[dpdk-dev] ConnectX4 100GbE - Compilation problem

[george....@gmail.com]

Hi,

I have a single port Mellanox ConnectX 4 100GbE NIC and I want to test its
Rx/Tx capabilites  using DPDK.
My system runs a Linux kernel 4.4 compiled from sources.

I found the PMD driver for this NIC as provided by Mellanox here

. 
Following this

guideline, I put my NIC in Ethernet mode, configured the 3 options
regarding mlx5 in the config/common_linuxapp file and applied 'make install
T=x86_64-native-linuxapp-gcc'.

Then, I stumbled upon a compilation problem in the mlx4 module.
The compiler's output is as follows:

Iwould appreciate any suggestions and guidance.

Hi Adrien,

Thanks for the prompt reply!
You are right, I didn't go via the DPDK route, in the hope that Mellanox
will provide the exact source and configuration.
DPDK 16.07 from dpdk.org works like a charm and my NIC is in PMD mode,
thanks a lot for your guidance!

Best regards,
Georgios
