Re: [Discuss-gnuradio] GNU Radio Companion missing source

[GeorgeF]

Thanks Mike for the suggestion.

I put together a fresh Ubuntu system, installed git, cmail, libusb-1.0-0-dev and build-essential as well as openssh-server.  So nothing else to get in the way.

I think did the pybombs.  It appeared to all compile and link fine.  Took a bit over 2 hours (semi-slow machine).

Now when I type "gnuradio-companion" I get a message saying gnuradio-companion not installed, it suggests I do the sudo apt-get install gnuradio.

I thought by doing the pybombs that was all to be included?  what am I missing now?

Thanks
George

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

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.

The gnuradio package doesn't contain every GNU Radio module that exists ;)
you still need to install gr-osmosdr and libhackrf; see my last mail[1].
