What does strace show? Is there anything in /var/log/syslog/messages?

You'll find my strace output attached. From the end of the strace, it seems that I the version string should be printed, although there's nothing appearing on my terminal:

access("/etc/selinux/config", F_OK)     = 0
access("/etc/system-fips", F_OK)        = -1 ENOENT (No such file or directory)
fstat(1, {st_mode=S_IFCHR|0666, st_rdev=makedev(0x1, 0x3), ...}) = 0
ioctl(1, TCGETS, 0x7ffe619f9f40)        = -1 ENOTTY (Inappropriate ioctl for device)
write(1, "gpsd: 3.17 (revision 3.17)\n", 27) = 27
exit_group(0)                           = ?
+++ exited with 0 +++

There are also some other errors in the trace, like ENOTTY... maybe that's the source of the problem?

Also, I don't have a /var/log/syslog dir on my machine. Was it supposed to have one?

For comparison, I asked my collegue to run "strace gpsd -V" on his machine that has the behavior I'm expecting. The results are also attached.

Note that `systemctl status gpsd` should also give you a clue.

I can make gpsd work through systemctl. There I can see the expected outputs there, but I would like to run it on foreground and from my terminal to debug a program of mine that will somehow interact with gpsd.

Best,

Ellon
