Hi All,
As promised in an email earlier on this list, below I have provided a
description of the deviations required for me to successfully build the
initial tools in chapter 5 which are separated by section number.
Attached are a copy of all patches which have been added or changed to
get to this stage. Once blended with the HLFS book, you should be able
to successfully build a functional set of initial tools.
Currently I am working through chapter 6 and will provide a similar
report once I have completed, although it would appear at first glance
that I have a lot of work ahead of me as I already have half a page of
notes and I have just started the butterfly toolchain.
I am more than happy to answer any questions about my work and this
document which you might have.
Finally, I would also like to thank Rob van Dam for his assistance in
working through and solving these issues.
Kind Regards,
Brian.
Chapter 5 Build Issues
======================
5.4 uClibc-0.9.29uClibc-0.9.29
------------------------------
- Applied a patch located by Rob van Dam called
uClibc-0.9.29-fix-internal_function-definition.patch which allows
gettext to compile correctly.
- Applied a patch I created called
uClibc-0.9.29-fix-error_print_progname.patch which also allows gettext
to compile which enables access to the error_print_progname variable.
5.9 Cocoon Toolchain
--------------------
- We need to execute the cleanup for fixincludes after installation as
we did in the Embryo Toolchain. This will enable the Bash build to
complete correctly.
Command:
GCC_INCLUDEDIR=`dirname $(gcc -print-libgcc-file-name)`/include &&
find ${GCC_INCLUDEDIR}/* -maxdepth 0 -xtype d -exec rm -rvf '{}' \; &&
rm -vf `grep -l "DO NOT EDIT THIS FILE" ${GCC_INCLUDEDIR}/*` &&
unset GCC_INCLUDEDIR
5.25 Perl-5.8.8
---------------
- Corrected the content of the patch being applied to perl as the one
specified was for the build using glibc not uClibc. The difference is
the name of the libc.so file. glibc = libc.so.6, uClibc = libc.so.0. The
name of the new patch file is perl-5.8.8-uClibc-2.patch.
5.26 Sed-4.1.5
--------------
- Applied a patch located by Rob van Dam called sed-4.1.4-uClibc-1.patch
which corrects the build proceedure for sed when linked against uClibc.
This patch fixes the "Memory Exhausted" error.
5.32 Stripping
--------------
- It should be documented that the stripping must be run as root. I
noticed that there were some permission errors when stripping as the
hlfs user.

Initial Package Version: 5.8.8
Origin: based on current LFS-BOOK patch (perl-5.8.0-libc-2.patch)
Description: this patch adapts some hard-wired paths to the C library.
It uses the $prefix variable to locate the correct libc.
