Hi Michal, The IN6_IS_ADDR_UNSPECIFIED() function needs a struct in6_addr as argument. So changing the line in this way: - return IN6_IS_ADDR_UNSPECIFIED(&addr->data.inet6.sin6_addr.s6_addr); + return IN6_IS_ADDR_UNSPECIFIED(&addr->data.inet6.sin6_addr); it should work.

There's this macro IN6_IS_ADDR_UNSPECIFIED which seems to be portable, but it is not. On other architectures many errors are produced, e.g. on my ARM box I get:

CC libvirt_util_la-virsocketaddr.lo util/virsocketaddr.c: In function 'virSocketAddrIsWildcard': util/virsocketaddr.c:244:16: error: cast increases required alignment of target type [-Werror=cast-align] util/virsocketaddr.c: At top level: cc1: error: unrecognized command line option "-Wno-unused-command-line-argument" [-Werror] cc1: all warnings being treated as errors

Hence, we should drop its usage and move to memcmp instead. --- src/util/virsocketaddr.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
