With this v4, mlx4 builds fine in my Ubuntu 20.04.6 container. However, I think the mlx4dv.h includes are probably faulty: as this header is using off_t, it should include sys/types.h in the first place. https://github.com/linux-rdma/rdma-core/blob/master/providers/mlx4/mlx4dv.h#L36 This had been fixed in the mlx5 header in some rdma-core change in the past: https://github.com/linux-rdma/rdma-core/commit/d2389b34ccc5 -- David Marchand
