Using scratchbox2 and Ubuntu 11.10


Local machine environment:
- Ubuntu 11.10 64bits

Emulated environment:
- Debian Squeeze armel

Install in local machine:

sudo apt-get install scratchbox2 fakeroot
sudo apt-get install qemu-user qemu
sudo apt-get install gcc-arm-linux-gnueabi
sudo apt-get install cpp-4.4-arm-linux-gnueabi gcc-4.4-arm-linux-gnueabi gcc-4.4-arm-linux-gnueabi-base
sudo apt-get install cpp-4.5-arm-linux-gnueabi g++-4.5-arm-linux-gnueabi gcc-4.5-arm-linux-gnueabi

Init scratchbox configuration:

fakeroot debootstrap --variant=scratchbox --foreign --arch armel squeeze /path/root_fs http://ftp.br.debian.org/debian
sb2-init -n -c /usr/bin/qemu-arm MACHINE_NAME "arm-linux-gnueabi-gcc"

Install into emulated system:

apt-get install g++ rpm zlib1g-dev m4 bison libncurses5-dev gettext build-essential intltool libxml2-dev libtool

Compile outside the box:

cd source
sb2 ./configure
sb2 make -jN
sb2 make install DESTDIR=/path/root_fs

To change the crosscompiler toolchain install the script /usr/local/bin/switch_arm-linux-gnueabi.sh:

#!/bin/bash

if [ -z $1 ]; then
echo -e "\n Error: you need to define the arm-linux-gnueabi version"
echo -e " Usage: switch_arm-linux-gnueabi.sh \n"
exit
fi

if [ ! -f /usr/bin/arm-linux-gnueabi-cpp-$1 ]; then
echo -e "\n Error: arm-linux-gnueabi version $1 do not exist\n"
exit
fi
