I am using Libvirt-1.0.0 on ubuntu 14.02 LTS and found the following error

"checking linux/if_bridge.h usability... no
checking linux/if_bridge.h presence... yes
configure: WARNING: linux/if_bridge.h: present but cannot be compiled
configure: WARNING: linux/if_bridge.h:     check for missing prerequisite

configure: WARNING:     ## ------------------------------------- ##

Please Guide, how do I recover it
