hi dario,
i just tried to compile master and your patch. (heaving gpsd installed)
here are some problems:
CC gps.o
gps.c:41: error: 'gps' redeclared as different kind of symbol
/usr/include/gps.h:127: error: previous definition of 'gps' was here
gps.c: In function 'osmo_gpsd_cb':
gps.c:73: warning: implicit declaration of function 'gps_waiting'
gps.c: In function 'osmo_gpsd_open':
gps.c:123: warning: implicit declaration of function 'gps_stream'
gps.c:123: error: 'WATCH_ENABLE' undeclared (first use in this function)
gps.c:123: error: (Each undeclared identifier is reported only once
gps.c:123: error: for each function it appears in.)
1. the symbol "gps" is used as structure instance for struct osmo_gps.
it is also used in an enum declaration at /usr/include/gps.h:
...
enum {gps, glonass, unknown} system;
...
2. the declarations 'gps_waiting', 'gps_stream', 'WATCH_ENABLE'
are not
defined at gps.h
this is maybe one reason why i failed to write gpsd support. symbols in
the howtos and examples were missing. here is the latest version i got
from the gentoo repository:
* sci-geosciences/gpsd
Latest version available: 2.32
Latest version installed: 2.32
Size of files: 603 kB
Homepage: http://gpsd.berlios.de/
Description: GPS daemon and library to support USB/serial GPS
devices and various GPS/mapping clients.

any ideas?

Everything works for me:
ironlady:~/Projects/mobile/osmocom/src$
ironlady:~/Projects/mobile/osmocom/src$
ironlady:~/Projects/mobile/osmocom/src$ grep system /usr/include/gps.h
* Values for "system" fields. Note, the encoding logic is senstive to
the
int system;
int system; /* Which system is it? */
int system; /* Which system is it? */
ironlady:~/Projects/mobile/osmocom/src$
ironlady:~/Projects/mobile/osmocom/src$
The enum you said is not present in my gpsd include. Instead I have
/*
* Values for "system" fields. Note, the encoding logic is senstive to
the
* actual values of these; it's not sufficient that they're distinct.
*/
#define NAVSYSTEM_GPS 0
#define NAVSYSTEM_GLONASS 1
#define NAVSYSTEM_GALILEO 2
#define NAVSYSTEM_UNKNOWN 3
The symbols you miss, can be found on my system.
ironlady:~/Projects/mobile/osmocom/src$ grep gps_waiting /usr/include/gps.h
extern bool gps_waiting(struct gps_data_t *);
ironlady:~/Projects/mobile/osmocom/src$ grep gps_stream /usr/include/gps.h
extern int gps_stream(struct gps_data_t *, unsigned int, /*@null@*/void *);
ironlady:~/Projects/mobile/osmocom/src$ grep WATCH_ENABLE
/usr/include/gps.h
#define WATCH_ENABLE 0x0001u /* enable streaming */
ironlady:~/Projects/mobile/osmocom/src$
ironlady:~/Projects/mobile/osmocom/src$
ironlady:~/Projects/mobile/osmocom/src$

My gpsd version is much more recent:
ironlady:~/Projects/mobile/osmocom/src$ rpm -q gpsd
gpsd-2.95-2.fc14.i686
ironlady:~/Projects/mobile/osmocom/src$

Then try to find what's the minimum version (see api changes in the
gpsd history I guess) and make sure in the configure to check it.
Nice suggestion. I will add this feature and submit a new version of the
patch. This means that Andreas will not be able to compile the support
anymore, until its debian gets aligned :).

Well, the current situation is _worse_ ... it tries to compile the support
and fails ...
And it's gentoo not debian :)
Also if you enable the support of experimental packages for gpsd, it does
install the 2.95
Cheers,
Sylvain
