7.7. Shadow-4.1.5.1

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

7.7.1. Installation of Shadow

Run the following sed command to disable the installation of the groups and nologin programs, as better versions of these programs are provided by other packages, and prevent Shadow from setting the suid bit on its installed programs: 

cp -v src/Makefile.in{,.orig}
sed -e 's/groups$(EXEEXT) //' \
    -e 's/= nologin$(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
