<title>What is Multilib?</title>
|
|
|
|
<para>
|
|
Multilib is essentially the ability to at least execute software
|
|
that was built for another architecture different from your own.
|
|
For example, and most common: the user has a x86_64 CPU that is
|
|
wanting to execute software built to run on a x86 CPU. To better
|
|
establish terms, x86_64 is 64-bit and amd64, whereas x86 is
|
|
32-bit and ix86 where <option>x</option> can vary from 3 to 6
|
|
usually.

<title>How Does it Work?</title>
|
|
|
|
<para>
|
|
Multilib can be achieved firstmost by having the hardware
|
|
capable of x86 emulation, then having libraries built for x86.
|
|
We will get into how to compile x86 libraries and software and
|
|
their execution later, but know the general process for LFS
|
|
and BLFS is to almost always compile software and that's what
|
|
we'll be doing.

<para>
|
|
It is worth nothing that when covering multilib, we mean
|
|
emulation of 32-bit software on a 64-bit CPU and this
|
|
is the case for most users nowadays, but the future is heading
|
|
towards ARM64 slowly. We will not be covering ARM at this time.

<title>Am I Capable of Multilib?</title>

<para>
|
|
If you are on a 32-bit CPU, you are not capable of multilib.
|
|
If you are on a 64-bit CPU, and are capable of 32-bit emulation,
|
|
then you are capable of multilib.

Run <command>uname -m</command> to find out if you are on a

capable CPU.
