Hi Thomas,

We want to use TAS which is built on top of DPDK, I installed Mellanox OFED
5.0 and TAS and everything was good, until we had to install Moogen. Please
find my answer to your questions. Thanks for the prompt reply. I appreciate
it.

We are using Ubuntu 18.04. I indeed had success in installing dpdk 19.11
LTS with MLNX_OFED 5.0. To answer your questions about Moongen either
requires 1) Complete OFED drivers or 2) libibverbs, libmlx5,
mlnx-ofed-kernel packages, These packages are installed with MLNX_ofed
drivers if I am not mistaken. So I moved on to build Moongen, When building
moongen with OFED 5.0 I get the error fatal error: infiniband/mlx5_hw.h: No
such file or directory #include <infiniband/mlx5_hw.h>. I thought this
might be related to the libmlx5 and I installed libmlx5.deb from the
packages in the DEBS/ folder. testpmd stops working with this prompt
./testpmd: /usr/lib/libmlx5.so.1: no version information available
(required by ./testpmd). So I tried rolling back the OFED version to 4.4,
which has caused problems with building dpdk with version 19.11 LTS,18.11
LTS and 17.11 LTS as I shared in the previous mail.

I hope this answers your questions.
