Trying to use Emacs for note-taking and organization (org-mode) and in the process trying to figure out how to export to pdf via texlive. However, living in Europe, getting pdf-outputs in the Letter format is tedious, and I would like to setup texlive to generate an A4.
But how?
Hope this is the right forum for the question, or else, that there might be someone to point me to the right place.
Can't help you much with emacs. Does it generate a LaTeX source file that you process with pdf TeX into the PDF?
Texlive has several TeX processors included. It is a distribution of TeX related software, much like Ubuntu is a distribution of Gnu/Linux related software.
If you are generating a LaTeX file, there is a /documentclass[12pt,letterpaper]{article} statement near the top. Change letterpaper to a4paper and that's it. Yours may say report or book in place an article. Just leave that at whatever it says.
If emacs is directly generating a TeX file or if you have other information about exactly which parts of Texlive you're using, let us know.
