spdk / dpdk Goto Github PK

I thought this was the canonical repository until i noticed the 3-year old timestamp on the latest commit. It would save time for a lot of people if the move to the own git repo hosting was documented in the README here. I can provide a PR for that if you like?

SPDK v19.04.1 makes reference to:

DPDK
Added DPDK 19.05 support.

But I don't see any 19.05 release here. Latest seems to be v18.08. Is dpdk behind on making some releases?

Getting following error while building librte_eal for dpdk -

I believe this is due to an incompatibility with the linker but I couldn't find any such error on the internet. Can anyone please explain how to resolve this or even what this error means?
