OS Week 08 Assignment #3: Linux From Scratch 12.2 Ch. 1-5

Preparation (IMPORTANT!)

Check file system /mnt/lfs

df | grep lfs

ℼ

If there is no “/mnt/lfs”, see here.

ℼ

Check some environments for the ROOT account

# SUPERUSER (ROOT)
echo "LFS=\"$LFS $(df $LFS|tail -1|awk '{print $1,int($2/1000000)"G"}')\" ARCH=$(arch) NPROC=$(nproc)"

ℼ

LFS should be mounted on /mnt/lfs
LFS size should be 32GB

ℼ

Follow “The Linux From Scratch version 12.2 Book” chapter 1-5

VirtualBox (AMD64)
- LFS 12.2 ORI (alt1) (alt2) (alt3)
UTM/M1 (ARM64/AARCH64)
- LFS 12.2 CBK — This version was adjusted to be close to the AMD ORI 12.2 version.
Source Code Mirrors: (source mirror1) (source mirror2) (source mirror3)
Kernotex’s YouTube LFS 12.2 PlayList
- Kernotex’s Host Linux configuration for LFS Chapter 2.2 - “Host System Requirements”
- Kernotex’s LFS in VirtualBox

ℼ

Take Note: SKIP Ch 2.4, 2.5, 2.7

Because “/mnt/lfs/” already exists!

ℼ

Take Note: DO NOT SKIP Ch 2.6, 3.1 (ROOT)

Chapter 2.6. Setting The $LFS Variable (ARM64).
Chapter 3.1. Introduction (ARM64). Use this SCRIPT for chapter 3.1. Make sure no ERRORS!
- Fetching all the necessary LFS packages (see also os1:///home/zzyLFS/).
- Use this SCRIPT for chapter 3.1. Make sure no ERRORS!

# This is for both VirtualBox and UTM

fi

ℼ
Make sure files “wget-list-sysv” and “md5sums” are in $LFS/sources/

ls -al $LFS/sources/{md5sums,wget-list-sysv}
# -rw-r--r-- 1 root root 5110 Sep  1 02:27 /mnt/lfs/sources/md5sums
# -rw-r--r-- 1 root root 5957 Sep  1 02:27 /mnt/lfs/sources/wget-list-sysv

Download locations may not always be accessible. If unsuccessful, try:
(source mirror1) (source mirror2) (source mirror3)
- See also os1:///home/zzyLFS/
After downloading the packages (chapter 3.1), continue to Chapter 4, and so on.
Make sure you have three accounts:
- your own account (e.g. cbkadal but you are not cbkadal!)
- root account
- lfs account
Make sure when to use:
- your own account (e.g. “cbkadal”)
- root account
- lfs account

Binutils-2.41 - Pass 1: Standard Build Unit (SBU)

Chapter 5.2.1. Installation of Cross Binutils (lfs)

Check your “LFS”, “ARCH”, “NPROC”, and “MAKEFLAGS” environment for all accounts (e.g. “cbkadal”, “root”, “lfs”).

mkdir -v build
cd       build
time { ../configure --prefix=$LFS/tools \
             --with-sysroot=$LFS \
             --target=$LFS_TGT   \
             --disable-nls       \
             --enable-gprofng=no \
             --disable-werror    \
             --enable-new-dtags  \
             --enable-default-hash-style=gnu && make && make install; }
echo "ZCZC I am $(whoami)@$(hostname) using $(uname -r) $(df $LFS|tail -1|awk '{print $1,int($2/1000000)"G"}')" 
echo "LFS=\"$LFS\" ARCH=$(arch) NPROC=$(nproc) MAKEFLAGS=$MAKEFLAGS"

ℼ

Generate LFS Chapters 1-5 Report

Last, after finishing chapter 5, run (cbkadal):

export LFS="/mnt/lfs/"
cd $HOME/mywork/WEEK08/
bash 08_WEEK08.sh

ℼ

Result/Report

(cbkadal):

cd $HOME/RESULT/W08/
ls -al
