• Zlib

This package contains compression and decompression routines used by some programs.

• Zstd

This package contains compression and decompression routines used by some programs. It provide high

compression ratios and a very wide range of compression / speed trade-offs.

Typography

To make things easier to follow, there are a few typographical conventions used throughout this book. This section

contains some examples of the typographical format found throughout Linux From Scratch.

./configure --prefix=/usr

This form of text is designed to be typed exactly as seen unless otherwise noted in the surrounding text. It is also used

in the explanation sections to identify which of the commands is being referenced.

In some cases, a logical line is extended to two or more physical lines with a backslash at the end of the line.

CC="gcc -B/usr/bin/" ../binutils-2.18/configure \

--prefix=/tools --disable-nls --disable-werror

Note that the backslash must be followed by an immediate return. Other whitespace characters like spaces or tab

characters will create incorrect results.

install-info: unknown option '--dir-file=/mnt/lfs/usr/info/dir'

This form of text (fixed-width text) shows screen output, usually as the result of commands issued. This format is also

used to show filenames, such as /etc/ld.so.conf.

Emphasis

This form of text is used for several purposes in the book. Its main purpose is to emphasize important points or items.

http://www.linuxfromscratch.org/

This format is used for hyperlinks both within the LFS community and to external pages. It includes HOWTOs,

download locations, and websites.

cat > $LFS/etc/group << "EOF"

root:x:0:

bin:x:1:

......

EOF

This format is used when creating configuration files. The first command tells the system to create the file $LFS/etc/

group from whatever is typed on the following lines until the sequence End Of File (EOF) is encountered. Therefore,

this entire section is generally typed as seen.

This format is used to encapsulate text that is not to be typed as seen or for copy-and-paste operations.

[OPTIONAL TEXT]

xvii

Linux From Scratch - Version 10.0

This format is used to encapsulate text that is optional.

passwd(5)

This format is used to refer to a specific manual (man) page. The number inside parentheses indicates a specific section

inside the manuals. For example, passwd has two man pages. Per LFS installation instructions, those two man pages

will be located at /usr/share/man/man1/passwd.1 and /usr/share/man/man5/passwd.5. When the

book uses passwd(5) it is specifically referring to /usr/share/man/man5/passwd.5. man passwd will print

the first man page it finds that matches “passwd”, which will be /usr/share/man/man1/passwd.1. For this

example, you will need to run man 5 passwd in order to read the page being specified. Note that most man pages do

not have duplicate page names in different sections. Therefore, man <program name> is generally sufficient.

Structure

This book is divided into the following parts.

Part I - Introduction

Part I explains a few important notes on how to proceed with the LFS installation. This section also provides meta-

information about the book.

Part II - Preparing for the Build

Part II describes how to prepare for the building process—making a partition, downloading the packages, and compiling

temporary tools.

Part III - Building the LFS Cross Toolchain and Temporary Tools

Part III provides instructions for building the tools needed for constructing the final LFS system.

Part IV - Building the LFS System

Part IV guides the reader through the building of the LFS system—compiling and installing all the packages one by

one, setting up the boot scripts, and installing the kernel. The resulting Linux system is the foundation on which other

software can be built to expand the system as desired. At the end of this book, there is an easy to use reference listing

all of the programs, libraries, and important files that have been installed.

Part V - Appendices

Part V provides information about the book itself including acronyms and terms, acknowledgments, package

dependencies, a listing of LFS boot scripts, licenses for the distribution of the book, and a comprehensive index of

packages, programs, libraries, and scripts.

Errata

The software used to create an LFS system is constantly being updated and enhanced. Security warnings and bug fixes

may become available after the LFS book has been released. To check whether the package versions or instructions in

this release of LFS need any modifications to accommodate security vulnerabilities or other bug fixes, please visit http://

www.linuxfromscratch.org/lfs/errata/10.0/ before proceeding with your build. You should note any changes shown and

apply them to the relevant section of the book as you progress with building the LFS system.

Linux From Scratch - Version 10.0

Chapter 1. Introduction

1.1. How to Build an LFS System

The LFS system will be built by using an already installed Linux distribution (such as Debian, OpenMandriva, Fedora,

or openSUSE). This existing Linux system (the host) will be used as a starting point to provide necessary programs,

including a compiler, linker, and shell, to build the new system. Select the “development” option during the distribution

installation to be able to access these tools.

As an alternative to installing a separate distribution onto your machine, you may wish to use a LiveCD from a

commercial distribution.

Chapter 2 of this book describes how to create a new Linux native partition and file system. This is the place where the

new LFS system will be compiled and installed. Chapter 3 explains which packages and patches need to be downloaded

to build an LFS system and how to store them on the new file system. Chapter 4 discusses the setup of an appropriate

working environment. Please read Chapter 4 carefully as it explains several important issues you need be aware of

before beginning to work your way through Chapter 5 and beyond.

Chapter 5, explains the installation of the initial tool chain, (binutils, gcc, and glibc) using cross compilation techniques

to isolate the new tools from the host system.

Chapter 6 shows you how to cross-compile basic utilities using the just built cross-toolchain.

Chapter 7 then enters a "chroot" environment and uses the previously built tools to build the additional tools needed

to build and test the final system.

This effort to isolate the new system from the host distribution may seem excessive. A full technical explanation as to

why this is done is provided in Toolchain Technical Notes.

In Chapter 8, The full LFS system is built. Another advantage provided by the chroot environment is that it allows you

to continue using the host system while LFS is being built. While waiting for package compilations to complete, you

can continue using your computer as normal.

To finish the installation, the basic system configuration is set up in Chapter 9, and the kernel and boot loader are set

up in Chapter 10. Chapter 11 contains information on continuing the LFS experience beyond this book. After the steps

in this book have been implemented, the computer will be ready to reboot into the new LFS system.

This is the process in a nutshell. Detailed information on each step is discussed in the following chapters and package

descriptions. Items that may seem complicated will be clarified, and everything will fall into place as you embark on

the LFS adventure.

1.2. What's new since the last release

In this version of LFS, there has been a major reorganization of the book using techniques that avoid changing the host

system and provides a more straight forward build process.

Below is a list of package updates made since the previous release of the book.

Upgraded to:

•

• Automake-1.16.2

• Bc 3.1.5

• Binutils-2.35

• Bison-3.7.1
