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


GCC 4.7.2 does not produce thumb binaries by default, you should pass -mthumb if you want thumb resulting executables! without -mthumb it produces regular ARM ELFs


1. You need to have ScratchBox environment already set up.

2. Download 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

replace debian-etch with debian-squeeze if you use ScratchBox Hathor release

[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: ~] > dpkg -i /scratchbox/compilers/linaro-4.7-2012.07-fremantle-armv7a/packages/libfakeroot_1.14.4-0+sb1_armel.deb
[sbox-FREMANTLE_ARMEL_GCC472: ~] > apt-get update
[sbox-FREMANTLE_ARMEL_GCC472: ~] > fakeroot apt-get install maemo-sdk-debug

- Accept 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 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

IF ERROR When you now get an error the next step will show how to solve this, otherwise go to the step where libstdc++6 get installed.

Errors were encountered while processing: /var/cache/apt/archives/libssl0.9.8-dbg_0.9.8zh-1+maemo1+0m5+0cssu0_armel.deb

IF ERROR Solve it with otherwise go next step.

fakeroot apt-get -f install

IF ERROR Next errors will pop up.

Sub-process dpkg returned an error code (1)
Setting up libgtk2.0-0 (2:2.14.7-1maemo34+0cssu2+thumb0) ...
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
dpkg: error processing libgtk2.0-0 (--configure):
subprocess installed post-installation script returned error exit status 126

IF ERROR Solve it by editing following file:

vi /var/lib/dpkg/info/libgtk2.0-0.postinst

IF ERROR The command in the postinst script could not run, so we will comment out the following lines.

#if [ "$1" = configure ]; then
#   Regenerate theme caches which may need updating after gtk changes
#  if command -v hildon-theme-recache-all >/dev/null 2>&1; then
#    hildon-theme-recache-all
#  fi
#fi

IF ERROR There is another script which fails.

vi /var/lib/dpkg/info/libgtk2.0-bin.postinst

IF ERROR So we will comment out the following lines.

#/usr/sbin/update-gtk-immodules
#/usr/sbin/update-gdkpixbuf-loaders

IF ERROR Now fix it.

fakeroot apt-get -f install

Download and install 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.


Create FREMANTLE_ARMEL_GCC472.environment in your /targets directory

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

fakeroot apt-get -f install

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


Interesting new flags can be: -mfpu=neon -ftree-vectorize -fgraphite -lto

The compiler will give the following warning:

/scratchbox/compilers/linaro-4.7-2012.07-fremantle-armv7a/bin/../lib/gcc/arm-none-linux-gnueabi/4.7.2/../../../../arm-none-linux-gnueabi/bin/ld: BFD (GNU Binutils) 2.22 assertion fail ../../../sources/binutils-2.22/bfd/elf32-arm.c:11467

These warnings can be ignored. For some reason, the linker thinks that the object is hardfp, but as it is softfp the assertion fails.

ERROR ON UPGRADE A note I made.

fakeroot apt-get upgrade
fakeroot apt-get install libcurl3
fakeroot apt-get install ke-recv
fakeroot apt-get install obexd

ERROR ON UPGRADE To install this clock-ui we need another resource.

echo "deb http://maemo.muarf.org/apt-mirror/mirror/downloads.maemo.nokia.com/fremantle/ssu/mr0 ./" >> /etc/apt/sources.list
fakeroot apt-get install clock-ui
