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

Some other facts about 64-bit systems need to be added here. When compared to a 32-bit system, the sizes of executable programs are slightly larger and the execution speeds are only slightly faster. For example, in a test build of LFS-6.5 on a Core2Duo CPU based system, the following statistics were measured:
 +
 
 +
Architecture Build Time    Build Size
 +
32-bit      198.5 minutes  648 MB
 +
64-bit      190.6 minutes  709 MB
 +
 
 +
As you can see, the 64-bit build is only 4% faster and is 9% larger than the 32-bit build. The gain from going to a 64-bit system is relatively minimal. Of course, if you have more than 4GB of RAM or want to manipulate data that exceeds 4GB, the advantages of a 64-bit system are substantial.

Nagu võid näha on 64-bitise süsteemi kompileerimine 34-bitisest 4% kiirem ja 9% suurem. Ehk võit 64-bitise süsteemi kasutamisel on minimaalne. Muidugi, kui sul on rohkem mälu kui 4GB, või soovid manipuleerida andmetega mis ületavad 4GB on 64-bitise süsteemi eelised vaieldamatud.

The default 64-bit build that results from LFS is considered a "pure" 64-bit system. That is, it supports 64-bit executables only. Building a "multi-lib" system requires compiling many applications twice, once for a 32-bit system and once for a 64-bit system. This is not directly supported in LFS because it would interfere with the educational objective of providing the instructions needed for a straightforward base Linux system. You can refer to the Cross Linux From Scratch project for this advanced topic.

There is one last comment about 64-bit systems. There are some packages that cannot currently be built in a "pure" 64-bit system or require specialized build instructions.

This includes some Xorg drivers from Beyond Linux From Scratch (BLFS). Many of these problems can be worked around, but may require some specialized procedures or patches.

The primary target architecture of LFS is the 32-bit Intel CPU. If you have not built an LFS system before, you should probably start with that target. The 32-bit architecture is the most widely supported Linux system and is most compatible with both open source and proprietary software.

Primaarne LFS sihtarhidektuur on 32-bitine Inteli CPU. Tegemist on arhidektuuriga millest oleks alustada juhul kui sa ei ole varem LFS süsteemiga kokku puutunud 32-bitine arhidektuur on ühtlasi kõige laiemalt linuxi poolt toetatud ja rohkem ühilduv vabavara ja proprietary tarkvara poolt.

To build a system that utilizes one of these CPUs, the main prerequisite, in addition to those on the next few pages, is an existing Linux system such as an earlier LFS installation, Ubuntu, Red Hat/Fedora, SuSE, or other distribution that targets the architecture that you have. Also note that a 32-bit distribution can be installed and used as a host system on a 64-bit AMD/Intel computer.

Teisest küljest, selle raamatu instruktsioonid on teadaolevat mõnede modifikatsioonidega toimivad ka nii PowerPC kui 64-bitiste AMD/Inteli protsessoritega. Selleks, et ehitada süsteem mis kasutab ühte neist protsessoritest.

Veel mõned faktid 64-bitisest süsteemist. Võrrelduna 32-bitise süsteemiga, käivitavate programmifailide suurused on silmnähtavalt mahukamad ja nende käivitamise kiirus on vaid õrnalt suurem. Näiteks tehes LFSD-6.5 testbuildi Core2Duo protsessoril mõõdeti järgnevad tulemused.
