[ovs-discuss] openvswitch 1.2.2 on RHEL 6.2 : make failed

[Benoit ML]

Hello,

Thank you a lot !
You wil  get rid of a niggling problem :)

Well sorry I didn't know why I tell you 1.3.0 compile ... Obvisouly
this is not  the case (attached log)  (perhaps I've missed the first
line).


Thx !

Regards,
