[Qemu-discuss] Make problem on migration-rdma.o

[Nicholas Taylor]

I just solved this problem at work.
I was building qemu 2.0 on an ubuntu 12.04 machine.

This error says there is a variable "link_layer" is missing
in the struct "ibv_port_attr"
That struct exists in the file /usr/include/infiniband/verbs.h.

Your version of that file is older than qemu likes.
In ubuntu that file is managed by the package "libibverbs-dev"

http://packages.ubuntu.com/pt/trusty/libibverbs-dev

If you build and install this package before building
qemu your problem should be solved.
