The main problem is not 'environment
out of the box' but the exact versions of libraries, compilers and
so on. Because xapi-libs heavily depends on random set of
libraries outside the xapi source tree, and there is no way to
know witch version to use. Sometimes there is a situation that
xapi depends on library foo and bar, and foo (in upstream) depends
on different (conflicting) version of bar. And it definitively not
compilable on centos5 (because of outdated ocaml for el5)...
To be honest I was strong supporter for xapi. But time flows - XCP
0.5, XCP 1.1, XCP 1.5, XCP 1.6. Every time we found an working ISO
with working binaries we can use like 'free version of XenServer'.
But no any modification of code was possible (no way to build
original ISO, or, at least, original xapi's RPM). That was
definitively not a 'free as freedom', just 'open source'. Some
minor stuff in /etc/xensource/scripts and /opt/xensource/sm with
patches, but no any significant changes was possible. We actually
have a huge (over 3k lines) code which simply doing stuff 'around'
xapi instead adding that functions to original code.
Now we got XCP 1.6. Again there is a significant set of changes we
want to add (and share with others!) - but we can't, and we
continue to add 'hacks around'. Really, I not very happy about
this and start to thinking about switching to something more 'free
as freedom' visualization stack.
Lack of 'scrach your own itch' is very and very disappointing. I
really don't want to switch away from xapi and want to see some
cooperation...

Details of build environment are closed and without that
information disclose you can assume XCP is not opensource, but
just 'free'. (sad).
We
know this isn’t ideal but we’re working on fixing it at the
moment. Reproducing the Citrix build environment isn’t
practical so we’re making XCP/XenServer buildable in a more
standard environment. More on this soon.

We've tried few times, but gave up.

To be precise: you can build xapi sources from git, but in
very strange environment with unknown version of
libraries. It will be 'some binary', not the original
XCP's xapi.

And are there any instructions about
compiling XCP/XAPI?
