<title>How to Cross Build an LFS System</title>
|
|
|
|
<para>The LFS system will be built by using an already installed
|
|
UNIX-like system (such as Debian Linux or Mac OS X). This
|
|
existing UNIX-like 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 be able to access these
|
|
tools.</para>
|
|
|
|
<para>As an alternative to installing a separate distribution onto your
|
|
machine, you may wish to use <!-- the Linux From Scratch LiveCD or --> a LiveCD from a
|
|
commercial distribution. <!-- The LFS LiveCD works well as a host system,
|
|
providing all the tools you need to successfully follow the instructions in
|
|
this book. The LiveCD version is behind the current book, but is still useful
|
|
as a host for building the current book. The <quote>-nosrc</quote> or
|
|
<quote>-min</quote> editions of the LiveCD are the most appropriate for
|
|
building a current LFS system. For more information about the LFS LiveCD or
|
|
to download a copy, visit <ulink url="&livecd-root;"/>. --></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. This is the place
|
|
where the new LFS system will be compiled and installed. <xref
|
|
linkend="chapter-getting-materials"/> explains which packages and
|
|
patches need to 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 need be aware of before beginning 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 boots the
|
|
minimal Linux environment on the target machine and uses the previously
|
|
built tools to build the additional tools needed to build and test the
|
|
final system. Note that in the book the minimal Linux environment may be
|
|
referred as <quote>chroot environment</quote> only to keep the consistency
|
|
with the original LFS book.</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 LFS system is built.</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 set
|
|
up in <xref linkend="chapter-bootable"/>. <xref linkend="chapter-finalizing"/>
|
|
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.</para>
|
|
|
|
<para>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.</para>
