Re:Re: LFS6.4 step 5.17 compiling coreutils-6.12 error
Thank everyone!!!
I have fixed it.
Coreutils whose version is greater than 6.0 needs selinux, which can be see
from source file:
#include selinux/selinux.h or / and
#include selinux/context.h
These are host system's header files,so we must replace these file with
se-selinux.in.h
se-context.in.h
They are coreutils's built-in header file for host in which no selinux is not
supported.
My scripts:
for file in $(find ./ -name *.c -o -name *.h)
do
cp -uv $file{,.orig} \
sed -e 's...@#include selinux/selinux.h@#include
se-selinux.in.h@g' \
-e 's...@#include selinux/context.h@#include
se-context.in.h@g' $file.orig $file \
rm $file.orig \
touch $file
done
I have constructed the temporary system and entered the chroot environment
successfully!

Fair enough, I should have said fairly isolated at this point.
6.As you build Chapter 5, you get more of what you
previously build,
but there are libraries and headers from the host that are still
potentially available.The linker still uses the libraries in
/etc/ld.so.conf for your tools when building other programs.
Ah, I was thinking about that, too.There's probably some rpath

so if you built a system using a host cd
without(libselinux.so) -lselinux
you probably would of been fine. but if building
with ubuntu/fedora /lib/libselinux.so is there causing
coreutils to enable all support for SELinux
(but could be wrong);

You are talking to several hundred people. You are wrong. Coreutils does not need selinux. You should have in lib/config.h: /* Define to 1 if you have the selinux/context.h header file. */ /* #undef HAVE_SELINUX_CONTEXT_H */ /* Define to 1 if you have the selinux/flask.h header file. */ /* #undef HAVE_SELINUX_FLASK_H */ /* Define to 1 if you have the selinux/selinux.h header file. */ /* #undef HAVE_SELINUX_SELINUX_H */ If this is Chapter 5, then it might link selinux in, depending on the host. In chapter 6, it definitely will not find those headers and there will be no problem. If your host has the headers and not the libraries, then it is not set up properly. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

I'm not sure the configure file is the problem.
Can you try to issue:
echo 'main(){}' dummy.c
cc -v dummy.c 21 |grep include
rm dummy.c
and include the output here, I have a feeling there may be a problem with
gcc on your build.
Regards,

Just for kicks I just built up to gcc pass 2 in chapter 5 and issued the
commands above and this is my output:
snipped some junk
#include ... search starts here:

/mnt/data/data/build/lfs-main/lfs/lfs-testing/tools/bin/../lib/gcc/i686-pc-

/tools/include
If I'm reading the above correctly we're isolated from the host at this
point, with the exception of PATH. Binutils takes care of the library search
path and gcc takes care of the headers search path. Of course, there could be
some evil configure scripts that look in well known locations... I'm mostly
just thinking out loud here, but I'm hoping this can be confirmed so that I can
give advice and help troubleshoot in the future with a bit more certainty.

I haven't the source in front of me at the moment
for coreutils. but from looking at the errors
with chcon getfilecon etc.. those are all of the
tools to manage SELinux(i.g. ls -Z etc..)
your host system probably has libselinux installed
and my guess is coureutils has some mechanisms to check for
that, and if present enables SELinux support(without any switches in
configure).
my guess is either find a host system to build on
that has no libselinux so coreutils is built without SELinux support, or
with the host system your using now
My first build of LFS was on a system with SELinux support, and I
did not have this problem. This looks like a problem with gcc, or
some configuration error.
