Question Building CLFS with newest packages.


Hello everyone! I hope that I don't come off as rude by asking a question right away instead of introducing myself, but I'd really like to know if there is someone who tried building CLFS with newest packages (GCC 9.2.0, glibc 2.30, etc.). If so, are there any gotchas, things I should watch out for?

I would like to build a 32-bit CLFS on a 64-bit system, but the book seems to be a bit outdated compared to the main one (even the development version), and I'd like to download the latest tarballs. From what I see, some patches would probably no longer apply, like the one for GCC 7.1.0. Would it be a good idea to, for example, combine the CLFS commands, particularly the ./configure ones, with regular LFS ones (with some tweaking where needed)? Thank you in advance!

My experiences with regular LFS are:
With an LFS-8.2-tools/ch5 you can build up to at least gcc-9.2.0, glibc-2.28 and binutils 2.31.1.
Glibc 2.29 needs python3, if you add that to your tools-section you should be alright.
If you want to build 32-bit LFS, no need for CLFS, just use a live 32-bit environment.
OR create a chroot with an untarred tools tarball. Keith provides those for his LiveCD project.
I no longer build ch5 since I found his tarballs AND you can use newer gcc, glibc and binutils in the ch6 you are building.

Steps would be something like:
Download lfs-8.2/9.0-tools tarball, untar to /mnt/lfs/tools and chroot using the book at the beginning of ch6.
This should work with a 32-bit tarball, if it does not, just boot up a i686 livecd/USB.
