[Xen-devel] building error

[Wen Congyang <wency@xxxxxxxxxxxxxx>]

When I try to build xen on fc21, I meet the following errors:
drivers/net/ath/ath9k/ath9k_ar9003_phy.c: In function âar9003_hw_ani_controlâ:

I know my gcc has some problems, and will generate wrong bin file(We have 
discussed
it earlier).
But this building error is new problem. Do we have any plan to use newer ipxe?

I update ipxe to avoid the building error, and I meet the following error:
hw/virtio/virtio-rng.c: In function âvirtio_rng_device_realizeâ:
hw/virtio/virtio-rng.c:152:31: error: logical not is only applied to the left 
hand side of comparison [-Werror=logical-not-parentheses]
     if (!vrng->conf.period_ms > 0) {
                               ^

It seems that qemu have some problems.

Thanks
