<title>How to Build an LFS System</title>
|
|
|
|
<para>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 <quote>development</quote> option
|
|
during the distribution installation to include these
|
|
tools.</para>
|
|
|
|
<note><para>There are many ways to install a Linux distribution and
|
|
the defaults are usually not optimal for building an LFS system.
|
|
For suggestions on setting up a commercial distribution see:
|
|
<ulink url="&lfs-root;hints/downloads/files/partitioning-for-lfs.txt"/>.</para></note>
|
|
|
|
<para>As an alternative to installing a separate distribution on your
|
|
machine, you may wish to use a LiveCD from a commercial distribution.</para>
|
|
|
|
<!--
|
|
<note>
|
|
<para>The LFS LiveCD might not work on newer hardware configurations,
|
|
failing to boot or failing to detect some devices such as some SATA hard
|
|
drives.</para>

|
<para><xref linkend="chapter-partitioning"/> of this book describes how
|
|
to create a new Linux native partition and file system,
|
|
where the new LFS system will be compiled and installed. <xref
|
|
linkend="chapter-getting-materials"/> explains which packages and
|
|
patches must be downloaded to build an LFS system, and how to store
|
|
them on the new file system. <xref linkend="chapter-final-preps"/>
|
|
discusses the setup of an appropriate working environment. Please read
|
|
<xref linkend="chapter-final-preps"/> carefully as it explains several
|
|
important issues you should be aware of before you begin to
|
|
work your way through <xref linkend="chapter-cross-tools"/> and beyond.</para>
|
|
|
|
<para><xref linkend="chapter-cross-tools"/> 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.</para>
|
|
|
|
<para><xref linkend="chapter-temporary-tools"/> shows you how to
|
|
cross-compile basic utilities using the just built cross-toolchain.</para>
|
|
|
|
<para><xref linkend="chapter-chroot-temporary-tools"/> then enters a
|
|
"chroot" environment, where we use the new tools to build all
|
|
the rest of the tools needed to create the LFS system.</para>
|
|
|
|
<para>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 <xref linkend="ch-tools-toolchaintechnotes"/>.</para>
|
|
|
|
<para>In <xref linkend="chapter-building-system"/> the
|
|
full-blown 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 usual.</para>
|
|
|
|
<para>To finish the installation, the basic system configuration is set up in
|
|
<xref linkend="chapter-config"/>, and the kernel and boot loader are created
|
|
in <xref linkend="chapter-bootable"/>. <xref linkend="chapter-finalizing"/>
|
|
contains information on continuing the LFS experience beyond this book.
|
|
After the steps in this chapter have been implemented, the computer is
|
|
ready to boot into the new LFS system.</para>
|
|
|
|
<para>This is the process in a nutshell. Detailed information on each
|
|
step is presented in the following chapters.
|
|
Items that seem complicated now will be clarified, and everything will
|
|
fall into place as you commence your LFS adventure.</para>
