Dependencies

• Cracklib
• PAM Library

Non-Multilib

Configure and compile the package:

./configure --libdir=/lib -sysconfdir=/etc --enable-shared \
  --without-audit --without-selinux --with-libcrack --with-libpam &&
sed -i 's/groups$(EXEEXT) //' src/Makefile && 
sed -i '/groups/d' man/Makefile &&
make

Install the package:

make install &&
mv /usr/bin/passwd /bin &&
mv /lib/libshadow.{a,la} /usr/lib &&
rm /lib/libshadow.so &&
LIBNAME=`cat lib/libshadow.la | grep library_names | cut -f2 -d"'" | cut -f2 -d" "` &&
ln -sf ../../lib/$LIBNAME /usr/lib/libshadow.so &&
install -d /etc/default 

Setup Configuration files:

This section makes sure login.defs is compatible with PAM

cp etc/login.defs /etc/login.defs 
sed -i -e 's@#MD5_CRYPT_ENAB.no@MD5_CRYPT_ENAB yes@' \
       -e 's@/var/spool/mail@/var/mail@' \

for function in $FUNCTIONS; do
     sed -i "s/^$function/# &/" /etc/login.defs
done

/etc/default/useradd

With the PAM configuration that is in CBLFS, this is the only information needed in /etc/default/useradd.

cat > /etc/default/useradd << "EOF"
HOME=/home
INACTIVE=-1
SHELL=/bin/bash
CREATE_MAIL_SPOOL=no
EOF

Multilib

32Bit

Configure and compile the package:

CC="gcc ${BUILD32}" ./configure --libdir=/lib -sysconfdir=/etc --enable-shared \
  --without-audit --without-selinux --with-libcrack --with-libpam &&
sed -i 's/groups$(EXEEXT) //' src/Makefile && 
sed -i '/groups/d' man/Makefile &&
make

Install the package:

make install &&
mv /usr/bin/passwd /bin &&
mv /lib/libshadow.{a,la} /usr/lib &&
rm /lib/libshadow.so &&
LIBNAME=`cat lib/libshadow.la | grep library_names | cut -f2 -d"'" | cut -f2 -d" "` &&
ln -sf ../../lib/$LIBNAME /usr/lib/libshadow.so

N32

Configure and compile the package:

The sed at the beginning modifies the libtool that comes with shadow to look in the /lib32, by default this libtool only searchs /lib, /usr/lib, or /usr/local/lib32.

sed -i libtool \
     -e 's@\(^sys_lib_search_path_spec=\).*@\1"/lib32 /usr/lib32 /usr/local/lib32"@g' \
     -e 's@\(^sys_lib_dlsearch_path_spec=\).*@\1"/lib32 /usr/lib32 /usr/local/lib32"@g' &&
CC="gcc ${BUILDN32}" ./configure --libdir=/lib32 -sysconfdir=/etc --enable-shared \
  --without-audit --without-selinux --with-libcrack --with-libpam &&
sed -i 's/groups$(EXEEXT) //' src/Makefile && 
sed -i '/groups/d' man/Makefile &&
make

Install the package:

make install &&
mv /usr/bin/passwd /bin &&
mv /lib32/libshadow.{a,la} /usr/lib32 &&
rm /lib32/libshadow.so &&
LIBNAME=`cat lib/libshadow.la | grep library_names | cut -f2 -d"'" | cut -f2 -d" "` &&
ln -sf ../../lib32/$LIBNAME /usr/lib32/libshadow.so

64Bit

The sed at the beginning modifies the libtool that comes with shadow to look in the /lib64, by default this libtool only searchs /lib, /usr/lib, or /usr/local/lib.

sed -i libtool \
     -e 's@\(^sys_lib_search_path_spec=\).*@\1"/lib64 /usr/lib64 /usr/local/lib64"@g' \
     -e 's@\(^sys_lib_dlsearch_path_spec=\).*@\1"/lib64 /usr/lib64 /usr/local/lib64"@g' &&
CC="gcc ${BUILD64}" ./configure --libdir=/lib64 -sysconfdir=/etc --enable-shared \
  --without-audit --without-selinux --with-libcrack --with-libpam &&
sed -i 's/groups$(EXEEXT) //' src/Makefile && 
sed -i '/groups/d' man/Makefile &&
make

Install the package:

make install &&
mv /usr/bin/passwd /bin &&
mv /lib64/libshadow.{a,la} /usr/lib64 &&
rm /lib64/libshadow.so &&
LIBNAME=`cat lib/libshadow.la | grep library_names | cut -f2 -d"'" | cut -f2 -d" "` &&
ln -sf ../../lib64/$LIBNAME /usr/lib64/libshadow.so
