Re: [dpdk-dev] Compilation of MLX5 driver

[Asaf Sinai <AsafSi@Radware.com>]

Hi Shahaf,

I face similar problem with DPDK 18.05, where missing file is "mlx5dv.h":

	== Build drivers/net/mlx5
	  CC mlx5.o
	In file included from /net/emcradware/CM_Users/asafsi/work/drivers/dpdk/dpdk-18.05/drivers/net/mlx5/mlx5.h:35:0,
	                 from /net/emcradware/CM_Users/asafsi/work/drivers/dpdk/dpdk-18.05/drivers/net/mlx5/mlx5.c:40:
	/net/emcradware/CM_Users/asafsi/work/drivers/dpdk/dpdk-18.05/drivers/net/mlx5/mlx5_mr.h:19:31: fatal error: infiniband/mlx5dv.h: No such file or 	directory
	 #include <infiniband/mlx5dv.h>
	                               ^
	compilation terminated.

Can you please advise?

Thanks,
Asaf

Thanks Shahaf, it worked after removing the options you specified.

In v17.05 MLX5 PMD is still relying on libibverbs and libmlx5, the way Those options you used are necessary to select in their package the installation of libverbs,libmlx5 or rdma-core.
Doing this you have selected rdma-core which is not supported in v17.05 DPDK version.

You need to install Mellanox OFED without those two options to select libibverbs, libmlx5 to make it work.
