gnuradio-3.0.4 is working fine,even i have loaded the firmware on FPGA of the usrp.Its working allright.But when i try to run ./usrp_fft.py
from the directory
/home/jay/Desktop/GSM/gnuradio-3.0.4/gnuradio-examples/python/usrp/ i
get the following error:

Traceback (most recent call last):
File “./usrp_fft.py”, line 23, in ?

line 6, in ?

But however when i manually put the _gnuradio_swig_python.so in the
searching directory ,i get the follwoing error:
Import Error: cannot open libossaudio.so.0 from shared library.No such

First off, is there any reason you’re trying to install ancient GR code?
If not, please start with:

ftp://ftp.gnu.org/gnu/gnuradio/gnuradio-3.1.3.tar.gz

The read and follow these directions:

Hello Eric,
I have already tried installing gnuradio-3.1.3 but there were certain
bugs in that.So I had to go with gnuradio-3.0.2 and later upgraded to
3.0.4.Even the “Hello World” example is working fine,but when i try to
run any of the usrp examples i.e usrp_fft.py i get the error message of
“No module named _gnuradio_swig_python” .

I have _gnuradio_swig_python.la,_gnuradio_swig_python.so file only .If
i link with _gnuradio_swig.python.so I start getting error message of
“no libossaudio.so.0 file or directory”

Which _gnuradio_swig_python module should be linked inorder to remove
the error message.I am very badly stucked in this problem and also I am
very new to gnuradio.

So,kindly help me out.

Thanks

I definitely wouldn’t go back to anything before 3.1.3.

Are you sure you don’t have some partial GNU Radio installations
laying around? Did you try installing the old GNU Radio Debian
packages? If so remove them. I suggest removing all traces of GNU
Radio from your system, then starting over with a clean installation
of 3.1.3.

Not to belabor a point, but have you actually followed the
instructions in:

http://gnuradio.org/trac/wiki/BuildGuide
http://gnuradio.org/trac/wiki/UbuntuInstall

If you’re not on Ubuntu, see your distribution-specific instructions
linked off of the BuildGuide.
