Hi Cédric, Results of dpkg queries are given below. It looks like those files are not part of any installed packages:
$ dpkg -S "libuhd.so.003.010.003" --> dpkg-query: no path found matching pattern *libuhd.so.003.010.003* $ dpkg -S "$(basename "/usr/lib/x86_64-linux-gnu/libuhd.so.003.010.003")" --> dpkg-query: no path found matching pattern *libuhd.so.003.010.003* $ dpkg -S "libuhd.so.3.15.0" --> dpkg-query: no path found matching pattern *libuhd.so.3.15.0* $ dpkg -S "$(basename "/usr/lib/x86_64-linux-gnu/libuhd.so.3.15.0")" --> dpkg-query: no path found matching pattern *libuhd.so.3.15.0* What I find interesting is that when I run "gnuradio-companion" from the terminal, it attempts to load my 2 most recent flowgraphs "save_rx_samples_to_file.grc" and "spectrum_analyser_two_chan.grc", even though I have never opened them in this version of gnuradio-companion. This suggests that the built-from-source installation has been polluted by a config file or history file from the Ubuntu Software version of GRC that I installed over the top of the built-from-source version. I think I will try and scrub my system of everything related to GNU Radio this morning, and reinstall it from source one more time. If it still doesn't work, I will take it up with the GNU Radio mailing list...........or possibly switch to Matlab!! :) Thanks & Regards, Brendan.
