    Revision as of 18:32, 20 January 2009

    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.

    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.

    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 root@localhost
    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
    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");
    }
    EOF
    [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

    Re-login

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

    /scratchbox/sbin/sbox_ctl start
    /scratchbox/login
    

    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 http://93.157.1.37/~marijn/maemo 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
    EOF
    apt-get update
    
    root@i386 # 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

    cd
    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:

    EXPORT LD_LIBRARY_PATH=.
    ./ktimetracker

    kompile kdelibs

    pcre

    cd
    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
    

    kdelibs

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

    TroubleShooting

    kernel too old

    If

    cmake 
    

    delivers

    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.
