Re: [dpdk-users] Building mlx5 with rdma-core/OFED

[Gerry Wan <gerryw@stanford.edu>]

How did you install these packages? Are there extra environment variables I
need to set?
After running the OFED uninstall script,

apt-get install rdma-core
apt-get install libibverbs-dev

both work fine, but ninja install now fails on
