The NPth package contains a very
portable POSIX/ANSI-C based library for Unix platforms which
provides non-preemptive priority-based scheduling for multiple
threads of execution (multithreading) inside event-driven
applications. All threads run in the same address space of the
server application, but each thread has its own individual
program-counter, run-time stack, signal mask and errno variable.

Create the PKGBUILD for the NPth package with the following
commands:
mkdir /sources/npth
cd /sources/npth
cat > PKGBUILD << "REALEOF"
# Maintainer: Linux From Scratch <lfs-dev@lists.linuxfromscratch.org>
pkgname="npth"

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 npth-1.8-1-$(uname -m).pkg.tar.xz \
/srv/pacman/repos/LFS/
repo-add /srv/pacman/repos/LFS/LFS.db.tar.xz \
/srv/pacman/repos/LFS/npth-1.8-1-$(uname -m).pkg.tar.xz
Update the local cache and install the NPth package:
pacman -Syu
pacman -S npth --overwrite \* -dd --noconfirm
Finally, copy the source files into the source repository and clean
up the build directory:
mkdir /srv/pacman/source/LFS/npth
cp PKGBUILD /srv/pacman/source/LFS/npth
cd /sources
rm -rf npth
