[Qemu-devel] [PATCH 2/3] configure: Default to enable module build |
Date: |
Mon, 12 Jan 2015 12:43:10 +0800 |
We have module build support around for a while, but also had it bitrot
several times. It probably makes sense to enable it by default so that
people can notice and use it.
Counterpart to --enable-modules, which is turned as default,
--disable-modules is added to suppress it. If both are omitted, the
support is guesses as usual.
