Troubleshooting • gpsd with -G or --listenany does not bind to any address

Hi,

I have Bullseye on a pi zero w, stock Rasp bullseys updated and gpsd installed. I set the following in /etc/default/gpsd
# Devices gpsd should collect to at boot time.
# They need to be read/writeable, either by user gpsd or the group dialout.
DEVICES=""
DEVICES="/dev/ttyACM0"

# Other options you want to pass to gpsd
GPSD_OPTIONS=""
GPSD_OPTIONS="-n --listenany -D 255"

# Start the gpsd daemon automatically at boot time
START_DAEMON="true"

# Automatically hot add/remove USB GPS devices via gpsdctl
USBAUTO="true"


Despite the --listenany (also tried -G) the gpsd process only listens on the localhost:

root@navigator:/usr/local/src/gpsd-3.9# ps -ef | grep gpsd
gpsd 9744 1 3 20:38 ? 00:00:26 /usr/sbin/gpsd -n --listenany -D 255 /dev/ttyACM0

There is no sign of a *:gpsd bind.

So it looks as though the -G option to gpsd is broken, I have tried gettting the source and to compile with scons but the source includes python 2 which breaks the build. Also the binary should be fixed. Can anyone assist?
