8.44. Grep-3.11

8.44.1. Installation of Grep

First, remove a warning about using egrep and fgrep that makes tests on some packages fail:

Create the PKGBUILD for the Grep package with the following commands:

mkdir /sources/grep
cd /sources/grep
cat > PKGBUILD << "REALEOF"
# Maintainer: Linux From Scratch <lfs-dev@lists.linuxfromscratch.org>

pkgname="grep"
pkgver="3.11"
pkgrel="1"
pkgdesc="The Grep package contains programs for searching through the contents of files."
arch=('x86'
      'x86_64')

license=('GPLv3')
groups=('core')
depends=('glibc'
         'rootfs')
makedepends=('bash'
             'binutils'

prepare(){
  cd ${pkgname}-${pkgver}
  # First, remove a warning about using egrep and fgrep that makes tests on some packages fail
  sed -i "s/echo/#echo/" src/egrep.sh
}

build(){
  cd ${pkgname}-${pkgver}
  ./configure --prefix=/usr
  make
}

check(){
  cd ${pkgname}-${pkgver}
  make check
}

package(){
  cd ${pkgname}-${pkgver}
  make DESTDIR=${pkgdir} install
}
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 grep-3.11-1-$(uname -m).pkg.tar.xz \
   /srv/pacman/repos/LFS/
repo-add /srv/pacman/repos/LFS/LFS.db.tar.xz \
         /srv/pacman/repos/LFS/grep-3.11-1-$(uname -m).pkg.tar.xz

Update the local cache and install the Grep package:

pacman -Syu
pacman -S grep --overwrite \* -dd --noconfirm

Finally, copy the source files into the source repository and clean up the build directory:

mkdir /srv/pacman/source/LFS/grep
cp PKGBUILD /srv/pacman/source/LFS/grep
cd /sources
rm -rf grep
