Re: New package required to build freedv modules in 4.5.0

Hi,

"-DCODEC2_DIR=/opt/install/codec2" is missing in the final step to compile SDRangel. This has been fixed in the Wiki

Hi Alain,

normally you should be able to fork and make PRs that's what all people do. Anyway this part is still very much under construction and is far from being in a workable stage and is going to be refactored heavily. Thanks for the tips indeed the last RUN commands have no effect when you start again the container.

I see you aim at a headless variant but sdrangel is the GUI variant and requires an X display with OpenGL. However the server variant must be also built as /opt/install/sdrangel/bin/sdrangelsrv.

Brgds, Edouard. 
Re: Dockerized sdrangel

alain@...
 

Edouard,

Thank you for the clarification.

I see you are trying to run those daemons via "RUN", which is incorrect.
I tried pushing a branch for a pull request but I have no permission to do that. In any event, at the end of the Dockerfile you should use something like this:

 

# Start some services on which SDRangel depends
COPY start.sh /start.sh
ENTRYPOINT ["/start.sh"]

and then add the start.sh executable in the same directory (make sure it is executable):

 

#!/bin/bash
sudo service ssh start
sudo service dbus start
sudo service avahi-daemon start
/opt/install/sdrangel/bin/sdrangel

Unfortunately, those modifications solve the first problem but reveal another one:

Is the segmentation fault related to OpenGL? I can't tell.
It would really be nice being able to have this running in Docker, at least for the headless client.
Re: Dockerized sdrangel

Edouard Griffiths
 

Hi,

Running in docker is not officially supported yet, I don't think you will ever see it mentioned anywhere yet. However I am exploring this and currently having a hard time with NVidia OpenGL on a Linux host. Actually this seems easier in Windows with Xming. Compilation should run smoothly though. At the end you should add:

RUN sudo service dbus start \
&& sudo service avahi-daemon start

The idea is to have a pretty much fail safe build from source in any environment getting rid of all the hassle and issues with package builds.

Contributions welcome...

Brgds,
Edouard.

Yes, It is a mac :)

I have no devices attached to this laptop as my plan are to use run sdrangel headless. Am I doing anything wrong?
Thanks for your help.

Re: New package required to build freedv modules in 4.5.0

James Dallas
 

Eduoard,

I interpreted it as, "you will need to build yourself."

What is unclear is what version of codec2 is needed.

I have tried with both 0.7 and 0.8 and doesn't seem to work.

Will try the development branch, but it looks like I'll need to figure out how to build that with speex.

Re: New package required to build freedv modules in 4.5.0

Yes, I see that make tried to build the FreeDV modules after I downloaded libcodec2-dev, but failed because of some changes.

I am going to try to see if I can build latest codec2 and see if that works.

New package required to build freedv modules in 4.5.0

James Dallas
 

Hi everyone,

I didn't find it obvious in the release announcement, but since this version is only available to those building from source, you will need to install the codec2 package before building 4.5.0 on Linux to take advantage of freedv.

I tried building without it and it build, but freedv didn't show up, either in the GUI or as a compiled .so file. After going and looking at the cmakelist file, I realized that codec2 was needed.

So I did "sudo apt-get install codec2" then rebuilt. And that didn't work either.

I'm trying again after installing libcodec2-dev. I suppose I could also try building latest codec2 from source (the Ubuntu 18 repos use .07-1).

Anybody else have success, and if so, with what steps?

Hi,

I think this sort of thing was put in place for HackRF. However in the meantime the REST API was developed and is now the preferred way of managing the application with an external agent. This is typically the case where you would have a Python (typically) script running in the background that listens for changes in frequency on one sife and copies it over to the other side. This would aldo support heterogeneous Rx/Tx combinations. I'll try to post a gist or example in the examples directory to demonstrate this.

Re: Install from binary v source, missing swagger

Mick
 
Edited

Edouard,

Thanks for the very fast response. I will create a /opt/build folder and move them into the correct place as if I had built from source.

It might be worth adding that info to the binary releases wiki, it had me stumped for a bit but it wasn't a major drama. it just made me question if there were any other differences in the builds.

Thanks again for the quick response. The software is fantastic and with the availability of LimeSDR Mini and the recent arrival of the Amateur transponders on Es'hail-2 at 26E, I am sure the downloads server will be seeing plenty of traffic at the moment.

Re: Install from binary v source, missing swagger

Hello,

at the moment the API client examples are not deployed anywhere. They are not essential to the working of the binary and completely standalone. I may think of deploying in a subfolder of the share directory for completeness.

Install from binary v source, missing swagger

Mick
 

Hi,

Just checking I havent missed something, installed from binary on Mint 19 and everything is working.

I have just tried command ptt and had to download the source from git as the /build/swagger/examples are not included in the binary install. I assume I am not missing anything else and that I can move stuff around into the /opt directory or link to the downloaded sdrangel source folder .

If I am missing something else crucial I might compile from source, but everything else seems to be there.

Has anybody else, found anything else, missing from the binary version compared to compiling from source?

I already have LimeSuite and Soapy installed and the LimeSDR mini is recognised by the binary install.

Cheers

Thank you Eduoard. I believe we had a similar discussion some months ago. So I can confirm you've been firm and consistent on this point. =D

FWIW here are some random thoughts for the group that I've had along these lines (TX/RX switching and such):

(1) There is a Linux program called statserial that you can use to monitor the status of a serial line (either real or virtual). A lot of software programs for digital ham modes (WSJTX, FLDIGI, etc) allow you to control rig PTT using a serial port line. Using statserial you could monitor the status of, say, the CTS line and use changes there to trigger a curl call to the sdrangel REST API, or trigger a relay using usbrelay (as linked to in my previous e-mail). Or both. At any rate, statserial can be used to build a bridge between "old school" (pre-SDR) ham radio software and sdrangel.

Example output on my Linux VM at work (I came up with this while taking a short stress break before serving patching last week):

(2) I wasn't aware of the reverse API, but this makes a lot of sense and I'll have to play around with that. Would definitely be better than having to loop / constantly poll the API to get the PTT status.

Think of it as a modern software oriented CAT interface. You wouldn't ask Yaesu or Icom to implement support for this or that GPIO board in their rigs firmware. This is a similar case here transposed to the software realm. So anything that you would like to support like PTT or filter switch-boxes has to be done through a custom DIY application that interfaces with SDRangel using its REST API. 
 
I have indeed enough work with maintenance and trying to develop new signal processing oriented features.
