Dear List,

i tried to decode airprobe sample file with the following line:

./go_usrp2.sh vf_call6_a725_d174_g5_Kc1EF00BAB3BAC7002.cfile 174 0B > vf_call6

but only got the following error message:

***@ZevenOS:~/airprobe/gsm-receiver/src/python$ ./go_usrp2.sh
vf_call6_a725_d174_g5_Kc1EF00BAB3BAC7002.cfile 174 0B > vf_call6
Traceback (most recent call last):

ImportError: libgnuradio-core-3.5.1git.so.0: cannot open shared object file: No
such file or directory



compiling and installing gnuradio and python worked fine.
libgnuradio-core-3.5.1git.so.0 is as a link to
/usr/local/lib/libgnuradio-core-3.5.1git.so.0.0.0 at /usr/local/lib

maybe some one could help me ?
btw: i got no usrp, just want to try out the samples...

Thank you!

Suggest ask on the gnuradio mailing list, since gnuradio somehow
can't find the needed library.

Quick tip would be to verify that /usr/local/lib is mentioned in
/etc/ld.so.conf and then run ldconfig once as root.

If that doesn't help then I think your install is somehow broken.

Also don't forget to take a look at your python path, mine is like that:

$ env | grep -i python
PYTHONPATH=/usr/local/lib/site-package

(export PYTHONPATH=/usr/local/lib/site-package)
