The build was failing with duplicate symbol errors with -fno-common. This is the default in GCC 10 and later, and explicitly enabled in some distributions to catch problems like this. There were two causes: - Prog and shadow_logfd were defined in a header file that was included in multiple other files. Fix this by defining them once in shadowlog.c, and having extern declarations in the header. - Most of the tools (except id/nologin) also define a Prog variable, which is not intended to alias the one in the library. Fix this by renaming Prog in the library to shadow_progname, which also matches the new accessor functions for it.
shadow-utils
Introduction
The shadow-utils package includes the necessary programs for converting UNIX password files to the shadow password format, plus programs for managing user and group accounts. The pwconv command converts passwords to the shadow password format. The pwunconv command unconverts shadow passwords and generates a passwd file (a standard UNIX password file). The pwck command checks the integrity of password and shadow files. The lastlog command prints out the last login times for all users. The useradd, userdel, and usermod commands are used for managing user accounts. The groupadd, groupdel, and groupmod commands are used for managing group accounts.
