Sort of.

Starts well.

The point is to save space, you should do it.

Dunno, you find that out later.

Good to here.  But then you skipped a number of steps.

Look here:

https://gpsd.io/building.html#_quick_start

Since you did the "git clone" you can ksip the tar extract, then do
the build and install.

Without all the steps you skipped, that can not work.  You can not run a
program you have not built yet, and not before you start gpsd.

You can't just skip the parts you don't understand.  Each step builds
on the preveddeing steps.


 In my case gpsd-X.YY is just

No.  You did a git clone, use that instead of the tar.

Just "cd gpsd"

Then that.  Then start gpsd, then run cgps.
