|

| 13 | <para>The target architectures of this LFS edition are ARM64 (sometimes
|
|---|
| 14 | called AArch64) CPUs. On the other hand, the instructions in this book may
|
|---|
| 15 | work on 32-bit ARM CPUs with some modifications. To build a system that
|
|---|
| 16 | utilizes one of these alternative CPUs, the main prerequisite, in
|
|---|
| 17 | addition to those on
|
|---|
| 18 | the next page, is an existing Linux system such as an earlier LFS
|
|---|
| 19 | installation, Ubuntu, Red Hat/Fedora, SuSE, or other distribution that
|
|---|
| 20 | targets the architecture that you have.</para>
|

| 21 |
|
|---|
| 22 | <para>The build results from this LFS edition is considered a
|
|---|
| 23 | <quote>pure</quote> 64-bit system. That is, it supports 64-bit executables
|
|---|
| 24 | only. Building a <quote>multi-lib</quote> system requires compiling many
|
|---|
| 25 | applications twice, once for a 32-bit system and once for a 64-bit system.
|
|---|
| 26 | This is not directly supported in LFS because it would interfere with the
|
|---|
| 27 | educational objective of providing the minimal instructions needed for a
|
|---|
| 28 | base Linux system. Some LFS/BLFS editors maintain a multilib fork
|
|---|
| 29 | of LFS, accessible at <ulink
|
|---|
| 30 | url="https://www.linuxfromscratch.org/~thomas/multilib/index.html"/>. But
|
|---|
| 31 | the multilib edition is for x86_64, and multilib is an advanced topic
|
|---|
| 32 | anyway.</para>
