[maemo-developers] Fwd: How to fire up gps daemon from command line - wanna build GPS app on N810

[From: tz]

Oops. excuse this if it is a partial repost.

1. You need to be user, not root to do /usr/libexec/navicore-gpsd-helper.

2. strace-ing it with 2>&1 | grep connect, stat, or open will reveal
debug log directories.  Creating them will have them fill with data.

3. The magic socket is /var/lib/gps/gps_driver_ctrl "P3" turns it on,
"P0" turns it off.  I'm not sure if the space between the P and the 3
is necessary.  You need socat or something else that does unix sockets
since normal things like using the > or >> or even tee won't work.
You need a connect call, not an open.
