[Discuss-gnuradio] Installation problem on 64-bit ubuntu intrepid

[Songpvamu Gao]

Hi,

My system info:

uname -a
Linux user 2.6.27-9-generic #1 SMP Thu Nov 20 22:15:32 UTC 2008 x86_64 GNU/Linux

I have been using gnuradio/usrp on 32 bit ubuntu for a while, never have problem with installation. Yesterday, I decided to switch to 64 bit ubuntu and install gnuradio follow the procedure what I did on 32 bit system. Installation is smooth, and I can find usrp by 
ls -lR /dev/bus/usb | grep usrp

But when I try to run /usrp_benchmark_usb.py, I got the following error message

  File "usrp_benchmark_usb.py", line 30, in <module>
    from gnuradio import gr
  File "/usr/local/lib/python2.5/site-packages/gnuradio/gr/__init__.py", line 43, in <module>
    from gnuradio_swig_python import *

  File "/usr/local/lib/python2.5/site-packages/gnuradio/gr/gnuradio_swig_python.py", line 23, in <module>
    from gnuradio_swig_py_runtime import *
  File "/usr/local/lib/python2.5/site-packages/gnuradio/gr/gnuradio_swig_py_runtime.py", line 6, in <module>

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

Seems like library libgnuradio-core.so.0 is missing, but I can loate the library in /usr/local/lib/libgnuradio-core.so.0.

Anyone has an idea how to fix the problem? Thanks a lot!
