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

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

Install arm-mingw32ce

mkdir -p navit
cd navit
export NAVIT_PATH=`pwd`
wget -c
tar xjf mingw32ce-0.59.1.tar.bz2

Building Navit

svn co
cd $NAVIT_PATH/navit
export PATH=$NAVIT_PATH/opt/mingw32ce/bin:$PATH
export STRIP=arm-mingw32ce-strip
export RANLIB=arm-mingw32ce-ranlib
export CXX=arm-mingw32ce-g++
export CC=arm-mingw32ce-gcc
export AR=arm-mingw32ce-ar
export WINDRES=arm-mingw32ce-windres
export CFLAGS="-DPATH_MAX=253 -g"
./configure --prefix=$NAVIT_PATH --host=arm-pe-wince --enable-support-libc --disable-vehicle-file --enable-avoid-unaligned --enable-avoid-float \
  --enable-cache-size=10485760 --enable-svg2png-scaling=16,32,48 --enable-svg2png-scaling-nav=32 --enable-svg2png-scaling-flag=16 --with-xslts=windows 2>&1 \
  | tee configure-mingw32ce.log

Apply workarounds described in next section.

make -j

Copy $NAVIT_PATH/navit/navit/navit.exe to your target.


Add to file navit/util.c:

#include <sys/types.h>

Replace g_assert with dbg_assert in file navit/map/mg/street.c.

On debian systems create a script saxon like below somewhere in the PATH:

#! /bin/sh
if test "$1" = "-snone" ; then
    saxon-xslt $*

Ignore errors about undefined reference to `deflateInit2_' and others since they come from the maptool which isn't requiered on WinCE.

Remote Debugging

Download the debugger provided by the CeGCC project:

wget -c
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

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

Building using arm-cegcc

Building cegcc

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

export CEGCC_PATH=/usr/local/cegcc
svn co -r 1214
mkdir -p cegcc-builds
cd cegcc-builds
../cegcc/src/ --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

Building libraries

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:

Building Navit

svn co
cd navit

Add | -cegcc* to all files named config.sub as for the libraries.

WINDRES=arm-cegcc-windres ./configure --disable-vehicle-file --host=arm-cegcc --prefix=$CEGCC_PATH 2>&1 | tee configure-cegcc.log

Add to navit\support\wordexp\glob.h:

|| defined __CEGCC__

Change include in navit\vehicle\wince\vehicle_wince.c:

#include <sys/io.h>

Add to navit\file.c:

&& !defined __CEGCC__
make -j

November 2009: Navit.exe stops early due to exception_datatype_misalignment.
