There are only few stubdoms you can build without the Xen tree. How
would you do so for e.g. xenstore-stubdom needing the Xenstore sources
to be built? Several stubdoms need libxc built for stubdom included.
And you want to have a build error if e.g. a libxc modification is
breaking stubdom build.

Hi,

Raisin already builds xen too, so it has all the dependencies ready. Regarding the problem of breaking stubdom build by libxc changes I think those can be prevented if we introduce osstests for raisin build. Maybe we should start with that, adding raisin to the osstest framework.

Opinions?

Cheers
