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.
On the Nokia itself
install subversion
- 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
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 myuser root@i386 # su - scratchboxuser
- set up the SDK
scrtchboxuser@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 EOF apt-get update
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 kdepimlibs5-dev svn co https://svn.kde.org/home/kde/trunk/kdesupport cd kdesupport cmake . && make && make install 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.
re-install 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
install kdepim
cd svn co https://svn.kde.org/home/kde/branches/KDE/4.1/kdepim cd kdepim cmake . 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.
