Re: [gpsd-users] Problem running on CentOS 7

[Vaish, Atul]

Hello Gary 
 starting  using my intel id  where I work and  porting this  gpsd task is one 
of my assignments.  

Build logs are attached. 

gpsd$ gpsd -V
gpsd: 3.16 (revision 3.16)
gpsd$ gpsmon -V
gpsmon: 3.16 (revision 3.16)
gpsd$ cgps -V
cgps: 3.16 (revision 3.16)

Above  looks to be from the build gpsd that I built using scons  command line .

When I use "sudo apt-get install gpsd gpsd-clients python-gps" ,I get version 
3.15 .
address@hidden:~$ cgps -V
cgps: 3.15 (revision 3.15-2build1)
address@hidden:~$ gpsmon -V
gpsmon: 3.15 (revision 3.15-2build1)
address@hidden:~$ gpsd -V
gpsd: 3.15 (revision 3.15-2build1)
address@hidden:~$

address@hidden:~$ pgrep gpsd
2541

The output from gpsmon and cgps in above case , are in attached JPEG files 
(still I see "NO FIX" after 10-15 mins,  am I missing something  here?)   .
 Hope that should be fine as copy-paste the terminal output wasn't the option 
here for me.  


With 3.16 Version (which I installed using scons command line) , still shows 
the issue as below while running gpsmon and cgps at different times

On Android Porting ==>
Have enabled CONFIG_USB_SERIAL_GARMIN=y in kernel to make it Garmin specific 
kernel driver, is this enough  ? or  there is more to customization as u 
mentioned ? 


Thanx a Lot for your support

OK, sort of.

Pretty hard for anyone to cut past from an image to show you where the problems 
are.  Next time simple text cut and paste please.

Your results make no sense, your cgps does not match your gpsmon.  They could 
not possible be from the same running gpsd near the same time.

I'm guessing you ran gpsmon when gpsd is not running.  All that tells me is 
your Garmin US is up and running with a proper driver, but tells me nothing 
about your gpsd.

And what I also asked for, the most important thing I asked for, is the log of 
your build.

Also useful is to print the versions after your install, like this:

# gpsd -V
gpsd: 3.17~dev (revision release-3.16-564-g3798287)

# gpsmon -V
gpsmon: 3.17~dev (revision release-3.16-564-g3798287)

# cgps -V
cgps: 3.17~dev (revision release-3.16-564-g3798287)

That will not happen easily.  Garmin USB requires a Garmin specific kernel 
driver.  So to get this to work on Android you need to compile a custom kernel.
