Hi, folks
I tried to build ovs 2.6.1 in Ubuntu trusty 64 with the below configuration
options, but it failed, it is ok when I use the same way to build in Ubuntu
16.04 which has Linux kernel 4.4. What is the minimum Linux kernel version ovs
2.6.1 build requires?
./configure --prefix=/ --with-linux=/lib/modules/`uname -r`/build
Here is error log
/home/vagrant/ovs-2.6.1-build/ovs-2.6.1/datapath/linux/gso.c: In function
