6.5. Coreutils-8.32

The Coreutils package contains utilities for showing and setting the basic system characteristics.

Approximate build time: 0.6 SBU
Required disk space: 170 MB

6.5.1. Installation of Coreutils

Prepare Coreutils for compilation: 

./configure --prefix=/usr                     \
            --host=$LFS_TGT                   \
            --build=$(build-aux/config.guess) \
            --enable-install-program=hostname \
            --enable-no-install-program=kill,uptime

The meaning of the configure options:

--enable-install-program=hostname

This enables the hostname binary to be built and installed – it is disabled by default but is required by the Perl test suite.

Compile the package: 

make

Install the package: 

make DESTDIR=$LFS install

Move programs to their final expected locations. Although this is not necessary in this temporary environment, we must do so because some programs harcode executable locations: 

mv -v $LFS/usr/bin/{cat,chgrp,chmod,chown,cp,date,dd,df,echo} $LFS/bin
mv -v $LFS/usr/bin/{false,ln,ls,mkdir,mknod,mv,pwd,rm}        $LFS/bin
mv -v $LFS/usr/bin/{rmdir,stty,sync,true,uname}               $LFS/bin
mv -v $LFS/usr/bin/{head,nice,sleep,touch}                    $LFS/bin
mv -v $LFS/usr/bin/chroot                                     $LFS/usr/sbin
mkdir -pv $LFS/usr/share/man/man8
mv -v $LFS/usr/share/man/man1/chroot.1                        $LFS/usr/share/man/man8/chroot.8
sed -i 's/"1"/"8"/'                                           $LFS/usr/share/man/man8/chroot.8
