Re: [Xen-API] Intel CQM feature enabling in XenAPI

[Bob Ball <bob.ball@xxxxxxxxxx>]

Hi Qiaowei,

This sounds like it could be heading down a rabbit hole, trying to get 
xenserver-core building from XAPI trunk.  If I remember correctly, the current 
issue is that you need to take a newer ocaml-xcp-idl.

I've made a number of changes which I suspect you may need at 
https://github.com/BobBall/xenserver-core/commit/73ad5a198e8a68ab399f8c2a07e440e2fc7121f2.
  Note that these changes are to enable us to build from master of all 
repositories on a daily basis (e.g. the RPM version numbers will contain the 
build date).  If that's not your intention, you may need to modify the patch to 
suit your needs. 

Some of these are to make things build with Ocaml 4.0.1 as XAPI now depends on 
4.1 which is not available in any distribution.

I do not claim that these changes are all that are needed; I have not finished 
my investigations into building from master and I'll be getting back to it soon 
I hope.

Bob
