View source for Maemo SDK+ installation on Debian (AMD64)

The Maemo SDK+ package includes scratchbox 2 and Qt, but it will only install on 32-bit platforms.  If you're running Debian with a 64-bit kernel, Maemo SDK+ can be installed into a chrooted 32-bit environment that sits on top of your 64-bit platform.  This guide takes you through all the steps to the point of compilation and running the test.

===Building the chrooted platform===
All steps in this section are executed as root, directly on the host.

Using lenny (old, from the archives):
 # aptitude install debootstrap
 # debootstrap --arch i386 lenny /srv/lenny-ia32 <nowiki>http://archive.debian.org/debian/</nowiki>
 # echo "deb <nowiki>http://maemo-sdk.garage.maemo.org/download/host debian-lenny</nowiki> free" >> /srv/lenny-ia32/etc/apt/sources.list
 # aptitude install schroot

Or using sqeeze (current stable):
 # aptitude install debootstrap
 # debootstrap --arch i386 squeeze <nowiki>/srv/lenny-ia32 http://ftp.debian.org/debian/</nowiki>
 # echo "deb <nowiki>http://maemo-sdk.garage.maemo.org/download/host debian-squeeze</nowiki> free" >> /srv/lenny-ia32/etc/apt/sources.list
 # aptitude install schroot
You may want to adjust the /srv/lenny-ia32 directory, but then you'd have to adjust it in the rest of the instructions as well (together with any other lenny references if you like).
  
 <s># cat >> /etc/schroot/schroot.conf <<EOF

===Installing Maemo SDK+===
While still logged in as root on the host:
 # schroot -c lenny
 (lenny)~ #
or
 # chroot /srv/lenny-ia32/ /bin/bash
 (lenny)/ #

You are now logged in as root in the chrooted environment as  ''root''.
 (lenny)~ # aptitude update
 (lenny)~ # aptitude install maemo-sdk
 (lenny)~ $ maemo-sdk reload catalogue
 (lenny)~ # maemo-sdk list available tools
 etch
 etch-2008
 lenny-2009-1

Install tools:
 (lenny)~ # maemo-sdk --mirror <nowiki>http://archive.debian.org/debian/ install tools lenny-2009-1</nowiki>

 (lenny)~ # maemo-sdk list available toolchains
 arm-2005q3
 arm-2007q3
 i386-2007q3

Install toolchain:
 (lenny)~ # maemo-sdk install toolchain arm-2007q3

As the SDK needs to use sudo to gain root access later, we need to configure sudo:
 (lenny)~ # visudo
You will be in an editor session now. Modify the file so that it looks like this (remove the comment sign in front of the last lign):
 Defaults	env_reset
 root	ALL=(ALL) ALL
 %sudo ALL=NOPASSWD: ALL

Now, log out of the schroot section, log out of the root account, and as a normal user on the host, log in to the chroot:
 (lenny)~ # logout
 # logout
 $ schroot -c lenny
 (lenny)~ $
You are now logged in <s>as root in</s> to the chrooted environment as a ''normal (non-root) user''.

Now, choose a rootstrap to install:
 (lenny)~ $ maemo-sdk list available rootstraps

You get a list of rootstraps
 diablo4.1.2_armel
 diablo4.1.2_i386
 diablo4.1.1_armel
 diablo4.1.1_i386
 diablo4.1_armel
 diablo4.1_i386
 fremantle5.0minimal_armel
 fremantle5.0minimal_i386
 fremantle5.0beta1_armel
 fremantle5.0beta1_i386
 scirocco2.2_armel
 scirocco2.2_i386
 mistral2.0_armel

Now, install your desired rootstrap. For example

 (lenny)~ $ maemo-sdk install rootstrap '''''diablo4.1.2_armel'''''
 (lenny)~ $ sb2 -eR apt-get update
 (lenny)~ $ sb2 -eR apt-get install maemo-sdk-runtime maemo-sdk-dev maemo-sdk-debug

===Preparing host for target GUI===
As root on the host:
 # aptitude install xserver-xephyr

===Building Maemopad to test the build environment===
As a normal (non-root) user on the host:
 $ schroot -c lenny
You are now logged in <s>as root in</s> to the chrooted environment as a ''normal (non-root) user''.
 (lenny)~ $ mkdir -p ~/src/mytest
 (lenny)~ $ cd ~/src/mytest
 (lenny)~/src/mytest $ sb2 -eR apt-get update
 (lenny)~/src/mytest $ sb2 apt-get -eR build-dep maemopad
 (lenny)~/src/mytest $ sb2 apt-get source maemopad
 (lenny)~/src/mytest $ cd maemopad-2.6
 (lenny)~/src/mytest/maemopad-2.6 $ export SBOX_REDIRECT_FORCE=/usr/bin/perl
 (lenny)~/src/mytest/maemopad-2.6 $ sb2 dpkg-buildpackage -rfakeroot -d -b

===Running Maemopad===
As ''user'' on the host:
 $ Xephyr :2 -host-cursor -screen 800x480x16 -dpi 96 -ac &
 $ schroot -c lenny
You are now logged in <s>as root in</s> to the chrooted environment as a ''normal (non-root) user''.
 (lenny)~ $ export DISPLAY=:2
 (lenny)~ $ cd ~/src/mytest/
 (lenny)~/src/mytest $ sb2 -eR dpkg -i maemopad_2.6-3+0m5_armel.deb
 (lenny)~/src/mytest $ maemo-sdk start gui
<s>Notice that Maemopad appears in the x11 window.</s><br />
Now you can launch MaemoPad from the Extras menu in the Xephyr window.
 (lenny)~/src/mytest $ maemo-sdk stop gui

===Installing Qt===
As ''root'' in the chrooted environment:
 (lenny)~ # aptitude install qt4-dev-tools

===Known Issues===
The procedures above work quite well, other than the fact that the following scripts are missing from the chrooted environment:
 * run-standalone.sh
 * af-sb-init.sh
They don't seem to be important.. just a cosmetic matter.

I have ~/.maemo-sdk/rootstraps/armel/diablo4.1.2_armel/usr/bin/run-standalone.sh and ~/.maemo-sdk/rootstraps/armel/diablo4.1.2_armel/usr/bin/af-sb-init.sh 
I'm not sure where I got them --[[User:swajime|SwaJime]] 22:50, 5 August 2010 (UTC)
