CSSU-thumb toolchain setup (gcc4.7.2-linaro)

<p>92.130.88.10: </p>
<hr />
<div>This document describes how to setup the CSSU-thumb toolchain (gcc4.7.2-linaro) in scratchbox.<br />
<br />
<br />
''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''<br />
<br />
<br />
1. You need to have [http://wiki.maemo.org/Documentation/Maemo_5_Final_SDK_Installation ScratchBox] environment already set up.<br />
<br />
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)<br />
tar xvf linaro-4.7-2012.07-fremantle-armv7a.tar.bz2<br />
<br />
3. Create new ScratchBox target FREMANTLE_ARMEL_GCC472<br />
<br />
- Login to ScratchBox <br />
<br />
$ /scratchbox/login<br />
<br />
- Create new ScratchBox target<br />
<br />
[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<br />
<br />
replace debian-etch with debian-squeeze if you use ScratchBox Hathor release <br />
<br />
[sbox->:~]sb-conf se FREMANTLE_ARMEL_GCC472<br />
<br />
[sbox-FREMANTLE_ARMEL_GCC472: ~] > sb-conf rs maemo-sdk-rootstrap_5.0_20.2010.36-2_armel.tgz<br />
<br />
[sbox-FREMANTLE_ARMEL_GCC472: ~] > sb-conf in -edL<br />
<br />
[sbox-FREMANTLE_ARMEL_GCC472: ~] > dpkg -i /scratchbox/compilers/linaro-4.7-2012.07-fremantle-armv7a/packages/libfakeroot_1.14.4-0+sb1_armel.deb<br />
<br />
[sbox-FREMANTLE_ARMEL_GCC472: ~] > apt-get update<br />
[sbox-FREMANTLE_ARMEL_GCC472: ~] > fakeroot apt-get install maemo-sdk-debug<br />
<br />
- 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 <br />
<br />
[sbox-FREMANTLE_ARMEL_GCC472: ~] >apt-get update<br />
[sbox-FREMANTLE_ARMEL_GCC472: ~] >fakeroot apt-get install nokia-binaries nokia-apps<br />
<br />
[sbox-FREMANTLE_ARMEL_GCC472: ~] >rm -rf /targets/FREMANTLE_ARMEL_GCC472/opt<br />
[sbox-FREMANTLE_ARMEL_GCC472: ~] >mkdir /targets/FREMANTLE_ARMEL_GCC472/opt<br />
<br />
- 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<br />
<br />
dpkg -i sb-thumb-errata-provider_0.1-1_armel.deb<br />
<br />
- Add CSSU-testing and CSSU-thumb repos to your /etc/apt/sources.list<br />
<br />
echo "deb http://repository.maemo.org/community-testing/ fremantle free non-free" >> /etc/apt/sources.list<br />
echo "deb-src http://repository.maemo.org/community-testing/ fremantle free" >> /etc/apt/sources.list<br />
<br />
echo "deb http://maemo.merlin1991.at/cssu/community-thumb/ fremantle free non-free" >> /etc/apt/sources.list<br />
echo "deb-src http://maemo.merlin1991.at/cssu/community-thumb/ fremantle free" >> /etc/apt/sources.list<br />
<br />
Remove unneeded package maemo-core-debug<br />
apt-get remove maemo-core-debug<br />
<br />
Upgrade your target to latest CSSU-thumb<br />
<br />
[sbox-FREMANTLE_ARMEL_GCC472: ~] >apt-get update<br />
[sbox-FREMANTLE_ARMEL_GCC472: ~] >fakeroot apt-get upgrade<br />
<br />
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]<br />
dpkg -i libstdc++6-dev_4.7.2-0+cssu0_armel.deb<br />
<br />
''It can complain about libstdc++6 on system is 4.2.1-4maemo13+0m5.''<br />
<br />
<br />
Create FREMANTLE_ARMEL_GCC472.environment in your /targets directory<br />
<br />
echo "export DEB_BUILD_OPTIONS=maemo-launcher,thumb,vfp" > /targets/FREMANTLE_ARMEL_GCC472.environment<br />
echo "export PIXMAN_DISABLE=arm-neon" >> /targets/FREMANTLE_ARMEL_GCC472.environment<br />
<br />
Your target should be ok at that point. Make sure to reenter the target, so updated FREMANTLE_ARMEL_GCC472.environment to take effect<br />
<br />
fakeroot apt-get -f install<br />
<br />
''can fix that by installing the proper libstdc++6 afterwards.''<br />
<br />
<br />
Interesting new flags can be: <nowiki>-mfpu=neon -ftree-vectorize -fgraphite -lto</nowiki><br />
<br />
The compiler will give the following warning:<br />
/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<br />
These warnings can be ignored. For some reason, the linker thinks that the object is hardfp, but as it is softfp the assertion fails.<br />
