Hi; thanks for this report. (This kind of bug report is better sent to qemu-devel or to the launchpad bug tracker -- qemu-discuss is mostly user-to-user conversations, and developers tend to be on -devel; I've cc'd -devel on this.) Our official support policy is that we support building with the two most recent versions of macOS; in practice we might support building with some earlier versions; as of commit 5588840ff77800e839 we definitely dropped support for anything earlier than 10.10. So in theory we don't strongly care about anything before 10.13 at the moment; but if it's easy to avoid the problem it might be worth doing that. Alex, it looks like the relevant commit was one of yours. Could you have a look at how easy it would be to support systems without clock_gettime/CLOCK_MONOTONIC ? I notice that other places in QEMU have #ifdeffery for a lack of CLOCK_MONOTONIC, so we should ideally be consistent, and either support systems without it, or else say we require it and remove the remaining legacy ifdefs... thanks -- PMM
