I see the same problem when trying to build current to of tree
(mdadm-4.1-74-g5cfb79d):
-> make raid6check
...
gcc -Wall -Werror -Wstrict-prototypes -Wextra -Wno-unused-parameter -Wimplicit-fallthrough=0 -O2 -DSendmail=\""/usr/sbin/sendmail -t"\" -DCONFFILE=\"/etc/mdadm.conf\" -DCONFFILE2=\"/etc/mdadm/mdadm.conf\" -DMAP_DIR=\"/run/mdadm\" -DMAP_FILE=\"map\" -DMDMON_DIR=\"/run/mdadm\" -DFAILED_SLOTS_DIR=\"/run/mdadm/failed-slots\" -DNO_COROSYNC -DNO_DLM -DVERSION=\"4.1-74-g5cfb79d\" -DVERS_DATE="\"2020-04-27\"" -DUSE_PTHREADS -DBINDIR=\"/sbin\" -o dlink.o -c dlink.c
In function "dl_strndup",
inlined from "dl_strdup" at dlink.c:73:12:
dlink.c:66:5: error: "strncpy" output truncated before terminating nul copying as many bytes from a string as its length [-Werror=stringop-truncation]
66 | strncpy(n, s, l);
| ^~~~~~~~~~~~~~~~
dlink.c: In function "dl_strdup":
dlink.c:73:31: note: length computed here
73 | return dl_strndup(s, (int)strlen(s));
| ^~~~~~~~~
cc1: all warnings being treated as errors
removing the "-Werror" from the CWFLAGS setting in the Makefile then
leads to:
...
gcc -O2 -o raid6check raid6check.o restripe.o sysfs.o maps.o lib.o xmalloc.o dlink.o
/usr/bin/ld: sysfs.o: in function `sysfsline':
sysfs.c:(.text+0x2707): undefined reference to `parse_uuid'
/usr/bin/ld: sysfs.c:(.text+0x271a): undefined reference to `uuid_zero'
/usr/bin/ld: sysfs.c:(.text+0x2721): undefined reference to `uuid_zero'
This might come from commit b06815989 "mdadm: load default
sysfs attributes after assemblation"; mdadm-4.1 builds ok.
Build tests were run on Fedora 32.
Best regards,
Wolfgang Denk

Calm down, it's *__only* ones and zeroes.
