Attempting to run /gnuradio-3.0.3/gnuradio-examples/python/usrp>
./usrp_oscope.py and I get:

Traceback (most recent call last):
File “./usrp_oscope.py”, line 25, in ?
from gnuradio import gr, gru

line 4, in ?

ImportError: libgnuradio-core.so.0: cannot open shared object file: No

What’s the solution?

Did you follow the Ubuntu install guide? Whenever I follow it, after
I’ve completely finished the guide I have to do a ‘sudo ldconfig’

Give it a shot.

I am not using Ubuntu.

What are you running?

Now it works.
This is a workaround, not a proper solution. The Right Thing would be to
configure /etc/ld.so.conf to include /usr/local/lib and run ldconfig as
root.

Your workaround depends on per-user configuration and is quite fragile.

Thanks for the assistance.

I am not using Ubuntu. Nonetheless, the problem is fixed.
I edited bashrc. ie:

towens@towens:~> vi .bashrc

Then I added the line to bashrc :
export LD_LIBRARY_PATH=/usr/local/lib

towens@towens:~> source .bashrc

Now it works.
