I haev made many, and you do not say what you did, or the results, so
nothing anyone can do with that statement.

Nope.  Does not matter what your cwd is.  To start gpsd you should
be root.  The clients can run as any user, in any directory.

Assuming you followed the buildinstructions.  Which you still have not
confirmed either.

If you can't get it to run without systemd(umb), you;ll never figure out
to run it with systemd(umber).  Just be sure systemd(umbest) is
not controlling gpsd.

cgps is NOT a python program!  It is a C program, that you built and
installed using the procedure in build.adoc.

You only need to do it once.  You already did it.

First, be sure you installed all of gpsd, per build.adoc

second, gpsd must be running:  gpsd -n /dev/ttyACM0

Third, as any user, in any directory type in the shell: cgps
