#!/bin/bash
#
# This script is the second stage in bootstrapping a Slackware build
# to a new platform or architecture. Running stage1.sh with no arguments
# builds a cross-development environment, then cross-builds a minimal
# rootfs. Once you have this minimal rootfs booted (or chroot'd), run
# stage2.sh (this script) in that rootfs to build the rest of the
# bootstrap packages.
#
# This script assumes that all the needed sources are installed in
# $SLACKSOURCE (below) by stage1.sh. Each build installs into /usr.
#
# You may pass a single package name on the command line to rebuild
# just that one package.
#
# The master upstream for this script is:
# http://fedorapeople.org/cgit/djdelorie/public_git/bootstrap.git/
#
# ------------------------------------------------------------
#
# --- NOTES FOR PACKAGE PORTING ---
#
# This script is stage TWO of a bootstrap process. EVERYTHING that
# this script uses MUST be provided by the stage ONE script -
# filesystem, utilities, sources, etc. Please keep this in mind when
# editing this script - anything you do manually to "prepare" for your
# build, will NOT be reproducible.
#
# Please make sure your package is not in either stage1 or stage2, and
# that nobody else is already working on your package, before
# starting. Grep is your friend. See the wiki page for details.
#
# There are FOUR places you must edit when adding packages to the
# bootstrap build:
#
# 1. Add a clause at the end of this script to actually build your
# package.
#
# 2. Add your package to the "" case at the beginning of the package
# list, about a page down from these comments. Put in the order in
# which it needs to build based on its dependencies.
#
# 3. Add your package source to the list at the end of the stage1 script
# so that your sources are available in the bootstrap rootfs.
#
# 4. Update the Fedora/ARM bootstrap wiki page.
#
# If you attempt to add a package and discover some unsatisfied build
# dependency, add a clause for it here that documents the dependency
# and exits with a non-zero code. In that case, do not add your
# package to the "" case.
