I'm sorry...I don't speak english very well...
I have a problem in page 5.5 of Linux From Scratch 6.3...

In what directory I do this command?
Please!Help me!
Thanks a lot...

Unpack linux-2.6.23.12.tar.bz2, change into the top of the source tree (cd linux-2.6.23.12), and execute the commands from there.

Basically,

- Download the Linux kernel archive (in .tar.gz or .tar.bz2 format) into /usr/src.
- Unpack it (either by "tar -zxf linux*.tar.gz" or "tar -xjf linux*.tar.bz2").
- Symbolically link ("symlink") the directory to /usr/src/linux ("ln -s /usr/src/linux* /usr/src/linux").
- Go into the new directory ("cd /usr/src/linux").

Then, once your in this directory, you can run those commands: make mrproper, make headers_check, make INSTALL_HDR_PATH=dest headers_install, cp -rv dest/include/* /tools/include.

Code:

lfs@kubuntu:/mnt/lfs/sources$ sudo mv linux-2.6.22.5.tar.bz2 /usr/src/
[sudo] password for lfs:
lfs is not in the sudoers file.  This incident will be reported.
lfs@kubuntu:/mnt/lfs/sources$

Please, help me!

Do not, do not, do not put the Linux kernel source in your /usr/src. That is on your host system! If you execute the commands in the LFS book from /usr/src/linux, you will overwrite your host system's kernel headers.

Ensure that you are in $LFS/sources and then

Code:

tar xf linux-2.6.22.5.tar.bz2
cd linux-2.6.22.5
make mrproper
make headers_check
make INSTALL_HDR_PATH=dest headers_install
cp -rv dest/include/* /tools/include

Do not create the /usr/src/linux symlink ever on your LFS system. That hasn't been done for years, it is strongly discouraged by the kernel developers, and can cause system breakage.

I have a big problem:

Code:

lfs@kubuntu:/mnt/lfs/sources$ tar xf linux-2.6.22.5.tar.bz2
lfs@kubuntu:/mnt/lfs/sources$ cd linux-2.6.22.5
lfs@kubuntu:/mnt/lfs/sources/linux-2.6.22.5$ make mrproper
lfs@kubuntu:/mnt/lfs/sources/linux-2.6.22.5$ make headers_check
  CHK     include/linux/version.h
  UPD     include/linux/version.h
  HOSTCC  scripts/basic/fixdep

Help me please!What should I do?

This should give you some hints...

Code:

# Setup the package path and build directory.
CWD=`pwd`
TMP=/tmp
if [ ! -d $TMP ] ; then
   mkdir -pv $TMP    # Just in case /tmp doesn't exist for some reason. 
fi
PKG=$TMP/pkg-$PROG
rm -rf $PKG          # Make sure that this doesn't exist first.
mkdir -pv $PKG

# Extract and copy over the kernel headers. 
cd $TMP
rm -rf linux-2.6.23.12
tar -xvjf $CWD/linux-2.6.23.12.tar.bz2
