[dd7f9df] | 13 | <para>This part is divided into three stages: first, building a cross
|
---|
| 14 | compiler and its associated libraries; second, using this cross toolchain
|
---|
[12fff1e] | 15 | to build several utilities in a way that isolates them from the host
|
---|
[dd7f9df] | 16 | distribution; and third, entering the chroot environment (which further improves
|
---|
| 17 | host isolation) and constructing the remaining tools needed to build the final
|
---|
[12fff1e] | 18 | system.</para>

[dd7f9df] | 20 | <important><para>This is where the real work of building a new system
|
---|
| 21 | begins. Be very careful to follow the instructions exactly as the book
|
---|
| 22 | shows them. You should try to understand what each command does,
|
---|
| 23 | and no matter how eager you are to finish your build, you should
|
---|
| 24 | refrain from blindly typing the commands as shown. Read the documentation when
|
---|
[12fff1e] | 25 | there is something you do not understand. Also, keep track of your typing
|
---|
[dd7f9df] | 26 | and of the output of commands, by using the <command>tee</command> utility
|
---|
| 27 | to send the terminal output to a file. This makes debugging easier
|
---|
| 28 | if something goes wrong.</para></important>
