stdcdec's Issues

(Question/Help) Receiver and Demod setup

I’ve previously been successful in receiving data using a wine appimage and scytale-c at least as far as the demod piece and data getting over to the UI - however due to a think sql and wine issues the actual messages were not parsed/displayed.

It appears with this project I can replace all of that. I just maybe need a little better understanding of the low/high/center freq settings and if that somehow correlates to what I have set in gqrx. You’ll see in this picture I’m using SDR++, but I was also using gqrx and sending over udp to your application. I’ve just gotten started so I’m sure I’m not doing something right, so far I’ve not seen any indication of information being passed between windows. Any help with initial setup would be much appreciated.

inmarsatc_parser.h location

New to the project, but while building I'm getting a failure with make do to the missing parser header. Is that something I have to find elsewhere or part of some other package?

Dependencies to Document

Just mentioning so the README can be updated (or someone can find this if they run into trouble compiling) - on Raspbian/RaspiOS you need to install two dependencies for this to compile:

apt install libaudiofile-dev libasound2-dev

Cannot compile on Artix/Arch Linux

I'm using Artix Linux, all packages up to date, and compilation fails with this error:
