Can there be better installation instructions?

[leecollings]

Hello,

I've come here after failing to be able to install pagermon (because of terminal errors and that package installation steps not exactly being helpful), and I've found these installation steps are equally not as helpful.

Can you adapt them to make it clear how to get this up and running from a new system install? For example, you referencing using qmake or cmake (but then give no instruction on how to install these)...

When I run a qmake command, I get the following:

qmake: could not exec '/usr/lib/qt5/bin/qmake': No such file or directory

So some better installation instructions would be really helpful. So far, using a Raspberry Pi 4, it seems absolutely impossible to be able to decode POGSAC messages on this (as every online tutorial or project I've tried simply doesn't work, with little installation support).

Any help is greatly appreciated.

Eventually I managed to install cmake, and then ran through the installation instructions, but there are errors and warnings coming back after installing:

Now it seems installation has completed, but now what? The installation instructions stop here, and there's nothing else I can see in the readme that explains how to actually use this.

Is there a GUI I need to open? I'm using GQRX to scan and listen to frequencies, but how I can then process that into multimon-ng to be able to decode POGSAC messages?

Can you please update your readme to make this much clearer? Thank you!

Hi,

While it would be nice to have more information in the README, there are a few things that I could recommend for you.

I don't know what level of knowledge you have running Linux, and the first thing I would recommend is to run the command "man man", without quotes. Read through that manual (man) page, and then when you are comfortable with that information, move on to the next paragraph.

With the knowledge of what man is, and how to use it, and the output you pasted from the installation commands (it's a good idea to read through all of that), the last 2 lines in the output you pasted are telling you exactly what was installed, and where it was installed. The penultimate line is telling you that a man page was installed at "/usr/local/share/man/man1/multimon-ng.1". Using man you could read how to use what you have installed by typing "man multimon-ng", and hitting enter, and reading through that man page.
