This is a page has been migrated to readthedocs:https://github.com/navit-gps/navit/pull/883 . It is only kept here for archiving purposes.

This is a tutorial for Navit on WinCE/WinMobile. If want just want to download a cab file see WinCE.

This page explains how to build Navit for WinCE/WinMobile with cegcc.

In November 2009 versions compiled using arm-cegcc-gcc (both revision 1214 and release 0.59.1) had problems (threw exception_datatype_misalignment and caused access violations).
Using the variant arm-mingw32ce of CeGCC 0.59.1 it was possible to build a working executable which can be debugged.
The automatic builds from the subversion repository seem to use an adjusted? version arm-wince-mingw32ce (see build logs).

Building using arm-mingw32ce[edit]

Install arm-mingw32ce[edit]

 mkdir -p navit
 cd navit
 export NAVIT_PATH=`pwd`
 wget -c https://sourceforge.net/projects/cegcc/files/cegcc/0.59.1/mingw32ce-0.59.1.tar.bz2/download
 tar xjf mingw32ce-0.59.1.tar.bz2

Building Navit using Cmake[edit]

#!/bin/bash
export NAVIT_PATH="/usr/src/navit"
export MINGW32CE_PATH="/opt/mingw32ce"
export PATH=$PATH:$MINGW32CE_PATH/bin 
 
cd $NAVIT_PATH
if [ ! -e build ]; then 
  mkdir build;
fi;
cd build
 
cmake \
-DCMAKE_TOOLCHAIN_FILE=$NAVIT_PATH/Toolchain/arm-mingw32ce.cmake \
-Dsvg2png_scaling:STRING=0,16 \
-Dsvg2png_scaling_nav:STRING=32 \
-Dsvg2png_scaling_country:STRING=16 \
$NAVIT_PATH
 
make

For subsequential builds it is sufficient to issue "make" in the build directory. A rerun of cmake is only neccessary if parameters are changed.

Remote Debugging[edit]

Download the debugger provided by the CeGCC project:

 cd $NAVIT_PATH
 wget -c https://sourceforge.net/projects/cegcc/files/cegcc/0.59.1/gdb-arm-0.59.1.tar.bz2/download
 tar xjf gdb-arm-0.59.1.tar.bz2

Start navit (from SD card) in debug server at target (using TCP port 9999):

 gdbserver :9999 "\Mounted Volume\navit\navit.exe"

Execute remote debugger at host, if target's IP address was 192.168.1.112:

 $NAVIT_PATH/opt/mingw32ce/bin/arm-mingw32ce-gdbtui $NAVIT_PATH/navit/navit.exe -eval-command="target remote 192.168.1.112:9999"

Building using arm-cegcc[edit]

Building cegcc[edit]

Set the install path to where you want to install cegcc:

 export CEGCC_PATH=/usr/local/cegcc
 svn co -r 1214 https://cegcc.svn.sourceforge.net/svnroot/cegcc/trunk/cegcc
 mkdir -p cegcc-builds
 cd cegcc-builds
 ../cegcc/src/build-cegcc.sh --prefix=$CEGCC_PATH --components="binutils bootstrap_gcc w32api newlib dummy_cegccdll gcc cegccdll cegccthrddll libstdcppdll profile"

If you get an error like "'makekinfo' is missing on your system" although makeinfo is available (happened with openSUSE 11.2 and Debian Lenny, both 32 bit), add a workaround to the script src/newlib/missing. Insert a new line after the line " makeinfo)":

    "$@" && exit 0

If you get an error like "arm-cegcc-windres: Can't detect architecture", apply the patch file you find on http://sourceforge.net/tracker/?func=detail&atid=865516&aid=2574606&group_id=173455

Building libraries[edit]

November 2009: The libraries below are not needed anymore since navit brings its own version of glib.
The libraries require additional (not published or not existing) patches to build. Just skip to section Building Navit.

These are the libraries needed and versions which should work:

• zlib-1.2.3
• libiconv-1.9.1
• gettext-0.17
• libpng-1.2.34
• tiff-3.8.2
• glib-2.18.4

The current versions of these libs don't need many changes, but they all don't know anything about cegcc. Until I found a way to upload the patches, you have to edit the code yourself. Just add "| -cegcc*" to the line containing "-cygwin*" of all files named config.sub. Here is the example for libiconv-1.9.1_cegcc.patch:
