| 5 | In the following chapters we will install all the software that belongs to
|
---|
[72033583] | 6 | a basic Linux system. After a user is done with this chapter he has a
|
---|
[6370fa6] | 7 | fully working Linux system. The remaining chapters deal with setting up
|
---|
| 8 | networking, creating the boot scripts and adding an entry to lilo.conf so
|
---|
[72033583] | 9 | that the LFS system can be booted.

|
---|
| 13 | The software in this chapter will be linked statically. These programs
|
---|
[13dd793] | 14 | will be reinstalled in the next chapter and linked dynamically. The
|
---|
[6370fa6] | 15 | reason for the static version first is that there is a chance that our
|
---|
[72033583] | 16 | normal Linux system and the LFS system aren't using the same C
|
---|
[6370fa6] | 17 | Library versions. If the programs in the first part are linked against
|
---|
| 18 | an older C library version, those programs might not work well on the
|
---|
| 19 | LFS system.

|

| 23 | The key to learn what makes Linux tick is to know exactly what packages
|
---|
[72033583] | 24 | are used for and why a user or the system needs them. Descriptions
|
---|
[6370fa6] | 25 | of the package content are provided after the Installation subsection of each
|
---|
| 26 | package and in Appendix A as well.

|

| 30 | We're about to start with installing the first set of packages. These
|
---|
| 31 | packages will be, as previously explained, linked statically.

|
---|
[13dd793] | 35 | During the installation of various packages, the user will most likely see
|
---|
[72033583] | 36 | compiler warnings scrolling by on the screen. These are normal and can
|
---|
[6370fa6] | 37 | be safely ignored. They are just that, warnings (mostly about improper
|
---|
[13dd793] | 38 | use of the C or C++ syntax, but not illegal use. It's just that, often, C
|
---|
[6370fa6] | 39 | standards changed and packages still use the old standard which is not a
|
---|
| 40 | problem).

[72033583] | 44 | Before we start, it should be made sure the LFS environment variable was
|
---|
| 45 | setup
|
---|
| 46 | if it was planned to be used, by running the following command:
