Re: [libvirt] [PATCH] util: fix build on non-Linux

Build fails on non-Linux systems with this error: CC util/libvirt_util_la-virnetdev.lo util/virnetdev.c:364:1: error: unused function 'virNetDevReplaceMacAddress' [-Werror,-Wunused-function] virNetDevReplaceMacAddress(const char *linkdev, ^ util/virnetdev.c:406:1: error: unused function 'virNetDevRestoreMacAddress' [-Werror,-Wunused-function] virNetDevRestoreMacAddress(const char *linkdev, ^ 2 errors generated. The virNetDev{Restore,Replace}MacAddress() functions are only used by VF-related routines that are available on Linux only. So move these functions under the same #ifdef. --- src/util/virnetdev.c | 176 ++++++++++++++++++++++++++------------------------- 1 file changed, 89 insertions(+), 87 deletions(-) diff --git a/src/util/virnetdev.c b/src/util/virnetdev.c index b7ea524..5069064 100644 --- a/src/util/virnetdev.c +++ b/src/util/virnetdev.c @@ -351,93 +351,6 @@ int virNetDevGetMAC(const char *ifname,
