[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v4 12/15] autoconf: xen: peg the xenstored preference onto the top level config
From: "Luis R. Rodriguez" <mcgrof@xxxxxxxx>
This lets us easily look what xenstored we have on the build system
and use it with autoconf for file generation. Although you can now
specify your preference to disable ocaml tools the we can only make
a general build flag available if coming from the parent configure.ac
You can only use:
./configure --with-xenstored=cxenstored
./configure --with-xenstored=oxenstored
And by default oxenstored will be used, but only if you have ocaml
dependencies. Enabling cxenstored will then disable ocamltools. This lets
us simplify the legacy init script a bit but it should help us simplify
our systemd service files even more.
