15 Chapter 4, Steam part 1: How to build GLFS # 443351 on 32-Bit

A few dependencies for Steam are built including a tweak to the kernel.

In this series of videos I show Gaming Linux From Scratch (GLFS) revision # 443351 being installed on a 32-Bit version of Linux From Scratch 12.3.

The host operating, Linux From Scratch is a standard v12.3 build with some extra tools to allow remote access and make it easier to build GLFS right from the very beginning. Most, if not all of these tools are rebuilt as part of GLFS. The complete build process is captured throughout this series.

I decided to go ahead and do this as the GLFS instructions indicated that it would be possible to build GLFS on a 32 bit installation. Therefore I was interested to see how well it would work and sourced one of the last 'pure' 32 bit Intel x86 CPUs released. Although higher clocked models were released, the time saved using one of these would have been minimal in return for more heat generated and energy consumed.

Specifically, I used a Pentium 4 with Northwood C (aka Pentium HT) architecture. Northwood C Pentium 4s are special for two significant historical reasons:

1. It is the last time a CPU with 32 bit (aka i686 or x86) architecture was available across all Intel CPUs within the range.
2. It is the first time that all models of Intel desktop CPUs had Hyper Threading across the whole range.

To re-iterate: Only the top of the range 3.06 GHz model of the previous Pentium 4 Northwood B iteration had Hyper Threading (the very first time HT appeared in a desktop CPU). The next generation of CPUs after Northwood C (called Prescott) were based on either LGA 478 or LGA 775 sockets depending on the model and certain LGA 775-based CPUs were 64 bit capable.

In using a CPU that is over 20 years old for this project, it's perhaps not surprising that the complete build takes many CPU hours.

As with the standard LFS build, all packages used in GLFS are freely available. They are open source and compiled from source except the following:

1. Steam
2. Factorio (used for demonstrations and not part of GLFS)
