[Clfs-dev] Matching up CLFS snapshot versions with LFS/BLFS releases

[Kevin Buckley]

I just posted the following into the LFS-dev list, adding in a
couple email addres that i though would go to the listed author
of the CLFS book, but two of the three have bounced so I
thought to post here as well.

Hi again.

been looking to add a Xen environment on top of my LFS/BLFS 8.0
build (very little BLFS if truth be told) and.although I'm not sure I need
the 32-bit parts of Xen, I have seen a couple of references to them, as
the build fails, for example

...

compilation terminated.


With that in mind, I've cloned the CLFS Git repo, where I note that
the main "toolchains" are

Latest Release 3.0.0
   - CLFS-3.0.0-SYSVINIT-x86_64.html
      - Glibc-2.19
      - Binutils-2.24
      - GCC-4.8.3

Current snapshot
   - CLFS-SYSVINIT-TRUNK-SYSVINIT-20170702/x86_64/
      - Glibc-2.25
      - Binutils-2.28
      - GCC-7.1.0

but that the main LFS/BLFS has a toolchain comprising

LFS-8.0
   - Glibc-2.25
   - Binutils-2.27
   - GCC-6.3.0

so somewhere in between the two easily identifiable CLFS revisions.

The CLFS Git repo's tags appear to be

clfs-1.0.0
clfs-1.0.0-rc1
clfs-1.0.0-rc2
clfs-1.0.0-rc3
clfs-1.0.0-rc4
clfs-1.0.0-rc5
clfs-1.0.0-rc6
clfs-1.1.0
clfs-1.1.0-rc1
clfs-1.1.0-rc2
clfs-1.1.0-rc3
clfs-1.2.0
clfs-2.0.0
clfs-2.0.0-rc1
clfs-2.1.0
clfs-3.0.0-rc1-systemd
clfs-3.0.0-rc1-sysvinit
clfs-3.0.0-systemd
clfs-3.0.0-sysvinit


so nothing that suggests any direct correspondence with LFS/BLFS
release numbers, so, my questions are:

1) Are the any known CLFS "commits"  that can be associated with the
     "mainline"  LFS/BLFS releases
    Or do I just have to wade through them and find one that matches.

2) If I already have a 64-bit LFS/BLFS 8.0 system, can I just retro-fit
     the 32-bit libs (so as to give what I think is then a MultiLib system)
     using the 64-bit (Chapter 6) toolchain ?
    Or do I have to go and build a MultiLib compiler in the "Chapter 5"
     stage
