Turns out that building Busybox 1.36.1 with this new musl version, on 32-bit RISC-V, fails with: util-linux/hwclock.c: In function 'set_kernel_tz': util-linux/hwclock.c:142:27: error: 'SYS_settimeofday' undeclared (first use in this function); did you mean 'xsettimeofday'? 142 | int ret = syscall(SYS_settimeofday, NULL, tz); | ^~~~~~~~~~~~~~~~ | xsettimeofday util-linux/hwclock.c:142:27: note: each undeclared identifier is reported only once for each function it appears in Busybox already includes some slightly convoluted sorcery to deal with musl: static void set_kernel_tz(const struct timezone *tz) { #if LIBC_IS_MUSL /* musl libc does not pass tz argument to syscall * because "it's deprecated by POSIX, therefore it's fine * if we gratuitously break stuff" :( */ #if !defined(SYS_settimeofday) && defined(SYS_settimeofday_time32) # define SYS_settimeofday SYS_settimeofday_time32 #endif int ret = syscall(SYS_settimeofday, NULL, tz); #else int ret = settimeofday(NULL, tz); #endif if (ret) bb_simple_perror_msg_and_die("settimeofday"); } I am not sure whether this is a Busybox problem or a musl problem, which is why I'm cross-posting on both mailing lists.
