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.


[edit] Overview

  • 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.

[edit] On the Nokia itself

[edit] 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

[edit] install subversion

ssh root@localhost
apt-get install subversion

[edit] In scratchbox

You cannot install scratchbox on an X64 computer, so, install an i386 into a VMWare virtual machine. The following describes how to install scratchbox into a SUSE 11 32bit installation. It might work same or similar with any Linux.

[edit] Hello world

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

  • Set up scratchbox
root@i386 # useradd -m scratchboxuser
root@i386 # wget http://repository.maemo.org/stable/diablo/maemo-scratchbox-install_4.1.2.sh
root@i386 # chmod 777 maemo-scratchbox-install_4.1.2.sh
root@i386 # ./maemo-scratchbox-install_4.1.2.sh -s /scratchbox
root@i386 # /scratchbox/sbin/sbox_adduser scratchboxuser
root@i386 # su - scratchboxuser
  • set up the SDK
scratchboxuser@i386 $ wget http://repository.maemo.org/stable/diablo/maemo-sdk-install_4.1.2.sh

Start the install script and accept all choices:

scratchboxuser@i386 $ sh maemo-sdk-install_4.1.2.sh
  • start scratchbox
scratchboxuser@i386 $ /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

[edit] Re-login

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

/scratchbox/sbin/sbox_ctl start

[edit] 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
root@i386 # cp /etc/resolv.conf /scratchbox/etc/resolv.conf

[edit] 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 

[edit] 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.

[edit] 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.

[edit] 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:


[edit] Know-how

[edit] manually dpkg


[edit] kompile kdelibs

[edit] pcre

curl ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-7.9.tar.gz>pcre-7.9.tar.gz
tar xvzf pcre-7.9.tar.gz
cd pcre-7.9
./configure && make && make install

[edit] kdelibs

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

[edit] TroubleShooting

[edit] kernel too old




FATAL: kernel too old

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

[edit] 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.

[edit] 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.
