hmm, this is related to replacing "memcmp" by dedicated structure entry compare.

    ...
     (&cache_lu_ipv6addr.in6_addr.s6_addr32[0] == &ipv6addrp->in6_addr.s6_addr32[0])
    ...

Looks like in "homebrew" something is missing in the header definition.

At least Enterprise Linux >= 7 has defined in /usr/include/netinet/in.h:

#define s6_addr                 __in6_u.__u6_addr8
#ifdef __USE_MISC
# define s6_addr16              __in6_u.__u6_addr16
# define s6_addr32              __in6_u.__u6_addr32
#endif

Can you check content of your "in.h"

[pbiering]

fixed by 6c89a41 (run some FreeBSD regression tests)
3.0.2 will be released next days, "gmake test" should then work also proper on *BSD

[pbiering]

fixed a lot of FreeBSD issues, should also fix build on osx: https://github.com/pbiering/ipv6calc/releases/tag/3.0.2

[chenrui333]

let me give a shot.

[chenrui333]

ipv6calc 3.0.2 works for me, see details in Homebrew/homebrew-core#68962

Thanks @pbiering! Closing the issue now.
