gnuradio wiki page that explains what it 
does
somewhere.
