How did you install the OFED? In order to install the rdma-core libs of OFED (which includes the mlx4dv.h) you should use the following command: ./mlnxofedinstall --dpdk --upstream-libs I guess mlx4 guide is not yet updated for this release. The update for this release should include the new OFED and the command line to install it. > > Thanks, > Mike
