Using uhd_fft with USRP N210

GNU Radio
1

Hi,

I,m trying to run uhd_fft with USRP N210, my machine run Ubuntu 12.04.4
LTS. I’ve already install UHD, gnuradio, & OpenBTS in my machine & works
fine.

But when i try to run uhd_fft which is in
/var/opt/gnuradio-3.7.0/gr-uhd/apps directory, i’ve got the following
message:
root@OpenBTS:/var/opt/gnuradio-3.7.0/gr-uhd/apps# ./uhd_fft
Traceback (most recent call last):
File “./uhd_fft”, line 23, in
from gnuradio import gr, gru
ImportError: No module named gnuradio

I’ve already try to run make & make install command in
/var/opt/gnuradio-3.7.0/build/gr-uhd directory, as suggested in previous
discussion, but it still show the same result.

Can anyone help to solve this issue.

Thanks,
Tides

I’m going to guess that it’s because your PYTHONPATH doesn’t point at
wherever your installer put the various Python modules that Gnu Radio
needs. It’s really weird to install permanent libraries and
executables under /var/opt.

Any suggestions or reference maybe? where should i install the install
permanent libraries and executables?

Thanks

Well, /usr/local is the most usual place for Ubuntu. Sometimes under
/opt.
