The recent deprecation in glibc (commit b76e065991ec) means the module will fail to build entirely: nss/libvirt_nss.c: In function '_nss_libvirt_gethostbyname_r': nss/libvirt_nss.c:363:13: error: RES_USE_INET6 is deprecated [-Werror] int af = ((_res.options & RES_USE_INET6) ? AF_INET6 : AF_INET); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This resolver option was removed shortly after being introduced, and application using it are already broken anyway. --- tools/nss/libvirt_nss.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/tools/nss/libvirt_nss.c b/tools/nss/libvirt_nss.c index b69e62c..9904026 100644 --- a/tools/nss/libvirt_nss.c +++ b/tools/nss/libvirt_nss.c @@ -360,9 +360,7 @@ NSS_NAME(gethostbyname)(const char *name, struct hostent *result, char *buffer, size_t buflen, int *errnop, int *herrnop) { - int af = ((_res.options & RES_USE_INET6) ?
