[dpdk-dev] Warnings when building the doc on Ubuntu 18.04

[David Marchand]

Hello,

I tried to build the documentation but it looks like the instructions
about how to build it are not up to date. Currently running Ubuntu
18.04, it might be the reason.

So I installed the latexmk package.
Nothing in the dpdk refers to it, so it might be an external issue.


After this, I still see those warnings (and actually a lot of others).
The pdf generated docs have no link in them, but the html ones are fine.
Is is expected ?
