Linux From Scratch, Book 8.1
 Notes On Build Steps and Process
2017 Autumn and Winter



^ Overview


This wiki article contains notes on build steps and process detailed in Linux From Scratch book 8.1. This work spurred by Ted's finding that Robert Landley's Aboriginal Linux project is defunct and no longer developed as of spring or summer 2017. Robert had gotten a compressed and simplified Linux build framework down to seven packages, which could build all the necessary tools including themselves, to create a base Linux system. On this base system then a user could further tailor and develop custom software to fit a wide variety of use cases, including embedded system uses and cross-compiling based system uses.

In absence of a supported Aboriginal Linux, Ted here working through 'Linux From Scratch' to build a system crossed-compiled for the ARM architecture, with goal of buildng complete working Linux OS to run on RaspberryPi development boards. At same time Ted looking to build minimal system and tool chain, offering environment in which to compile and to cross-compile C and C++ programs.



Notes here begin with some useful, initially found links to LFS home page of Gerard Beekman et al:



Linux From Scratch project observes Linux Standard Base (LSB) requirements. These requirements include,


Cross-compiling Linux system from scratch . . .


Linux from Scratch for RaspberryPi target system . . .


Some Linux programs and utilities, services worth studying further, for better understanding of system and networking:

  • grub, EFI and UEFI
  • iproute, routef and routel, IPV4 routine tables
  • util-linux-2.30.1 . . . chapter 6.66, lots of utilities here!



^ First mount and build steps

- 2017-90-18 MON -

LFS book release 8.1, chapter 2.4 talks about typical and "convenience" partitions which are often or sometimes created for Unix and Linux systems. Ted's notebook of LFS work past two weeks not on hand, but going from memory and cfdisk partition list which lacks labels and mount points, here are the partitions Ted created first time stepping through chapter 2:


Figure x - initial LFS 8.1 partitioning choices, using 8GB root directory:

Started working through LFS 8.1 book using above partitions but found __libc or glibc build step__ required beyond 8GB space during a testing phase, and so __changed the partitions__ to create a larger root partition as shown in next figure:

Per chapter 2.4 comments on convenience partitions, Ted not creating a partition for either /usr nor /tmp. Ted creating /opt for software which falls outside of Debian and Ubuntu package lists, such as LPCXpresso and LTSpice.

Working through LFS stable release book or instructions, at end of chapter two page titled chapter 2.7 LFS book calls for first mount of newly created system-to-be partition. Ted using ext4 type journaled file system. Somewhere in or about chapter five, further mounts of other file systems of the new system are needed. Here are key mounting steps needed to proceed with work at end of LFS book 8.1 chapter 2 and int chapter 3 and onward. These mount steps depend that environment variable $LFS set to /mnt/lfs . . . 



    $ # From LFS 8.1 chapter 2.7, mounting the new file system:

    $ sudo mount -v -t ext4 /dev/sdb5 /mnt/lfs


    $ # From LFS 8.1 chapter 6.2, preparing virtual kernel file systems:

    $ sudo mount -v --bind /dev $LFS/dev
    $ sudo mount -vt proc proc $LFS/proc
    $ sudo mount -vt sysfs sysfs $LFS/sys
    $ sudo mount -vt tmpfs tmpfs $LFS/run


Ted noting specific mount steps as root partition at 7.7GB too small to permit chapter 6 builds. Ted learning parted disk partitioning utility in order to resize /dev/sdb5 root partition of 2017 September LFS project build. There appears to be some good notes on using a tool named resize2fs at the AskUbuntu forum page https://askubuntu.com/questions/390769/how-do-i-resize-partitions-using-command-line-without-using-a-gui-on-a-server. But neither parted for resize2fs alone were the answer, Ted uses cfdisk, e2fsck and resize2fs to achieve a partition and corresponding file system size increase.

After building first package binutils-2.29 the directory /tools holds directories and files in the following command line snippet of figure x. Bin-utils 2p29 took about 5 mins 30 seconds to build:

Back in September / early October Ted set aside work on LFS book 8.1, at the end of chapter 6 and just a bit into chapter 7. Picking up the work again, there are some key steps for mounting partitions and their respective LFS 8.1 file systems detailed in chapter 6 sections 2.2 and 2.3. The table of LFS chapter 6 contents is useful also, and given here for easier reference:



^ chapter 6.2 - preparing virtual kernel file systems


Specific mount invocations mentioned in chapter 6.2. From section 6.2.2 the first mount invocation: 


  mount -v --bind /dev $LFS/dev


And from section 6.2.3 the remaining mount invocations: 


  mount -vt devpts devpts $LFS/dev/pts -o gid=5,mode=620
  mount -vt proc proc $LFS/proc
  mount -vt sysfs sysfs $LFS/sys
  mount -vt tmpfs tmpfs $LFS/run



Ted's test of cut-and-paste text to permit running all five mount invocations with one text copy action . . . Ted noting the backslashes for line continuation don't work, and thinking on this syntax it makes sense that we need separate each mount invocation, as these are complete commands. Otherwise the second `mount` is parsed by the shell as an rgument to the first appearance of `mount` . . . 


mount -v --bind /dev $LFS/dev ;\
mount -vt devpts devpts $LFS/dev/pts -o gid=5,mode=620 ;\
mount -vt proc proc $LFS/proc ;\
mount -vt sysfs sysfs $LFS/sys ;\
mount -vt tmpfs tmpfs $LFS/run


^ chapter 6.4 - entering the chroot environment


Taken directly from the chapter: 


chroot "$LFS" /tools/bin/env -i \
    HOME=/root                  \
    TERM="$TERM"                \
    PS1='\u:\w\$ '              \
    PATH=/bin:/usr/bin:/sbin:/usr/sbin:/tools/bin \
    /tools/bin/bash --login +h



^ chapter 5.5 - gcc first pass

Chapter 5.5, building gcc first pass, took about sixty three (63) minutes:

user    32m31.794s
sys     5m49.582s

lfs@localhost:/mnt/lfs/sources/glibc-2.26/build$


Linux From Scratch chapter 5 has thirty seven sections. There was not a pressing need or a lot of details Ted found worth noting in most of these sections, the majority of which are dedicated to packages built in the first package building phase of LFS target system creation. These packages are all built as the user 'lfs', and with the environment variable $LFS set, in our case Ted's case, to /mnt/lfs.

An important instruction to follow from the last section of chapter 5, section 5.37: 


  " Note
 
   The commands in the remainder of this book must be performed while logged in as user root and no longer as user lfs. Also, double check that $LFS is set in root's environment."



^ LFS 8.1 chapter 6.5 - create new system directories

Some captured terminal work, following steps in LFS 8.1 book, chapter 6.5:

^ Uses of patch during LFS 8.1 chapter 5


Ted noting that as of 2017 later summer, among the Linux From Scratch 8.1 packages there are six which download with associated patch files. These patches are important to apply after un-archiving given package, and before preparing to compile given package:

^     Aside:  LFS 8.1 chapter 6.9 - glibc-2.26 programs and libraries

Really interesting section of the LFS 8.1 book here, chapter 6.9, which describes some of the utilities which come with GNU C library project. Quoting this book these utilities include "catchsegv, gencat, getconf, getent, iconv, iconvconfig, ldconfig, ldd, lddlibc4, locale, localedef, makedb, mtrace, nscd, pldd, sln, sotruss, sprof, tzselect, xtrace, zdump, and zic".

^ LFS 8.1 chapter 6.16 - binutils-2.29 requires 4.2 GB disk space!


Ok we've run into a too small partition for our root LFS file system. 7.6GB was not sufficient, though in an early chapter (chapter 2 or 3 of the LFS 8.1 book) Ted recalls there being word that a partition between five (5) and ten (10) GB would typically be sufficient to compile and install all Linux From Scratch programs. Ted now looking to re-partitioning software options under Linux . . .

Ok, got the partition resized, and then the file system on the root LFS partition resized too. Took a few notes and command line captures, which are in the wiki page titled Resize partition and file system.

Moving on and building binutils-2.29, found two tests to fail during the mandatory `make -k check` step. Failures noted here in case there are problems in later steps of the LFS 8.1 system build process:

Ted noting that the second failure is noted in LFS 8.1 as a known failure, and doesn't break the overall process or target system building.



^ LFS 8.1 chapter 6.20, gcc-7-2-.0

Ted noting that after compiling gcc using the new LFS tools from chapter 5, a check that the new gcc of chapter 6 sees correct header files gives slightly lesser results than what's in chapter 6.20. The book and chapter say to expect, 


#include <...> search starts here:
 /usr/lib/gcc/x86_64-pc-linux-gnu/7.2.0/include
 /usr/local/include
 /usr/lib/gcc/x86_64-pc-linux-gnu/7.2.0/include-fixed
 /usr/include


But on our i686 host Ted obtains from the same post-gcc-build test: 


root:/sources/gcc-7.2.0/build# grep -B4 '^ /usr/include' dummy.log
#include "..." search starts here:
#include <...> search starts here:
 /usr/lib/gcc/i686-pc-linux-gnu/7.2.0/include
 /usr/lib/gcc/i686-pc-linux-gnu/7.2.0/include-fixed
 /usr/include
root:/sources/gcc-7.2.0/build#


We're missing /usr/local/include among gcc's search paths. Not sure why, nor whether this is a deal breaker going forward with the LFS 8.1 build - TMH

To better understand Posix regular expressions, Ted to return and look at differences between old and amended versions of bzip2 makefile here in LFS 8.1 chapter 6.21 . . .

Was simply looking for latest package compiled and installed, following LFS book 8.1. But instead found permissions to differ. Perhaps some of the installed packages reflect those originally downloaded by the 'lfs' user. For some reason it was necessary to download some packages again after remounting the LFS partition and resuming work following a power-down event over two days' time . . .
