I'm using Ubuntu 19.04 and Emacs 26.1. Whenever I try to use inline preview (with any region, section, or environment that has inline math), I get the following error:
... TeX Output exited as expected with code 1 at Mon May 13 20:01:20 Running `Preview-PDF2DSC' with ``pdf2dsc _region_.pdf _region_.prv/tmpQWkzKT/preview.dsc'' Preview-PDF2DSC killed at Mon May 13 20:01:20 LaTeX: Wrong type argument: number-or-marker-p, nil
and the preview job quits. When I enable debugging, with
M-x toggle-debug-on-error, I get the following output:
Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil) signal(wrong-type-argument (number-or-marker-p nil)) preview-reraise-error(#<process Preview-LaTeX>) preview-TeX-inline-sentinel(#<process Preview-LaTeX> "Preview-LaTeX") TeX-command-sentinel(#<process Preview-LaTeX> "exited abnormally with code 1\n")
I've tried the answer posted in this link but my
preview-gs-command variable is already set to
usr/bin/gs, which I think is sufficient.
Please let me know where I can find a fix to this.
