[Qemu-devel] [PATCH 11/12] include core qdev code into *-user, too

[Qemu-devel] [PATCH 11/12] include core qdev code into *-user, too |
|
Date: |
Tue, 16 Oct 2012 03:57:23 +0200 |
From: Eduardo Habkost <address@hidden>
The code depends on some functions from qemu-option.o, so add
qemu-option.o to universal-obj-y to make sure it's included.
Signed-off-by: Eduardo Habkost <address@hidden>
