Some scenarii, like building an RTK base, does not require a gpsd
daemon, but just a few python based tools (e.g. the python scripts
to configure a GNSS device).
Add an option to enable or disable building and instaling the daemon.
We make it enabled by default, for legacy purposes.
When the daemon is installed, it also installs a few ancillary helpers,
which need some of the clients (e.g. the udev rule will use gpsdctl), so
ensure they are enabled with the daemon.
Speaking of the udev rule: without the daemon, it does not need to be
installed, so only try to fix its mode when the daemomn is installed.
Similarly for systemd, no need to install the drop-in when the daemon is
not installed. And for sysv init, no need for a startup script without
the daemon either.
Now that everything is optional, daemon, clients, and python stuff, we
need to ensure that at least something is installed. The obvious
solution would be to ensure that the daemon is installed, but that
causes conflicts in the Kconfig depencies (elided for readability):
config BR2_PACAKGE_GPSD
bool "gpsd:
select BR2_PACKAGE_GPSD_DAEMON if ! BR2_PACKAGE_GPSD_CLIENTS \
&& ! BR2_PACKAGE_GPSD_PYTHON
config BR2_PACKAGE_GPSD_DAEMON
bool "daemon"
select BR2_PACKAGE_GPSD_CLIENTS
would cause errors like:
package/gpsd/Config.in:27:error: recursive dependency detected!
package/gpsd/Config.in:27: symbol BR2_PACKAGE_GPSD_DAEMON is selected by BR2_PACKAGE_GPSD_CLIENTS
package/gpsd/Config.in:226: symbol BR2_PACKAGE_GPSD_CLIENTS is selected by BR2_PACKAGE_GPSD_DAEMON
So we chose the next best option: ensure that the clients get built, if
nothing else does.
