GNU Radio Companion missing source

addis_a · August 24, 2014, 5:00pm

I just installed GNU on a Ubuntu 14.04 LTS machine.

Here is how I installed it: “sudo apt-get install gnuradio” All
appeared good, I thing typed “gnuradio-companion” and got the it up and
running.

Problem: On the right side of the display I am missing a few things, 1
of which is SOURCE. (SINK also is mission).

What did I do wrong?

Thanks
George

Hello George,

two things:

generally, ubuntu packages of GNU Radio become outdated, and it’s
preferable to install things yourself, e.g. from source using pybombs;
but for now, you’re likely to have GNU Radio 3.7.2, which is modern
“enough”, though it’s missing a few cool features that have been
introduced up to now (3.7.4).
there is not a single “SINK” or “SOURCE” block; these are only
roles a block may play in a flowgraph, ie. a source is a block that
has only outputs, and a sink has only inputs; what exactly are you
referring to?

Greetings,
Marcus

Also, your host is telling me that it’s blocking my mail server’s IP

Ironically, it responds with "host nb-mx-vip3.prodigy.net[207.115.36.22]

Hi George,

in that case, you’ll have to install gr-osmosdr [1].
To use your hackRF, you’ll also need libhackrf [err… google.].
you can now take the following routes:

a) install gnuradio-dev from ubuntu,
download, build and install libhackrf (installing all tools and
development libraries necessary yourself),
then download, build and install gr-osmosdr against the Ubuntu GNU
Radio package

or

b) uninstall Ubuntu’s gnuradio package (!), download pyBOMBS[2], and
doing
./pybombs install gr-osmosdr
which should automagically download, build (if no suitable binary
package is available) and install all the necessary components.

Greetings,
Marcus

I am trying to find the osmocom and/or RTL-SDR sources.

I’m running GNU Radio Companion 3.7.2.1

In GNC I did a search for osmocom and RTL-SDR and nothing was found.

What didn’t I setup correctly during the “sudo apt-get install gnuradio”
install?

Thanks
George

Thanks for the response.

I was watching a video by HackRF on how to get started with GNU. In
order to build a simple FM receiver, the first block he selected was
“osmocom Source” found under the block labled “[Sources]”.

That is what I’m looking for…

Thanks

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].

Just as the GCC C compiler doesn’t include every program that has ever
been written with it, nor every library that has ever been written with
it, so too, the “gnuradio” package only includes the core Gnu Radio
functionality. Just as other packages have “plug-ins”, Gnu Radio
organizes many of its “extra stuff” similarly.

You’ll need to install “gr-osmosdr” along with “hackrf” and
“libhackrf-dev”

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.

GeorgeF · August 26, 2014, 10:20am

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

Yes, this can happen with other packages as well (gr-osmosdr, for
example) if you are running this module as built against a different GR
version than you have installed.

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

GeorgeF · August 27, 2014, 1:46am

Ok I am getting much farther along.

I did the “./pybombs env” command. Then it told me to run: “source
/home/av8tor/target/setup_env.sh” which I did. Once I did that I could
run gnuradio-companion and it started just fine.

However I’m still at a loss as to what I need to run in order to get
[Sources] block to appear in order to choose either osmocom Source or
RTL-SDR Source.

To recap, in order to get to this point I did the following on my Ubuntu
computer:
./pybombs install uhd gnuradio hackrf
./pybombs env
source /home/av8tor/target/setup_env.sh

What else do I need and how do I install it.

Its been many many years since I’ve programmed on Unix, and done very
little so far no Linux.

Thanks for everyone’s patience.
George

GeorgeF · August 27, 2014, 7:58am

./pybombs install uhd gnuradio hackrf
./pybombs env

What else do I need and how do I install it.

./pybombs install gr-osmosdr

Cheers,

Sylvain

GeorgeF · August 26, 2014, 9:03pm

Maybe you’ve installed it into a prefix?
you can run “pybombs env” to get a file that you can use to set up
your paths correctly

I’m unable to solve the segmentation fault issue.
I install gnuradio from the script. When i run gnuradio-companion, I
get:

Then it suddenly crashed when I use any of the osmocom blocks and says
