Hi guys,

I had to roll back OFED version from 5.0 to 4.4 because another library
Moongen has trouble building with OFED 5.0. I rolled back the version and
Moongen builds and when I try to build dpdk 18.11, 19.11,17.11. All the
three builds fail with the following error (https://pastebin.com/fiw7iz1Z
Link of build error). Does anyone know why this happens. I am exhausted
with roll backs,if anyone can help me with this I would be grateful. , By
the looks of it, it might mean it had problems with the OFED driver? I
installed the MLNX ofed driver without any flags, i.e ./mlnxofedinstall. If
you want any further information,please let me know. Any suggestion would
be appreciated, even if you don't think it might work. I have been trying
to install these two for the past week, without much success. Are the above
mentioned DPDK version not compatible with said driver(4.4)?

How Moongen is related to OFED?
Why using OFED and not upstream packaging of rdma-core?
Which distribution are you using?

Any DPDK version should build with any version of OFED or rdma-core.
Note: DPDK 17.11 is not supported anymore.

Let's focus on your goal and see what is the real issue you hit.
Which version of DPDK do you need?
Why not start with the latest LTS, which is 19.11?

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.

Do you have a link to TAS? I don't know it.

So your only issue is to install Moongen,
given you already have DPDK working.

No, Moongen requires only DPDK.
If I am wrong, please could you show where you found such info?

Installing the Ubuntu package rdma-core should be enough.

You are mixing different versions of drivers.
Choose either rdma-core packaged in Ubuntu,
or OFED from mellanox.com.
