Re: [Xen-devel] Xen 4.4 - NetBSD libaio

[Miguel Clara <miguelmclara@xxxxxxxxx>]

Yes that it.

I don't know where its used, but that's what makes most sense.

I'm not much of a codder, but that part seems rather easy... I simply if checking if the OS is NETBSD.

Actually...

I guess that would do it?

Hrm, seem like this has come up before (I'd totally forgotten).

http://lists.xen.org/archives/html/xen-devel/2012-01/msg00499.html says
that "NetBSD provides the aio interface (IEEE Std 1003.1-2001
(``POSIX.1'')) via the POSIX real-time library (-lrt)." (which I suppose
is the same as what you were referring to)

On the other hand libaio is only used by blktap, isn't it? That's
totally Linux specific. Perhaps you could send a patch to the autoconf
machinery to remove the libaio requirement on non-Linux?

Ian.
