This commit renames extract-build-times.py to dump-build-times and
makes use of it after every pass in baserock-bootstrap. This will
add the build times of all chunks to the bootstrap log.

At some point we will want to have a concept of a target architecture
that includes default compiler flags etc. but for now, --target-cflags
will do.

The combination -mfpu=vfpv3-d16 =mfloat-abi=hard is only supported from
GCC > 4.5, according to
http://wiki.debian.org/ArmHardFloatPort/VfpComparison
If we want hard float we'll have to switch to a more recent version of
GCC installed in the squeeze chroot we run baserock-bootstrap in.
Upstream GCC 4.5 supports it, as does the CodeSourcery 2009q1 compiler.

The --target-cflags option is really just a temporary solution. At some
point we will want to have a proper target architecture/device
description that morph uses to define compiler flags etc.
For now, I hope this will do.

It might be the cause of weird internal binutils and gcc errors.

bash variable expansion behaves a little differently to sed
the final section's / are not treated specially

pwd may be just /, at which point LFS begins with //
Python's distutils fails to compile when --prefix is //tree/tools
and --root is given as it installs to //tree/tools but tries to
compile files in --root.
This works without the double slash, so fix it

This reverts commit e522e8d4798dec4092fabaeb89b532e970c3296f.
pwd does not always end with /

This strangely breaks python's distutils so setup.py fails.
if --prefix is //tree/tools then it ignores --root when it copies
the files, however when it later goes to compile the scripts
it does use --root so it fails to find the files.

Pass 1 should have $tools first in the path, otherwise the wrong
compiler will be used

This should stop tar from replacing symbolic links with directories
and instead follow the symbolic links, extracting the files into
the linked directories

This fixes a strange issue where the file binary will segfault in
__libc_start_main() because it uses the host runtime dynamic linker
and not the on in /tree/tools. The host's ld-linux comes from eglibc
2.12 and the rtld_global_ro struct in 2.12 has a different size than the
one in eglibc 2.15. This, the _rtld_global_ro.dl_audit pointer gets
corrupted and __libc_start_main() segfaults.
This is miraculously fixed by building file immediately after zlib.

This was mentioned on
http://www.linuxfromscratch.org/hints/downloads/files/lfs70armhint.txt
as one of the things that need to be changed to build LFS 7.0 on ARM.

flex is needed in binutils
tempdir needs to be set as binutils' install script expects the
files to be in an absolute path
also use $LFS in paths
|
| | |
| |
| |
| |
| |
| | |
binutils ./configure fails because distcc is not found in the
debian squeeze chroot. I am not sure how it is trying to invoke
distcc, but we probably don't want it in pass1 anyway

baserock-bootstrap: set cachedir so that the git cache
can be reused in pass 2 onwards
run-bootstrap-in-chroot: add more passes

run-bootstrap-in-chroot: add cliapp to squeeze-chroot
baserock-bootstrap:
* remove use of sudo, the script expects to be run with
sufficient privilidges
* remove multiple unused variables and functions
* replace the build instructions with a call to morph with a
stratum that should have all the required programs
with --prefix and --toolchain-target set

This variable can optionally be set outside the squeeze chroot (that is,
outside the run-bootstrap-in-chroot script. The directory is then bind
mounted into the chroot and baserock-bootstrap will set its CCACHE_DIR
to the location inside the chroot.

This makes it easier to re-run the bootstrap script to
resume building.

The git-base-urls specified are now the defaults, so specifying
them should be redundant.
Also quoted the output for staging-filler

if it doesn't get replaced then a command may
try to use /tools/bin/env

this is pretty much just a copy of the pass 2 thing
this needs a cleanup, as there is duplicated functionality and
clashing names
|
| |
|
|
|

This is to make snapshots of them be small. pass2a and 2b pretty
much halved in size.

The git cache is currently under the chunk cache, so
moving the chunk cache moves the gits.
We don't want to have to do that all again.
Also added quotes in case $LFS ever has spaces in it
