GDAL/OGR port for Window CE
Mateusz Loskot, mateusz@loskot.net
=============================================================================

GDAL/OGR for Windows CE features:
- all base OGR API and modules (port, ogr)
- subset of OGR drivers (ogr\ogrsf_frmts): generic, mitab, shape
- wcelibcex - extension to C library on Windows CE

Features not included in GDAL/OGR for Windows CE:
- in fact, this port does not include rasters support
- GEOS has not been ported yet, so OGR for Windows CE
  compiles without GEOS support (work is in progres)
- OGR drivers not listed in features list above

I'd like to thank:
==================
- Frank Warmerdam for GDAL/OGR and priceless support he provide me
- Taxus SI Ltd. from Poland for their great support
- Users from IRC #gdal channel
- All users, testers and contributors

- wcelibcex
  Windows CE C Library Extensions provide some functions missing in
  the standard C library on Windows CE devices, e.g. time, ctime, mkdir, etc.
  It will be hosted as a separate project:
  http://sourceforge.net/projects/wcelibcex

- wce_test_lib
  Sample application to test gdalce.lib - static library - build with
  makefile.evc4.

- wce_test_dll
  Sample application to test gdalce.dll - DLL - build with makefile.evc4.
  NOTE: Currently, DLL produced that way seems to be broken and can not
  be loaded properly. So, if you are NMake/Makefiles guru you're
  welcome to fix it. Thanks in advance!

- evc4_gdalce_lib*
  Project file for eMbedded Visual C++ 4.0 to build GDAL/OGR as a static
  library.
  
- evc4_gdalce_lib_test*
  eMbedded Visual C++ 4.0 project of sample application to test static
  library built using evc4_gdalce_lib project.

- evc4_gdalce_dll*
  Project file for eMbedded Visual C++ 4.0 to build GDAL/OGR as a DLL.
  
- evc4_gdalce_dll_test*
  eMbedded Visual C++ 4.0 project of sample application to test DLL built
  using evc4_gdalce_dll project.

(***) Project files for eMbedded Visual C++ 4.0 are not compatible
      between versions 3.0 and 4.0. So, in order to build GDAL/OGR
      using eVC++ 3.0 you have to create project files from scratch.

=============================================================================
Building GDAL/OGR for Windows CE .NET:
=============================================================================

Note: Windows CE .NET is a version 4.0 - 4.2 and it's only a name, so 
there is no .NET Framework dependency! Starting from Windows CE 5.0,
Microsoft has removed .NET from the name of the system.

Requirements:
=============

First, you need to install following software on your machine:

0. Compilation box running Windows NT/2000/XP 

1. Microsoft eMbedded Visual C++ 4.0 - it's free
http://www.microsoft.com/downloads/details.aspx?FamilyID=1DACDB3D-50D1-41B2-A107-FA75AE960856

2. Microsoft eMbedded Visual C++ 4.0 Service Pack 4
http://www.microsoft.com/downloads/details.aspx?FamilyID=4A4ED1F4-91D3-4DBE-986E-A812984318E5

3. SDK for Windows Mobile 2003-based Pocket PCs
http://www.microsoft.com/downloads/details.aspx?FamilyId=9996B314-0364-4623-9EDE-0B5FBB133652

Note: I have only tested OGR port with Pocket PC 2003 SDK but there should not be any
problem with building it using other Windows CE SDKs. If you've managed to build OGR port
using other SDKs pleaes let me know.

4. The Run-time Type Information library for the Pocket PC 2003 SDK
http://support.microsoft.com/default.aspx?scid=kb;[LN];830482

5. I also recommend to use STLport
Here is some introduction: 
http://mateusz.loskot.net/2005/12/25/how-to-use-stlport-with-evc/
it refers to my article on http://www.pocketpcdn.com

Building with makefiles:
========================

1. Open command line (cmd.exe) on your Windows box
and go to gdal sources directory e.g. C:\gdal

2. Run configuration script for ARM target. It's default location is:
C:\Program Files\Microsoft eMbedded C++ 4.0\EVC\wce420\bin\WCEARMV4.BAT

Now, runs some commands to check if everything is configured well: 

C:\gdal>clarm.exe /?
Microsoft (R) C/C++ Optimizing Compiler Version 12.20.9615 for ARM
Copyright (C) Microsoft Corp 1984-2002. All rights reserved.

C:\gdal>echo %PLATFORM%
POCKET PC 2003

C:\gdal>echo %OSVERSION%
WCE420

3. Build
C:\gdal>nmake /f makefile.evc4

4. If everything went without any errors you should have
following files in gdal root directory (C:\gdal):
gdalce.lib - static library (PREFERED)
gdalce13.dll - Dynamic-Link Library (DLL) (See IMPORTANT note)
gdalce_i.exp - export file for DLL
gdalce_i.lib - import library for DLL

(***) IMPORTANT!
Currently gdalce13.dll built with NMake seems to be broken.
So, if you want to use GDAL/OGR for Windows CE as DLL please
use eVC++ 4.0 project file from evc4_gdalce_dll directory at the moment.
This issue is known and waiting for fix :-)

Summary of building GDAL/OGR for Windows CE:
============================================
1. Static Library:
- using makefile.evc4
- using eVC++ 4.0 project file in evc4_gdalce_lib directory
2. DLL:
- using eVC++ 4.0 project file in evc4_gdalce_dll directory
- building with makefile.evc4 is currently broken
