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!

I have just upgraded to Ubuntu 8.10 on my 64-bit machine (a few weeks ago). Did you do this? (which is on the wiki): Because Debian and Ubuntu apply a poorly implemented "enhancement" to the upstream version of libtool, they break the ability to test code and libraries prior to installing them. We think that testing before installation is a good idea. To work around their damage, be sure to include $PREFIX/lib (and $PREFIX/lib64 on 64-bit machines) in /etc/ld.so.conf. If you don't include $PREFIX/lib in /etc/ld.so.conf, you will see errors during the linking phase of the build. There are several places it shows up. The first one is often during the build of mblocks. It's not an mblock problem. It's a Debian/Ubuntu problem. Do this to work around the "feature": cp /etc/ld.so.conf /tmp/ld.so.conf echo /usr/local/lib >> /tmp/ld.so.conf sudo mv /tmp/ld.so.conf /etc/ld.so.conf sudo ldconfig -- Newell http://www.gempillar.com Before enlightenment: chop wood, carry water After enlightenment: code, build circuits
