[O] [BUG] org-create-formula-image requires 'gs' when it doesn't look like to be necessary (causing issues on Windows)

[Frederick Giasson]

Hi,


I am a Windows user and I am testing the Org 9.x branch. I just 
discovered that I couldn't display inline latex anymore using C-c C-x 
C-l. I was getting that error:


    org-create-formula-image: Can’t find ‘gs’ (you need to install the 
programs: latex, dvipng and ghostscript.)


A look at orl.el line #4079: "(defcustom 
org-preview-latex-process-alist", for "dvipng" we have a programs list: 
"("latex" "dvipng" "gs")"

The problem here is that "gs" is not an executable that exists in 
Ghostscript for Windows nor I think it is necessary for that to work.

I did remove it from the list of required parameters, then I restarted 
Emacs and everything is working fine now.


Any thoughts on that? Should it be fixed? (I guess)


Thanks,

Fred
