| [ac6e9a3] | 13 | <para>The primary target architectures of this LFS edition are LoongArch
|
|---|
| 14 | CPUs.
|

| 15 | <!--On the other hand, the instructions in this book are
|
|---|
| 16 | also known to work, with some modifications, with the Power PC and ARM
|
|---|
| 17 | CPUs. -->
|
|---|
| 18 | To build a system that utilizes one of these CPUs, the main prerequisite, in
|
|---|
| [394dc3fc] | 19 | addition to those on the next page, is an existing Linux system such as an
|
|---|
| [ac6e9a3] | 20 | earlier LFS installation, Loong Arch Linux, CLFS for LoongArch, Gentoo,
|
|---|
| 21 | Slackware, or other distribution that targets LoongArch.</para>
|

| [c6d5b092] | 22 |
|
|---|
| [ac6e9a3] | 23 | <para>The build that results from this LFS edition is a
|
|---|
| 24 | <quote>pure</quote> lp64d system. That is, it supports executables with
|
|---|
| 25 | the lp64d ABI
|
|---|
| [394dc3fc] | 26 | only. Building a <quote>multi-lib</quote> system requires compiling many
|
|---|
| [ac6e9a3] | 27 | applications multiple times, once for each ABI to be supported.
|
|---|
| [394dc3fc] | 28 | This is not directly supported in LFS because it would interfere with the
|
|---|
| [7739ad3] | 29 | educational objective of providing the minimal instructions needed for a
|
|---|
| 30 | basic Linux system. Some of the LFS/BLFS editors maintain a multilib fork
|
|---|
| 31 | of LFS, accessible at <ulink
|
|---|
| 32 | url="https://www.linuxfromscratch.org/~thomas/multilib/index.html"/>. But
|
|---|
| [ac6e9a3] | 33 | the multilib edition is for x86_64, and multilib is an advanced topic
|
|---|
| 34 | anyway.</para>
