How to build

Introduction

• you should build natively, i.e. on an armhf Debian Wheezy or Jessie based SBC
• you should have approx. 10-20 GB storage on this SBC
• cross-compilation failed and we have no instructions
• ideally you should build in a sandbox, i.e. a chroot into a freshly debootstrapped subdirectory
• we set up ccache and a swapfile (needed if your machine has <= 512 MB RAM)

debootstrap the chroot sandbox

First, we debootstrap a fresh wheezy or jessie for armhf into some working directory (e.g. /debian-wheezy-armhf-qtmoko-build)

apt-get update && apt-get upgrade
apt-get install debootstrap psmisc bzip2 parted dosfstools
debootstrap --arch armhf wheezy /debian-wheezy-armhf-qtmoko-build http://ftp.us.debian.org/debian

mkdir -p "/debian-wheezy-armhf-qtmoko-build/proc" "/debian-wheezy-armhf-qtmoko-build/sys"
mount -t proc proc "/debian-wheezy-armhf-qtmoko-build/proc"
mount -t sysfs sys "/debian-wheezy-armhf-qtmoko-build/sys"
chroot /debian-wheezy-armhf-qtmoko-build
   # adjust the system to your needs (networking, tools, etc.)
   exit
umount /debian-wheezy-armhf-qtmoko-build/sys
umount /debian-wheezy-armhf-qtmoko-build/proc

Build from scratch

mkdir -p "/debian-wheezy-armhf-qtmoko-build/proc" "/debian-wheezy-armhf-qtmoko-build/sys"
mount -t proc proc "/debian-wheezy-armhf-qtmoko-build/proc"
mount -t sysfs sys "/debian-wheezy-armhf-qtmoko-build/sys"
chroot /debian-wheezy-armhf-qtmoko-build
