<?dbhtml filename="introduction.html" dir="chapter05"?>

|
|
|
<para>In this chapter we will compile and install a minimal
|
|
Linux system. This system will contain just enough tools to be able
|
|
to start constructing the final LFS system in the next chapter.</para>
|
|
|
|
<para>The files compiled in this chapter will be installed under the
|
|
<filename class="directory">$LFS/static</filename> directory,
|
|
to keep them separate from the files installed in the next chapter.
|
|
Since the packages compiled here are merely temporary, we don't want
|
|
them to pollute the soon-to-be LFS system.</para>
|
|
|
|
<para>The key to learning what makes a Linux system work is to know
|
|
exactly what each package is used for, and why the user or the system
|
|
needs it. For this purpose a short description of the content of each
|
|
package is given right after the installation instructions.</para>
|
|
|
|
<para>Many of our packages must be patched before they can be compiled.
|
|
We only apply patches when and where they are needed. So, don't fret if
|
|
it seems like instructions for a patch are missing.</para>
|
|
|
|
<para>During the installation of several packages you will probably
|
|
see all kinds of compiler warnings scroll by on your screen. These are
|
|
normal and can be safely ignored. They are just what they say they are:
|
|
warnings -- mostly about improper, but not illegal, use of the C or C++
|
|
syntax. It's just that C standards have changed rather often and some
|
|
packages still use the older standard, which is not really a problem.</para>
|
|
|
|
<para>Before you start, make sure the LFS environment variable is set up
|
|
properly if you decided to make use of it. Run the following:</para>
|
|
|
|
<para><screen><userinput>echo $LFS</userinput></screen></para>
|
|
|
|
<para>Check to make sure the output contains the correct directory to the LFS
|
|
partition's mount point (/mnt/lfs for example).</para>
