[ovs-discuss] OvS build (w DPDK) failed - Undefined Mellanox references

Avi, 

Every DPDK version has specific MLNX_OFED that is supports:
If you will follow the instruction that I sent to you will see that:
Mellanox OFED version should be  4.0-2.0.0.0 and installation should be   ./mlnxofedinstall 
http://dpdk.org/doc/guides-17.05/nics/mlx5.html 

Now, you can stay with MLNX_OFED 4.2, but you will need to reinstall  it without --upstream-libs flags.

Starting DPDK 17.11 Mellanox PMDs supports upstream rdma-core libs, therefore the installation is different for DPDK versions starting 17.11
Since user shouldn't be aware about this info, user should follow the exact instructions!

Best Regards,
Olga

Olga

I have OFED -  MLNX_OFED_LINUX-4.2-1.2.0.0-ubuntu16.04-x86_64
I install it like this :  ./mlnxofedinstall --force --dpdk --upstream-libs NOTE  that I don't have this problem with dpdk.17.11/ dpdk.18.02

Best Regards
Avi
