Undefined symbol: _Z20gr_make_io_signatureiii

GNU Radio

Hey!

I installed gnuradio like described here:
http://gnuradio.org/trac/wiki/UbuntuInstall and everything worked fine.
Now I try to run the benchmark and i get this:

sudo ./usrp_fft.py
Traceback (most recent call last):
File “./usrp_fft.py”, line 23, in
from gnuradio import gr, gru
File “/usr/local/lib/python2.5/site-packages/gnuradio/gr/init.py”,
line 27, in
from gnuradio_swig_python import *

ImportError:
/usr/local/lib/python2.5/site-packages/gnuradio/gr/_gnuradio_swig_py_runtime.so:
undefined symbol: _Z20gr_make_io_signatureiii

I tried to find answers in the history here but was not successful, can
anybody give me a hint? I get the same error with usrp_benchmark_usb.py

thanks!

Did you install the binary packages or did you compile from source,
and if so, did you you download a release tarball or check out the
source code using Subversion?

ImportError: /usr/local/lib/python2.5/site-packages/gnuradio/gr/_gnuradio_swig_py_runtime.so:

Could you please try:

$ sudo ldconfig

And re-test?
