The libarchive library provides a single interface for reading/writing various compression formats.
Create the PKGBUILD for the libarchive package with the following commands:
mkdir /sources/libarchive
cd /sources/libarchive
cat > PKGBUILD << "REALEOF"

Prepare the build directory for the pacman user and build the package:
chown -R root:pacman . chmod 2775 . chmod 664 PKGBUILD su pacman -c 'makepkg -L --nodeps'
Add the newly created package to the central package repository:
cp libarchive-3.7.8-1-$(uname -m).pkg.tar.xz \
/srv/pacman/repos/LFS/
repo-add /srv/pacman/repos/LFS/LFS.db.tar.xz \
/srv/pacman/repos/LFS/libarchive-3.7.8-1-$(uname -m).pkg.tar.xz
Update the local cache and install the libarchive package:
pacman -Syu pacman -S libarchive --overwrite \* -dd --noconfirm
Finally, copy the source files into the source repository and clean up the build directory:
mkdir /srv/pacman/source/LFS/libarchive cp PKGBUILD /srv/pacman/source/LFS/libarchive cd /sources rm -rf libarchive
