Onderwerp: Re: [Discuss-gnuradio] Executing the flow graph: window closes immediatly
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?
Best regards,

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

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
