Hi Nick,
I'd personally say that the GNU Radio packages in Ubuntu should be
pretty up to date (thanks, Maitland!), but the UHD in Ubuntu is
extremely old, so if you want to use USRPs, you can't use Ubuntu's
GNU Radio.
Since building isn't that hard nowadays, and you had bad experiences
with the Ubuntu package, I'd just try using pybombs [1]:
git clone --recursive https://github.com/pybombs/pybombs.git && cd pybombs && ./pybombs install gnuradio
You should be able to answer all questions with the default (just
<enter> your way through the dialog), then after everything is
complete:
./pybombs env
and add the generated file to your bashrc:
echo "source <path that was used as prefix>/setup_env.sh"
>> ~/.bashrc
Open up a new terminal and run gnuradio-companion.
Best regards,
Marcus

Hi Marcus,
I'm sorry i made just a terrible mistake: i reply'd to the
wrong tread.
This was my answer:
Marcus,
I
just saw i was still running a 32 bit installation of linux.
I just removed my old installation and busy reinstalling a
fresh Ubuntu 14.04 LTS.
What
instalation way is best? Installing by the sudo apt-get
install command or just build my own version?
best
regards,
Nick

Hi Nick,
I don't know whether this is good or bad news: On my machine,
this runs beautifully.
I don't have Ubuntu 14.04 LTS at hand, but since that is one
of the main platforms that people use to work with GNU Radio,
a systematic error in GNU Radio would most likely have been
spotted already.
Now, I'd like to ask you to run the flowgraph with GDB, to get
more debugging info. Is that alright with you?
sudo apt-get install gdb #if you don't have gdb installed
gdb python /path/to/flowgraph.py #path is displayed in the GRC
console when you hit the "generate" button.
(gdb) run
Best regards,
Marcus
In attachment is the .grc file.
Best regards,
Nick

That does sound correct; so we need to really look
deeper into what goes wrong in your flowgraph. Which one
from that tutorial are we talking about specifically?
Can you share the .grc file?

Marcus
Hi Marcus,
I installed the gnu radio from the command
"sudo apt-get install gnuradio" trough the
terminal.
This installation went smooth and I did not
observe any problems.
Best regards,
Nick

Executing the flow graph: window closes immediatly
Hi Nick,
segmentation fault is a severe error; it means
that the program you generated tried to access
memory that wasn't there. The error really doesn't
say anything more.
We haven't seen such error in released GNU Radio
versions lately.
My guess therefore is that there might be
something wrong with your set up instead.
How did you install GNU Radio? If you've installed
it from source, or build-gnuradio, or pybombs you
*must not* install gnuradio from Ubuntu's package
archives.
Best regards,
Marcus
Hello,
I'm totally new to the gnu radio project
and trying my first steps into the world of
SDR.
I made the flowchart exactly as described
in the tutorial, but when i try to execute
the flow graph, a window appears and
directly closes.
When I try to run the code directly from
the terminal i get following message:
Segmentation fault (core dumped)
I'm running Ubuntu 14.04 LTS.
How can I fix this issue?
Regards
Nick
