[ovs-discuss] Error - build kernel module (openvswitch-2.0.0.tar.gz) on RHEL 7 Beta

Mon Dec 30 18:46:08 UTC 2013

I was trying to build the Open vSwitch kernel module(using openvswitch-2.0.0.tar.gz<http://openvswitch.org/releases/openvswitch-2.0.0.tar.gz>) on RHEL 7 Beta .
My kernel version is 3.10.0-54.0.1.el7.x86_64 .

rpmbuild -bb  -D "kversion 3.10.0-54.0.1.el7.x86_64" -D "kflavors default debug kdump"  rhel/openvswitch-kmod-rhel6.spec

I get the following error when the above command is executed -
