Oops, sorry I was vague.

What I normally do is to stay in top level directory of the source tree,
run ./configure and then run make -- stubdom should be built by default.
But the C stubdom is not built by default. :-/

So in order to build c-stubdom, you need to enter stubdom directory and
run ./configure --enable-c-stubdom. You should see in the output
c-stubdom will be built.

Stubdom is mini-os + libc + all other libraries your application needs.
Yes, it's going to be an exercise. You need to wire up stubdom's
Makefile. There are existing examples in stubdom. You can try your luck.

Another way to achieve your goal is to try "rump kernel". It's still
under development but the build system is a bit nicer to work with than
our in-tree stubdom build system IMHO.

Both solutions will require some work. I can't tell for sure how much
work is required.

One thing to note is that mini-os has been extracted to an external tree
in xen-unstable. The build system will clone it on the fly. It's
supposed to work out-of-box but in case you have problem you at least
have a clue about what is going on.

No they are not general obvious. No need to be sorry.
