Hi Graham,

Are you still interested in develop the compatibility with the latest gpsd?

I have uploaded to svn a version of my trial with gpsd 2.xx as a branch of
the head version I uploaded past weekend.

This version works quite well if I poll gpsd with a timer every 500 ms, but
my goal is to use a QSocketNotifier to know when ther is new data form gpsd.
I have got problems with this because the activated() signal is never
called. Things that I notice:
- The socket descriptor given by gpsd is allwais 0. I know that this is a
valid value, but is it not reserved for standar input?
- When I start qpegps from the shell (./qpegps) in order to see the messages
from qDegug sentences, it starts to receive QSocketNotifier notifications
after I press return on the shell (qpegps is the running process of thar
shell, that is I don't run in in background with &). After pressing return,
all works ok.

If you (or someone else) can use my code as starting point it is on:
https://svn.sourceforge.net/svnroot/qpegps/branches/gpsd2xx/qpegps

This code is based on trunk revision 237 that I uploaded to svn on november
18, I'm going to continue adding track animation support from v0.9.2.3.3 to
this version, but as long as you only need to work on client.h/cpp and
gpsstatus.h/cpp files, we can work together.

Regrards,
ztep
