Aló Felipe.
To tell Emacs Org mode that you want a .pdf, customize the
"org-latex-pdf-process" variable.
I usually do it from the export menu: C-c C-e l p (export, latex,
pdf).
To do so, do, visit: [[help:org-latex-pdf-process]] and click
the "customize" link. Near the name, you will see a "Value Menu"
buttom, it has latexmk there.
I still never customized that export, thanks a lot for the
information (emacs and orgmode depth and power never cease to
amaze me).
I will investigate the difference between the standard 3 runs of
latex and latexmk. Of course, any experience about this will be
gratefully enjoyed. :)
Best regards...
