SP Week 02 Assignment #2: Linux From Scratch 11.3 Ch. 1-5

Preparation (IMPORTANT!)

• CHECK if your GitHub Account = UserName = GroupName = Hostname.
• Check the output of script “01-Version-Check.sh”. Make sure, no errors! This includes “version-check.sh” of 2.2. Host System Requirements.
  • bash is the shell in use.
  • sh is a symbolic link to bash.
  • /usr/bin/awk is a symbolic link to gawk.
  • /usr/bin/yacc is a symbolic link to bison or a small script that executes bison.
• Check if you need more SWAP SPACE
• Check if you need to SHRINK and CLEAN your virtual files.

Follow “The Linux From Scratch version 11.3 Book” chapter 1-5

• The Linux From Scratch version 11.3 Book (mirror1) (mirror2) (mirror3)
  • Source code mirrors: (source mirror1) (source mirror2) (source mirror3)
• See also previous version LFS 11.2:
  • Kernotex’s YouTube LFS 11.2 PlayList
  • Kernotex’s Host Linux configuration for LFS Chapter 2.2 - “Host System Requirements”
  • The Kernotex’s Linux From Scratch (LFS) 11.2 Highlights Page (here)

Take Note: VirtualBox (+32 GB New Disk)

• “/mnt/lfs” does not exists.
  • See https://doit.vlsm.org/015.html
  • See chapters:
    • 2.4. Creating a New Partition
    • 2.5. Creating a File System on the Partition
    • 2.7. Mounting the New Partition
• Disk $LFS (VirtualBox)

echo $LFS
mkdir -pv $LFS
mkfs  -v -t ext4 /dev/sdb
mount -v -t ext4 /dev/sdb $LFS

• Append (edit) to /etc/fstab:

/dev/sdb   /mnt/lfs ext4   defaults      1     1

ℼ

Take Note: UTM (+32 GB New Disk)

• “/mnt/lfs” does not exists!
  • Read chapter 2
    • Your LFS disk is /dev/vdb
  • Account root:
    • Format and mount /dev/vdb
• Disk $LFS (UTM)

echo $LFS
mkdir -pv $LFS
mkfs  -v -t ext4 /dev/vdb
mount -v -t ext4 /dev/vdb $LFS

• Append (edit) to /etc/fstab:

/dev/vdb   /mnt/lfs ext4   defaults      1     1

• SYMLINK
  • For aarch64, create a symlink (root):

cd $LFS
ln -s lib lib64

• Chapter 5.5. Glibc-2.36
  • If you are using AArch64 (Apple Silicon), the example in the book does not work. You have to “trick” the building process. It might be OK since you do not cross-compile it to another architecture.
  • DO NOT FOLLOW THE COMPLETE CONFIGURATION OPTIONS in the book. Just do:

../configure        \
      --prefix=/usr 

ℼ

ALL: DO NOT SKIP

• 2.6. Setting The $LFS Variable
• 3.1. Introduction
  • Make sure files “wget-list-sysv” and “md5sums” are in $LFS/sources/:

root:~# ls -al $LFS/sources/{md5sums,wget-list-sysv}
-rw-r--r-- 1 root root 4709 Nov 14 04:36 /mnt/lfs/sources/md5sums
-rw-r--r-- 1 root root 5392 Sep  1 02:43 /mnt/lfs/sources/wget-list-sysv

• Download locations may not always be accessible. If unsuccessful, try:
  (source mirror1) (source mirror2) (source mirror3)
• Make sure when to use
  • your own account (e.g. “cbkadal” but you are not cbkadal!)
  • root account
  • lfs account
• Check your “LFS” and “MAKEFLAGS” environment for all accounts (e.g. “cbkadal”, “root”, “lfs”).

echo "LFS=$LFS MAKEFLAGS=$MAKEFLAGS"

ℼ

Binutils-2.40 - Pass 1: Standard Build Unit (SBU)

• See: 5.2.1. Installation of Cross Binutils

mkdir -v build
cd       build
time { ../configure --prefix=$LFS/tools \
             --with-sysroot=$LFS \
             --target=$LFS_TGT   \
             --disable-nls       \
             --disable-werror    && make && make install; }

Generate LFS Ch. 1-5 Report

• Last, after finishing chapter 5, run:

cd $HOME/myspwork/WEEK02/
bash 02-SP-WEEK02a.sh

ℼ

Result/Report

cd $HOME/SP_RESULT/W02/
ls -al
