The above is a lot of work and requires a substantial long term
commitment of time and effort.
An alternative is to create a hint that takes a snapshot from a
current
version of the book(s) and documents what changes are needed that
differentiate the rpi from an x86_64 build.
Scott, as a Raspberry Pi enthusiast myself, I would love to see what
you came up with. I have completed LFS on Raspberry Pi before, thanks
to help from PiLFS (https://intestinate.com/pilfs/). I understand that
in post 8.0 versions of the LFS book, things are a lot easier for Pi
building. It would be awesome to include the extra notes in the
book(s) for everyone to use. I understand why splitting the book would
be a non-starter. In summary, this is a heartfelt vote in support of
including Pi-specific hints/notes in the LFS books, however minimizes
the burden to the great work the maintainers do for us all.
I will be posting my work to github, likely on or before Feb. I have a
couple of issues to work out and then do the build on my RPi2 all the
way thru from start to finish. I have a current build going on my
rpi4. If that goes well then I will build it on mu rp2 "build machine"
Incidentally, as slow as it is, building LFS directly on a real Pi
seems to be the least painful way. I tried to build for Pi in qemu,
hosted on Debian on Intel x64, and that was a total failure. For some
reason it got bogged down trying to build gcc. I gave up after it got
stuck for 8 days. I'm curious if anyone has gone down that road and
succeeded.
It takes me just over 36 hours to build LFS completely to a working
system. I build the kernel and firmware and add some scripts needed for
the clock. I will be building the broadcomm user utilities after I get
the LFS base build done. If all goes well I should be done next week.
