names of packages. Clarified verbiage in re PIE & ASLR. Improved the
description of SSP, and tightened it up. Clarified the instructions
for running tests concurrently. Modified descriptions of tests that
fail. Patched up punctuation. Spelled "set up" correctly: "setup" is
a noun. The phrasal verb used here is spelled as two words. Use the
word "directives" to describe "#include" and similar preprocessor
instructions. Add periods to some otherwise complete sentences.
I was using the transitive verb "process" here, not the noun. Use
another word to avoid the ambiguity. Also add "and groups" because
there is also subgid alongside subuid.
sort-NaN-infloop no longer fails now, it seems covered up by PIE or SSP.
test-getlogin keeps failing in Bruce's build. Not sure how to reproduce
the failure deterministically.
We need to enable decimal float here or MPFR will be built w/o decimal
float support. Then 2 of 183 tests will be skipped, and this will also
cause an ICA issue.
Q: Why we need decimal float in pass 1?
A: We need pass-1 GCC with decimal float support to build decimal float
routines in pass-2 libgcc.
verbiage. Used the subjunctive mood once. "Test suite" is two words, not
one. Patched some unidiomatic English. Used the plural "headers" when
discussing ELF objects. Used singular verbs to describe "gprofng", for
consistency with other items.
modifies the plural noun "libraries"; it must use a plural verb.
Clarified how many "configure" options Readline uses. Tightened the
prose, and used the definite article in lieu of the indefinite article,
because only one readline.pc file can possibly be the "correct" one.
We don't recommend customizing optimizations, but we use optimizations
provided by package default or release build mode.
Reword the paragraph so the people won't be puzzled once they see
"--enable-optimizations" in Python, or "--buildtype=release" (to prevent
unoptimized build) in BLFS meson commands.
"Duplicated copy" is wrong IMO. If you copy A to B, B won't be changed
when you modify A. But if you bind mount A to B, B will reflect any
change made to A.
Again copy something from mount(2):
A bind mount makes a file or a directory subtree visible at another
point within the single directory hierarchy.
Things are a little tricky:
1. If the host is "modern" (any desktop distro after 2013), the kernel
supports devtmpfs and the host udev will do adjustments to the
devtmpfs. All instances of devtmpfs shares the same content so we'll
see the work of both the kernel and the host udev in chroot.
2. If the host is old but the kernel supports devtmpfs (i. e. the host
is not using devtmpfs for its /dev), when we mount devtmpfs on
$LFS/dev we'll see the work of the kernel in chroot, but not the work
of udev. **Building LFS does not need any work of udev.**
3. If the host is very old and the kernel does not support devtmpfs at
all, we can't mount devtmpfs.
Mounting a devtmpfs will work for 1 and 2, while bind mounting will work
for 1, 2, and 3. So we use bind mounting here.
I don't want to squash all these details into the book, so just remove
the false statement here.
Technically chroot command "tells" bash nothing. It basically calls
chroot("$LFS"), then chdir("/"), then
execve(["/usr/bin/env", "-i", ...]). The kernel also does not tell bash
something like "hey, the root is now $LFS" but just executes (almost) all
system calls from bash as-if $LFS is /.
The man page of chroot says:
DESCRIPTION
Run COMMAND with root directory set to NEWROOT.
Just use the same grammar construction here.
Please try not to use the "replace" feature of the text editor blindly.
Appendix C of the GNU C Library Reference Manual clearly says:
'--disable-werror'
By default, the GNU C Library is built with '-Werror'. If you wish
to build without this option (for example, if building with a newer
version of GCC than this version of the GNU C Library was tested
with, so new warnings cause the build with '-Werror' to fail), you
can configure with '--disable-werror'.
