# org-mode render latex fragments without using cache

How do I disable caching behavior when using C-c C-x C-l and C-u C-u C-c C-x C-l? I want the ability to force org-mode -> pdfTex to rerender everything in the current file from scratch.

Here's some more context about what exactly I'm doing and what the motivation is.

I have a setupfile for notes that consists of a whole bunch of LaTeX header lines.

#+SETUPFILE: ./setupfile.org


Here's a few lines of the setupfile that give a sense of what's in it.

#+LATEX_HEADER: \usepackage{alphabeta}

Whenever I make a new definition or define a new abbreviation, I put it in the shared file. Unfortunately, when I rerender everything (C-c C-c and then C-u C-u C-c C-x C-l), there's some caching going on and I can't actually see the effects of my change.
• Just delete the images in the sub-folder ltximg. I.e., M-! rm -f ltximg/*. Afterwards recreate the images with org-toggle-latex-fragment. – Tobias Jun 30 '17 at 7:32
