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

Hi again,
There is one thing I forgot to mention: PDF/LateX export was working fine.
Thanks,
Fred

Do you mean that "gs" could be removed from all entries in
`org-preview-latex-process-alist'?
I'm Cc'ing Feng Shu, who implemented the new LaTeX preview mechanism. He
hopefully knows why this dependency was introduced in the first place.

I think so yes, at least on Windows (didn't try on Linux nor OSX)
Thanks,

I've checked all three converters on os x as well (but not linux). ghostscript
is included an a dependency for all of them, so won't work on osx w/o
explicitly installing ghostscript, but in fact, work fine w/o it. I am not
sure why it has been set for each converter as a dependency since it does not
seem to be used by any of the conversion chains. As an aside, it is not
mentioned in the documentation (info).

Fair enough. I removed the dependency.
