The differenc between CLFS,BLFS ALFS and LFS

I have seen the LFS web site.But I can't find the differences between CLFS ALFS BLFS and the LFS.
I have installed LFS successfully ever.
I can't understand why exists so many differences LFS project.

(... oh come on)

ALFS - AUTOMATED Linux From Scratch: Same as LFS with less typing.

CLFS - CROSS Linux From Scratch: A useful exercise in cross compiling, also needed for anyone wanting LFS on a 64 bit arch.

BLFS - BEYOND Linux From Scratch: Instructions for building software not included in a base LFS system eg. Xorg.

Congrats on completing LFS.

Well
CLFS is A useful exercise in cross compiling
LFS also is a useful exercise in cross compiling
Why we need clfs?

Personally I wouldn't call LFS true cross-compiling. To me cross-compiling always meant building binaries on one system that will work on another completely different architecture (also counting a P4 compiling for an older P2). In LFS the host system is usually the target system. It comes down to how you want to define cross-compile.

CLFS started because LFS was limited (and still is) to x86 only. From CLFS:

Quote:

The one "flaw" in LFS is that it has always been based on an x86 class processor. With the advent of the Athlon 64 and Intel EM64T processors, the x86-only LFS is no longer ideal. Throughout this time, Ryan Oliver developed and documented a process by which you could build Linux for any system and from any system, by use of cross-compilation techniques. Thus, the Cross LFS project was born.

To put it to extremes: with CLFS it is possible (in theory) to compile a system on a P4 for an alfa processor, with lfs this can not be done.
I've used LFS multiple times. I haven't used CLFS yet, but my advice would be to start with LFS as the proper guide says

Nothing about "in theory" here.
The CLFS goal is to compile linux from anything for anything.
We have mostly succeded... still issues with the kernel for sun4m and m68k-mac (though should work for m68k atari/amiga but not tested) still need to fix ADB on mac m68k and sun4m hypersparc is broken, sun4m supersparc is fscked for SMP...

Cross-LFS will provide you with a fully functional userspace for most architectures, kernel side though can be a bit of fun
