OS Week 08 Assignment #3: Linux From Scratch 12.1 Ch. 1-5

Preparation (IMPORTANT!)

Check file system /mnt/lfs

df | grep lfs

ℼ

If there is no “/mnt/lfs”, see here.

ℼ

Follow “The Linux From Scratch version 12.1 Book” chapter 1-5

• VirtualBox (AMD64)
  • The Linux From Scratch version 12.1 Book (mirror1) (mirror2) (mirror3)
• UTM/M1 (ARM64/AARCH64)
  • The Linux From Scratch ARM64/AARCH64 Book
  • COMPARE
    LFS ARM64/AARCH64 is not an official version (KW) and changes frequently. Therefore, it is recommended to use a package similar to the official version of LFS 12.1 (ORI). Because of this, the instructions for the KW version packages often differ from those for the ORI. Since it uses the ORI package, it must sometimes be compiled using the ORI method. Please be careful, especially when working on chapter 8 and explicitly compiling GCC (chapter 8.28).
    • VISIT https://yforku.github.io/os241/LFS/.
• Source Code Mirrors: (source mirror1) (source mirror2) (source mirror3)
• Kernotex’s YouTube LFS 12.1 PlayList
  • Kernotex’s Host Linux configuration for LFS Chapter 2.2 - “Host System Requirements”
  • Kernotex’s LFS in VirtualBox

Take Note: SKIP Ch 2.4, 2.5, 2.7

Because “/mnt/lfs/” already exists!

• Chapter 2.4. Creating a New Partition
• Chapter 2.5. Creating a File System on the Partition
• Chapter 2.7. Mounting the New Partition

ℼ

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

• Chapter 2.6. Setting The $LFS Variable
• Chapter 3.1. Introduction

These are ALL SCRIPTS of chapter 3.1. Make sure no ERRORS!

• See also os1:///home/zzyLFS/

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 5130 Sep  1 23:00 /mnt/lfs/sources/md5sums
# -rw-r--r-- 1 root root 5932 Sep  1 23:00 /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/
• 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    && make && make install; }
echo "I am $(whoami); using $(uname -r) $(df $LFS|tail -1|awk '{print $1,int($2/1000000)"G"}')" 
echo "LFS=\"$LFS\" ARCH=$(arch) NPROC=$(nproc) MAKEFLAGS=$MAKEFLAGS"

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
