Same problem here on ~x86: fuzz.c:815:20: error: ‘sys_errlist’ undeclared (first use in this function) 815 | write(cpy_stderr,sys_errlist[errno],strlen(sys_errlist[errno])); | ^~~~~~~~~~~ sys_errlist is gone from glibc-2.32 and should be replaced (from glibc-2.32 changelog): * The functions strerrorname_np and strerrordesc_np have been added. The strerroname_np returns error number name (e.g. "EINVAL" for EINVAL) while strerrordesc_np returns string describing error number (e.g "Invalid argument" for EINVAL). Different than strerror, strerrordesc_np does not attempt to translate the return description, both functions return NULL for an invalid error number. They should be used instead of sys_errlist and sys_nerr, both are thread and async-signal safe. These functions are GNU extensions. * The deprecated symbols sys_errlist, _sys_errlist, sys_nerr, and _sys_nerr are no longer available to newly linked binaries, and their declarations have been removed from from <stdio.h>. They are exported solely as compatibility symbols to support old binaries. All programs should use strerror or strerror_r instead.
