Setup armv7h chroot under x86_64 host (Archlinux/Archlinuxarm biased)

Setup armv7h chroot under x86_64 host (Archlinux/Archlinuxarm biased)

Simple way to setup an arm chroot for building packages for your arm devices. This is an alternative to cross-compiling where you are limited to only linking against the libs in your toolchain.

Setup chroot-fs

You can store the chroot wherever you like. I choose to store it in a disk-image which I mount to my filesystem.

Archlinux ARM encrypted root

Intro

Just some FYI, to get started:

  • I'm using a 16 GB Sandisk SD card.
  • I have a model B Pi, 512 MB RAM (not really relevant, thought I'd mention it).
  • Monitor and keyboard connected to the Pi itself, for now.
  • Network working, internet access.
