In pkg/dpdk.spec, there is this requirement (for RedHat based distro):
	doxygen, python-sphinx, inkscape, texlive-collection-latexextra
I am not sure it is up to date though.

There is also a guide listing the dependencies:
	doc/guides/contributing/documentation.rst
Here, it is mentioned
	TexLive (at least TexLive-core and the extra Latex support)
and
	# Ubuntu/Debian.
	sudo apt-get -y install texlive-latex-extra

Is it enough? Or is there a miss?

Is latexmk a dependency of texlive-latex-extra?

The warnings are about the cross-doc links.
I think links are working inside a PDF but obviously not when referencing
another PDF document.
Do you see a different issue?
