This document describes how to setup the CSSU-thumb toolchain (gcc4.7.2-linaro) in scratchbox.

1. You need to have [http://wiki.maemo.org/Documentation/Maemo_5_Final_SDK_Installation ScratchBox] environment already set up.

2. Download [http://maemo.merlin1991.at/cssu/develdebs/gcc-4.7.2_fremantle_armel/linaro-4.7-2012.07-fremantle-armv7a.tar.bz2 gcc-4.7.2-linaro toolchain] and extract it under /scratchbox/compilers (may need root privileges for extracting there)
 tar xvf linaro-4.7-2012.07-fremantle-armv7a.tar.bz2

3. Create new ScratchBox target FREMANTLE_ARMEL_GCC472

- Login to ScratchBox

$ /scratchbox/login

- Create new ScratchBox target

[sbox->:~]sb-conf st FREMANTLE_ARMEL_GCC472 -c linaro-4.7-2012.07-fremantle-armv7a -d qemu:perl:debian-etch:doctools:svn:git -t qemu-arm-sb

[sbox->:~]sb-conf se FREMANTLE_ARMEL_GCC472

[sbox-FREMANTLE_ARMEL_GCC472: ~] > sb-conf rs maemo-sdk-rootstrap_5.0_20.2010.36-2_armel.tgz

[sbox-FREMANTLE_ARMEL_GCC472: ~] > sb-conf in -edL

[sbox-FREMANTLE_ARMEL_GCC472: ~] > apt-get update
 [sbox-FREMANTLE_ARMEL_GCC472: ~] > fakeroot apt-get install maemo-sdk-debug

- Accept [http://tablets-dev.nokia.com/eula/index.php Maemo5 SDK EULA] and copy the URL. Add nokia-binaries repository URL to /etc/apt/sources.list

[sbox-FREMANTLE_ARMEL_GCC472: ~] >apt-get update
 [sbox-FREMANTLE_ARMEL_GCC472: ~] >fakeroot apt-get install nokia-binaries nokia-apps

[sbox-FREMANTLE_ARMEL_GCC472: ~] >rm -rf /targets/FREMANTLE_ARMEL_GCC472/opt
 [sbox-FREMANTLE_ARMEL_GCC472: ~] >mkdir /targets/FREMANTLE_ARMEL_GCC472/opt

- Download ScratchBox errata dependency provider package [http://maemo.merlin1991.at/cssu/develdebs/gcc-4.7.2_fremantle_armel/sb-thumb-errata-provider_0.1-1_armel.deb sb-thumb-errata-provider_0.1-1_armel.deb] and install it

dpkg -i sb-thumb-errata-provider_0.1-1_armel.deb

- Add CSSU-testing and CSSU-thumb repos to your /etc/apt/sources.list

echo "deb http://repository.maemo.org/community-testing/ fremantle free non-free" >> /etc/apt/sources.list
 echo "deb-src http://repository.maemo.org/community-testing/ fremantle free" >> /etc/apt/sources.list

echo "deb http://maemo.merlin1991.at/cssu/community-thumb/ fremantle free non-free" >> /etc/apt/sources.list
 echo "deb-src http://maemo.merlin1991.at/cssu/community-thumb/ fremantle free" >> /etc/apt/sources.list

Remove unneeded package maemo-core-debug
 apt-get remove maemo-core-debug

Upgrade your target to latest CSSU-thumb

[sbox-FREMANTLE_ARMEL_GCC472: ~] >apt-get update
 [sbox-FREMANTLE_ARMEL_GCC472: ~] >fakeroot apt-get upgrade

Download and install [http://maemo.merlin1991.at/cssu/develdebs/gcc-4.7.2_fremantle_armel/packages/libstdc%2b%2b6-dev_4.7.2-0%2bcssu0_armel.deb libstdc++6-dev_4.7.2-0+cssu0_armel.deb]
 dpkg -i libstdc++6-dev_4.7.2-0+cssu0_armel.deb

''It can complain about libstdc++6 on system is 4.2.1-4maemo13+0m5.''

apt-get -f install

''can fix that by installing the proper libstdc++6 afterwards.''

Create FREMANTLE_ARMEL_GCC472.environment in your /targets directory

echo "export DEB_BUILD_OPTIONS=maemo-launcher,thumb,vfp" > /targets/FREMANTLE_ARMEL_GCC472.environment

Your target should be ok at that point. Make sure to reenter the target, so updated FREMANTLE_ARMEL_GCC472.environment to take effect
