The linker seems to be indicating that it's not present in the standard library.According to the man page, it's part of the standard libc:And the answer is B) it's a macro that calls a function with a different name; from <sys/capsicum.h> in FreeBSD SVN: #define cap_rights_init(...) \ __cap_rights_init(CAP_RIGHTS_VERSION, __VA_ARGS__, 0ULL) cap_rights_t *__cap_rights_init(int version, cap_rights_t *rights, ...); The same is true of cap_rights_set, cap_rights_clear, and cap_rights_is_set, so we can't check *any* of them with AC_CHECK_FUNCS. The only one we're checking for is cap_rights_init, though, so removing that from the list (with a comment explaining why we can't check for it) would suffice.
