7.6. Shadow-4.5

The Shadow package contains programs for handling passwords in a secure way.

7.6.1. Installation of Shadow

Disable the installation of the groups program and man pages, as better versions of these programs are provided by Coreutils, Util-linux and Man-pages. Also, prevent Shadow from setting the suid bit on its installed programs: 

cp -v src/Makefile.in{,.orig}
sed -e 's/groups$(EXEEXT) //' \
    -e 's/\(^suidu*bins = \).*/\1\\/' \
    src/Makefile.in.orig > src/Makefile.in

Tell Shadow to use passwd in /tools/bin: 

cat > config.cache << "EOF"
shadow_cv_passwd_dir=/tools/bin
EOF

Prepare Shadow for compilation: 

./configure \
    --prefix=/tools \
    --build=${CLFS_HOST} \
    --host=${CLFS_TARGET} \
    --cache-file=config.cache

Compile the package: 

make

Install the package: 

make install
