This article describes how to compile KDEPIM for maemo. It takes the Nokia N810 as example device. It uses the cross-compiling environment scratchbox on an Intel-based computer.


  • garage is where the projects for maemo are hosted. Compare it with sourceforge.
  • diablo is the version of maemo. Compare it with lenny.
  • maemo is the software that runs on a device like Nokia's N810
  • scratchbox is a cross-compiling environment to enable you to create software for maemo on an i386.
  • busybox is a single binary that allows you to run commands like ls, cat and bunzip2
  • hildon is a desktop like plasma

For more information see wikipedia.

On the Nokia itself

install openssh

  • to install openssh on a nokia 810
  • activate the maemo repository in the package manager
    • settings->application manager
    • tools -> application catalog
    • memo extras -> edit -> un-tag "disabled"
    • close
    • browse installable applications
    • all
    • openssh
    • install

install subversion

ssh [email protected]
apt-get install subversion

In scratchbox

You cannot install scratchbox on an X64 computer, so, install an i386 into a VMWare virtual machine. This example uses SUSE 11, but it might work on other distributions as well. The following describes how to install scratchbox into that SUSE 11 32bit installation.

Hello world

First, we want to compile a "hello world" program for the Nokia. Here is how.

  • Set up scratchbox
[email protected] # useradd -m scratchboxuser
[email protected] # wget http://repository.maemo.org/stable/diablo/maemo-scratchbox-install_4.1.2.sh
[email protected] # chmod 777 maemo-scratchbox-install_4.1.2.sh
[email protected] # ./maemo-scratchbox-install_4.1.2.sh -s /scratchbox
[email protected] # /scratchbox/sbin/sbox_adduser scratchboxuser
[email protected] # su - scratchboxuser
  • set up the SDK
[email protected] $ wget http://repository.maemo.org/stable/diablo/maemo-sdk-install_4.1.2.sh

Start the install script and accept all choices:

[email protected] $ sh maemo-sdk-install_4.1.2.sh
  • start scratchbox
[email protected] $ /scratchbox/login
[sbox-DIABLO_ARMEL: ~] > sb-conf select DIABLO_ARMEL
[sbox-DIABLO_ARMEL: ~] > cat > main.c << EOF
#include <stdio.h>

int main()
  printf("hello world");
[sbox-DIABLO_ARMEL: ~] > gcc main.c
[sbox-DIABLO_ARMEL: ~] > file a.out
a.out: ELF 32-bit LSB executable, ARM, version 1 (SYSV), for GNU/Linux 2.6.8, dynamically linked (uses shared libs), not stripped
  • copy the file to your Nokia N810 using scp

=> the file is executable on the Nokia


To re-login after a reboot of your virtual machine run

/scratchbox/sbin/sbox_ctl start

set up repositories

  • Here you should better make a snapshot of your virtual machine.
  • Then create the installation repositories and install cmake:
cat >>/etc/apt/sources.list<<EOF
# repository with experimental kde packages and dependencies
deb binary/
deb http://repository.maemo.org/ diablo free non-free
deb-src http://repository.maemo.org/ diablo free
deb http://repository.maemo.org/extras-devel/ diablo free
deb-src http://repository.maemo.org/extras-devel/ diablo free
deb http://qt4.garage.maemo.org diablo extra
apt-get update
[email protected] # cp /etc/resolv.conf /scratchbox/etc/resolv.conf

install cmake

wget http://www.cmake.org/files/v2.6/cmake-2.6.2.tar.gz
tar xvzf cmake-2.6.2.tar.gz
cd cmake-2.6.2
./bootstrap && make -j4 && make install 

more information

  • You can also choose to add the repositories mentioned in http://www.forwardbias.in/data/articles/qt_on_maemo.txt, but as of 2008-09-07, qmake installed from there crashes with signal 11.
  • You can also choose to build qt on your own, but for me it does not find openssl during its installation process.

Install kde applications

apt-get install shared-mime-info
apt-get install xsltproc
apt-get install libboost-dev
apt-get install libakonadi-dev
apt-get install kdepimlibs5-dev
apt-get install libstreamanalyzer-dev
svn co https://svn.kde.org/home/kde/branches/KDE/4.1/kdepim
cd kdepim
cmake . && make && make install

Here you can get to run singular applications, e.g. ktimetracker.

on the N810 again

Copy the applications and libs to the Nokia. Singular applications work, e.g. ktimetracker. Put all libraries and executables onto your flash storage (/media/mmc1) and start it:



manually dpkg


kompile kdelibs


curl ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-7.7.tar.gz>pcre-7.7.tar.gz
tar xvzf pcre-7.7.tar.gz
cd pcre-7.7
./configure && make && make install


svn co https://svn.kde.org/home/kde/branches/KDE/4.1/kdelibs
mkdir kdelibs-build
cd kdelibs-build
cmake ../kdelibs
make install


kernel too old




FATAL: kernel too old

This happened for me with SLES 10. Better use SUSE 10.3 or SUSE 11.

unable to install maemo-sdk-dev

On SLES 10, I got

Processing was halted because there were too many errors.
E: Sub-process /scratchbox/devkits/debian-etch/bin/dpkg returned an error code (1)
E: Unable to install maemo-sdk-dev on DIABLO_ARMEL target.
E: Please check the sources.list for errors.
E: Scratchbox login returned error 100.

In this case, change your distribution and start again.

ld terminated with signal 9

Should you get

collect2: ld terminated with signal 9 [Killed]

Increase the amount of memory for the virtual machine, 512MB is not always enough.
