    1212
    13 <para>The primary target architectures of LFS are the AMD/Intel x86 (32-bit)
    14 and x86_64 (64-bit) CPUs.  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
     13<para>The primary target architectures of LFS-ARM are the ARM and ARM64 CPUs.
     14For other ARCHs refer to the main LFS book or CLFS as a historical reference.
     15To build a system that utilizes one of these CPUs, the main prerequisite, in
    1716addition to those on the next page, is an existing Linux system such as an
    1817earlier LFS installation, Ubuntu, Red Hat/Fedora, SuSE, or other distribution
    1918that 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>
    22 
    23 <para>For building LFS, the gain of building on a 64-bit system
    24 compared to a 32-bit system is minimal.
    25 For example, in a test build of LFS-9.1 on a Core i7-4790 CPU based system,
    26 using 4 cores, the following statistics were measured:</para>
    27 
    28 <screen><computeroutput>Architecture Build Time     Build Size
    29 32-bit       239.9 minutes  3.6 GB
    30 64-bit       233.2 minutes  4.4 GB</computeroutput></screen>
    31 
    32 <para>As you can see, on the same hardware, the 64-bit build is only 3% faster
    33 and is 22% larger than the 32-bit build. 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. That is, it supports 64-bit executables
    41 only. Building a <quote>multi-lib</quote> system requires compiling many
    42 applications twice, once for a 32-bit system and once for a 64-bit system.
    43 This is not directly supported in LFS because it would interfere with the
