[5756284] | 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.
|
---|
[ef380b4] | 12 | Since the packages compiled here are merely temporary, we don't want
|
---|
| 13 | them to pollute the soon-to-be LFS system.</para>
|
---|
[5756284] | 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 |
|
---|
[5ebcbcc] | 20 | <para>Many of our packages must be patched before they can be compiled.
|
---|
| 21 | We only apply patches when and where they are needed. So, don't fret if
|
---|
[d0e55a6] | 22 | it seems like instructions for a patch are missing.</para>
|
---|
[5ebcbcc] | 23 |
|
---|
[5756284] | 24 | <para>During the installation of several packages you will probably
|
---|
| 25 | see all kinds of compiler warnings scroll by on your screen. These are
|
---|
| 26 | normal and can be safely ignored. They are just what they say they are:
|
---|
| 27 | warnings -- mostly about improper, but not illegal, use of the C or C++
|
---|
| 28 | syntax. It's just that C standards have changed rather often and some
|
---|
| 29 | packages still use the older standard, which is not really a problem.</para>
|
---|
| 30 |
|
---|
| 31 | <para>Before you start, make sure the LFS environment variable is set up
|
---|
[b822811] | 32 | properly if you decided to make use of it. Run the following:</para>
|
---|
| 33 |
|
---|
| 34 | <para><screen><userinput>echo $LFS</userinput></screen></para>
|
---|
| 35 |
|
---|
| 36 | <para>Check to make sure the output contains the correct directory to the LFS
|
---|
| 37 | partition's mount point (/mnt/lfs for example).</para>
