Foxtrotgps doesn't connect to my internal GPS data

[Tirzah Yanchyshyn]

I'm new to linux and my device uses Debian 10. It has an internal GPS that is working well...still it seems foxtrotgps doesn't 'see' the gps data. I don't know if I need to change a setting or run a command...also gpsd is installed and updated. Any ideas, anyone?

Have you checked that other gpsd clients like cgps are working?

Try running foxtrotgps in a terminal, you should see this message:

   connection to gpsd SUCCEEDED

You could also install foxtrotgps-dbgsym, load foxtrotgps in a debugger
like gdb, set a breakpoint for cb_gpsd_data, run foxtrotgps and step
over the libgps calls to see what happens when reading data.

I don't have a real GPS, but FoxtrotGPS is able to connect via gpsd to
a virtualgps and read data correctly on my system.

You might want to consider updating to a newer version of Debian if
possible. In addition FoxtrotGPS is not well maintained and will
probably be removed from Debian 13 because it needs porting to GTK 4
but no-one has been motivated enough to do it yet. So you might want
to look into alternatives that you could use instead.

Dear Paul

Thank you very much for your suggestions - we've tried running the tests you said. We've also checked that all the parameters were set properly, file permissions are correct and gpsd seems to be running fine. Still no connection to our built-in gps. Maybe it really is some incompatibility with Debian 10...

Anyway, we've resigned ourselves to manually plotting our GPS fixes on the foxtrotgps map. It's still the best app of its kind that we've found.

Kind regards,
Serge & Tirzah

Check your system logs to see if there is an AppArmor/SELinux denial.

If you have a spare external USB GPS available, maybe try using that
instead, to see if it is a software problem or a GPS problem.

You could also download a Debian 12 live image, boot it and try to see
if that works too. Maybe also try Debian 10/11 live images. You can do
`apt update` and `apt install gpsd foxtrotgps` on the live images too.

Since the FoxtrotGPS POIs are just in an sqlite database, it should be
easy to automate the conversion of GPS fixes to FoxtrotGPS POIs, the
georss2foxtrotgps-poi script should be good inspiration for that. If
you write a new script for it, we can add that to the repository for
other folks to use too.

FoxtrotGPS is quite a simple app, you might be better served by
something with more features and maintainers like opencpn or qgis.

Hi Paul

Our internal GPS works well, without gpsd, and runs on the command line. So technically speaking, we can do without an app if we have maps on hand.

We tried OpenCPN first - for days we tried installing it from different sources and also tried many other gps apps. We've been looking at forums for days too and nothing we try seems to work. We also just got Debian 10 and are new to Linux. So changing the operating system now is not on the table for us.

Our external gps are in storage so we will have to try your other suggestions a bit later.

If we have breakthrough, we'll let you know so others can benefit.

Kind regards,
S & T

If the GPS works without gpsd but doesn't work with gpsd/cgps, then
a newer version of gpsd might help. There is a very slightly newer
version in the buster-backports repository, instructions here. For
a much newer gpsd, you would need to backport it yourself and then
backport foxtrotgps and other gpsd clients to the new version.

https://backports.debian.org/Instructions/
https://wiki.debian.org/SimpleBackportCreation

There is an OpenCPN build in buster-backports-sloppy repository,
the instructions above should help you install it.

The qgis package is available in buster itself.

Good luck with everything else.
