That sounds great, also Tim Sutton and I will be working in a user interface
lite and a port to openmoko

Godofredo,

FYI, I'm doing similar work as you. But I'm trying to avoid direct port
of QGIS for Windows CE (and other mobile platforms) because in my
opinion the original version is too heavy and needs to be "rewritten"
for small resources. Plus, I want to get multi-threaded solution, etc.

My aim is to keep API as compatible as possible, but performance is the
first issue I'm focusing now.

I'm looking on this issue. I'll be back to you tomorrow with results.

Problems linking to geos.lib

2008-07-26T16:40:11Z

Hi:

I'm working in a Quantum Gis API port for windows CE,
I'm using your visual studio solution to compile proj,
geos, and gdal.

Using gdal and proj, works as expected but when linking
a sample program that calls geos:geom:geosversion method
I always get the following message:

File "example" cannot be opened. Either it is not signed
with a trusted certificate, or one of its components cannot
be found. You might need to reinstall or restore this file.

Removing the function and the includes results in the
application running with no problems.

Any ideas, to solve this problem? any help will be appreciated

Regards
Godofredo Contreras

GPS on Trimble XC unit

2007-11-04T12:33:59Z

Hello,

     I was able to configure GPS on Trimble Recon GPS XC unit and run the sample code posted by Mateusz
     using GPS intermediate driver.Thanks to Mateusz.I would like to share information and mention few
     problems that i ran into,In case if anyone plans to use Trimble Recon unit.

    The GPS receiver goes into the front slot of the unit.The unit hardware port has to be configured on COM2.
    In order to use the GPS and get position fixes you have install GPS controller software from the trimble
    site.It could be found on http://trimble.com/support_trl.asp?Nav=Collection-32053. Download and install
    the v2.11 GPS controller,software for windows CE.The GPS unit is capable to get NMEA messages.

    To run the application on the unit,we have to make sure the Program port is set to GPD1,so that multiple
    applications can use the GPS receiver.onece the program is compiled you might run into some errors such
"gpsid.obj : error LNK2019: unresolved external symbol GPSCloseDevice referenced in function wmain
    gpsid.obj : error LNK2019: unresolved external symbol GPSOpenDevice referenced in function wmain
    Windows Mobile 5.0 Pocket PC SDK (ARMV4I)\Debug/gpsid.exe : fatal error LNK1120: 2 unresolved
externals"

    there are 2 possible ways to solve these errors.

1. please type in the library name (C:\Program Files\Windows CE Tools\wce500\Windows Mobile 5.0 Pocket
PC SDK\Lib\ARMV4I\gpsapi.lib) so it would appear in the linker's command line.You can do so in
Link/Input/Additional dependencies. Then navigate to Linker/Command Line, you should see this library in
    the list among some libraries VS adds by default.

2. Please add the following to one of your source-file:
   #pragma comment(lib, "Ws2_32.lib")
   or you can add this lib (Ws2_32.lib) to the linker settings...
   You also should change the subsystem in your linker settings from "WINDOWS" to "CONSOLE"
   (If you have a "_tmain" instead of a "_tWinMain").

Hi Vishal, John,

We can have some small meeting today, ideally using skype call service.
I'm available all day except during FDO PSC meeting starting at 7pm
and it will probably last for ~1 hour.
So, please call me any time except between 7-8pm

Vishal, yesterday I posted gpsid sample program to the SVN + small
announcement to the list. Have you got it (assuming you've subscribed
the list) ?

p.s. If you want to reply to the list but not to the original sender,
use Reply To All, instead to Reply.

Cheers

Hi,

I added small console application called gpsid to the MOSS4G tests.
This sample presents how to use the new GPS Intermediate Driver.

Also, here we have Wiki page dedicated to GPS support discussion:
