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

Tue Feb 20 10:18:42 UTC 2018

Looks like you didn't install MLNX_OFED ir something wrong with your installation, the following file is missing: 
/usr/include/infiniband/mlx5_hw.h

What OFED did you install and how?

Thank you Olga
What I'm trying to do is to run ovs-dpdk w connectx4 card, I don't care about the versions but only try to  find a  combination of versions (dpdk/ovs/kernel) that is working.
As you've suggested,  now I'm working with dpdk.17.05 (ovs 2.8.1) .
I'm following the https://emea01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fdpdk.org%2Fdoc%2Fguides-17.05%2Fnics%2Fmlx5.html&data=02%7C01%7Colgas%40mellanox.com%7C452a99fe115941a1fd0508d5783add13%7Ca652971c7d2e4d9ba6a4d149256f461b%7C0%7C0%7C636547116571396518&sdata=YyijRGomnVwvz8epD90ec1lx4YyB2Fn2InZvgK5fqfY%3D&reserved=0
And I have compilation error when building dpdk  - [ note that  dpdk 18.02 and dpdk.17.11 build pass ok, but then ovs failed with undefined mlx ref.]

Dpdk.17.05 - compilation error:
--------------
In file included from /home/avi/dpdk-stable-17.05.2/drivers/net/mlx5/mlx5.h:68:0,

/home/avi/dpdk-stable-17.05.2/drivers/net/mlx5/mlx5_rxtx.h:46:32: fatal error: infiniband/mlx5_hw.h: No such file or directory
