5.12. Shadow- - Native

5.12.1. Installation of Shadow

The following patch fixes an issue in useradd, where it only accepts group names, not group id numbers:

patch -Np1 -i ../shadow-

The following patch changes the hard-coded /etc in the sources to whatever was passed to configure. It also allows the utilities to run as a user other then root:

patch -Np1 -i ../shadow-

The following value is added to config.cache to make sure that the passwd program is found:

echo "shadow_cv_passwd_dir=${CLFS}/bin" > config.cache

The following value causes Shadow to use its internal lckpwdf instead of the one provided by Glibc. The one provided by Glibc will attempt to modify the host system:

echo "ac_cv_func_lckpwdf=no" >> config.cache

Prepare Shadow for compilation:

./configure --prefix=${CLFS}/cross-tools --sbindir=${CLFS}/cross-tools/bin \
    --sysconfdir=$CLFS/etc --disable-shared --without-libpam --without-audit \
    --without-selinux --program-prefix=${CLFS_TARGET}- --cache-file=config.cache

Add the proper prefix to the passwd program:

cp config.h{,.orig}
sed "/PASSWD_PROGRAM/s/passwd/${CLFS_TARGET}-&/" config.h.orig > config.h

Compile the package:


Install the package:

make install


The tools built on this page will be used later in this book.
