| 5 | <para>In this chapter we will compile and install a minimal
|
|---|
| 6 | Linux system. This system will contain just enough tools to be able
|
|---|
| 7 | to start constructing the final LFS system in the next chapter.</para>
|
|---|
| 8 |
|
|---|
| 9 | <para>The files compiled in this chapter will be installed under the
|
|---|
| 10 | <filename class="directory">$LFS/static</filename> directory,
|
|---|
| 11 | to keep them separate from the files installed in the next chapter.
|
|---|
| 12 | Since the packages compiled here are merely temporary, we don't want
|
|---|
| 13 | them to pollute the soon-to-be LFS system.</para>
|
|---|
| 14 |
|
|---|
| 15 | <para>The key to learning what makes a Linux system work is to know
|
|---|
| 16 | exactly what each package is used for, and why the user or the system
|
|---|
| 17 | needs it. For this purpose a short description of the content of each
|
|---|
| 18 | package is given right after the installation instructions.</para>
|
|---|
| 19 |
|
|---|
| 20 | <para>Several of the packages are patched before compilation, but only when
|
|---|
| 21 | the patch is needed to circumvent a problem. Often the patch is needed in
|
|---|
| 22 | both this and the next chapter, but sometimes in only one of them. So, don't
|
|---|
| 23 | worry when instructions for a downloaded patch seem to be missing.</para>
|
|---|
| 24 |
|
|---|
| 25 | <para>During the installation of most packages you will
|
|---|
| 26 | see all kinds of compiler warnings scroll by on your screen. These are
|
|---|
| 27 | normal and can be safely ignored. They are just what they say they are:
|
|---|
| 28 | warnings -- mostly about improper, but not illegal, use of the C or C++
|
|---|
| 29 | syntax. It's just that C standards have changed rather often and some
|
|---|
| 30 | packages still use the older standard, which is not really a problem.</para>
|
|---|
| 31 |
|
|---|
| 32 | <para>Before continuing, make sure the LFS environment variable is set up
|
|---|
| 33 | properly (if you decided to make use of it) by executing the following:</para>
|
|---|
| 34 |
|
|---|
| 35 | <para><screen><userinput>echo $LFS</userinput></screen></para>
|
|---|
| 36 |
|
|---|
| 37 | <para>Make sure the output shows the path to your LFS partition's mount
|
|---|
| 38 | point, which is <filename class="directory">/mnt/lfs</filename> if you
|
|---|
| 39 | followed our example.</para>
