On the other hand, the instructions in this book are 15 also known to work, with some modifications, with the Power PC and ARM CPUs. To 16 build a system that utilizes one of these CPUs, the main prerequisite, in 17 addition to those on the next page, is an existing Linux system such as an 18 earlier LFS installation, Ubuntu, Red Hat/Fedora, SuSE, or other distribution 19 that targets the architecture that you have. Also note that a 32-bit 20 distribution can be installed and used as a host system on a 64-bit AMD/Intel 21 computer.</para> 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.

If you plan to use LFS as a LAMP 34 server, or a firewall, a 32-bit CPU may be largely sufficient. On the other 35 hand, several packages in BLFS now need more than 4GB of RAM to be built 36 and/or to run, so that if you plan to use LFS as a desktop, the LFS authors 37 recommend building on a 64-bit system.</para> 38 39 <para>The default 64-bit build that results from LFS is considered a 40 <quote>pure</quote> 64-bit system.
