I recently had the same 'segmentation fault' error which was due to having 'gr-baz' installed. See this post for info on debugging the segmentation fault:
http://lists.gnu.org/archive/html/discuss-gnuradio/2013-11/msg00232.html Essentially, run the following: gbd --args python $(which gnuradio-companion) run #wait for crash bt Look at the top of the output for a gr module that looks suspicious, in my case uninstalling gr-baz fixed the issue. I'd highly recommend using the pybombs technique to install GNU Radio as a non-root user. It also allows you to install and uninstall GNU Radio and lots of other stuff as simply as running the following: ./pybombs install uhd gnuradio hackrf The url for the pybombs wiki is here: http://gnuradio.org/redmine/projects/pybombs/wiki If you choose this route, make sure you uninstall everything related to uhd/gnuradio/hackrf/osmosdr etc by manually going into each project's 'build' folder and typing: sudo make uninstall ...and then run a final check by searching for anything related to uhd/gnuradio.hackrf/osmosdr etc by running the following: sudo find / -name gnuradio Mike -- Mike Jameson M0MIK BSc MIET Email: m...@scanoo.com Web: http://scanoo.com On Mon, Aug 25, 2014 at 9:23 PM, Marcus Müller <marcus.muel...@ettus.com> wrote: > The ctrlport related warnings are ok (they are but warnings), the > segfault is bad; as you might imagine, it's not the easiest thing to debug. > However, I really hope you uninstalled Ubuntu's gnuradio package first, > before using build-gnuradio? > Also, you'll *still* have to install libhackrf and gr-osmosdr to get the > sources you were missing in the first place. > > Greetings, > Marcus > > > On 25.08.2014 21:55, GeorgeF wrote: > > One thing I tried was "wget http://www.sbrac.org/files/build-gnuradio > && chmod a+x ./build-gnuradio && ./build-gnuradio" > > > > After almost 4 hours it completed.
