LZO is a data compression library which is suitable for data decompression and compression in real-time. This means it favors speed over compression ratio.
Create the PKGBUILD for the LZO package with the following commands:
mkdir /sources/lzo
cd /sources/lzo
cat > PKGBUILD << "REALEOF"
# Maintainer: Linux From Scratch <lfs-dev@lists.linuxfromscratch.org>
pkgname="lzo"
pkgver="2.10"
pkgrel="1"
pkgdesc="A data compression library which is suitable for data decompression and compression in real-time."

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 lzo-2.10-1-$(uname -m).pkg.tar.xz \
/srv/pacman/repos/LFS/
repo-add /srv/pacman/repos/LFS/LFS.db.tar.xz \
/srv/pacman/repos/LFS/lzo-2.10-1-$(uname -m).pkg.tar.xz
Update the local cache and install the LZO package:
pacman -Syu pacman -S lzo --overwrite \* -dd --noconfirm
Finally, copy the source files into the source repository and clean up the build directory:
mkdir /srv/pacman/source/LFS/lzo cp PKGBUILD /srv/pacman/source/LFS/lzo cd /sources rm -rf lzo
