Re: Minimal deployment of gnuradio application.
Thanks alot for your input guys! I will take a look at the application. It might be of some use for me going forward!

Minimal deployment of gnuradio application.
Hi guys! Let me start by saying that I am pretty much clueless when it comes to building and linking so I am sorry if what I am asking is unclear or not relevant to this forum. But I'm going to give it a shot. I am working with a gunradio application containing my own OOT-module. The application is intended to run on diskless netbooted clients. The target OS is Ubuntu 18.04 LTS and Gnuradio version is 3.7. Do you guys know if it is possible to easily build my application with statically linked gnuradio and oot libraries so that I can deploy only binaries and library files to the clients without the need to have a full gnuradio installation on them? In short I want to have a working minimal executable with as few and small files to be deployed as possible. I appreciate any insights. Regards, Victor

message passing issue in systemd context
Hi.
I am having issues running gnuradio flowgraphs containg message passing in
a systemd context.
I have tried running a minimal flowgraph only containing a message strobe
and a message debug block.
When I run it manually it works just fine, but when executed from a systemd
service the flowgraph restarts all the time.
Here is some cutouts from journalctl:

I an running Gnuradio 3.7.13.4 on Ubuntu 18.04.1 LTS
I have attached the flowgraph, systemd unit file and the /etc/environment
setup file.
Thank you for any assistance!
