Can't get dvipng to work

Can't get dvipng to work

[Williams, Ken]

[-- Attachment #1: Type: text/plain, Size: 1425 bytes --]

Hi,

I have a small orgmode document with a \begin{align} section for a few equations.  I can successfully export to HTML using MathJax, but I need a nice little self-contained document, so I'm trying to use dvipng.  Unfortunately it keeps exporting with MathJax.

Here's my document:

=========================================
#+TITLE: Test Doc
#+AUTHOR: Ken Williams
#+PROPERTY: results output
#+PROPERTY: exports both
#+OPTIONS: tex:dvipng

Some math:

\begin{align}
a_{11}& =b_{11}&
a_{12}& =b_{12}\\
a_{21}& =b_{21}&
a_{22}& =b_{22}+c_{22}
\end{align}
=========================================

The value of my "org-latex-create-formula-image-program" variable is dvipng - I set it manually from within the editor by doing "set-variable org-latex-create-formula-image-program dvipng".

Any hints?  There are no clues in the *Messages* buffer.

My org-mode is Org-mode version 7.9.4.

Hi Ken,

So in short I think the easiest course of action is upgrading to the
newest release, e.g. using ELPA (M-x list-packages).

I cannot reproduce using emacs -q.

Does it work as expected when you try from emacs -q?

Are you using the new exporter?  It's named ox now, but it might be
org-export in your version.  In v8 you'd need to require ox-html.

Have you tried your document with v8?

Do you have dvipng installed?  I install it via texlive, e.g.

   tlmgr install dvipng

Mine is: 

Org-mode version 8.1.2 (release_8.1.2 @
/usr/share/emacs/site-lisp/org/)

I agree - I'm trying to update now.  I hadn't used ELPA before, so I tried 
that route and I'm getting a ton of 'ox-*' related errors like this:

I can try installing manually but it would be great if I could get ELPA 
working.

So I installed org-8.1.2 manually and now it does seem to be *trying* to 
process the images through LaTeX.  But it's not succeeding.  In the *Messages* 
buffer, I see this:

--------------------
Creating LaTeX Image...

c:/Users/KWILLI~1/AppData/Local/Temp/orgtex6488Qq2.tex

I pasted the contents of ~/AppData/Local/Temp/orgtex6488Qq2.log here, but I 
don't see anything strange in it:

What happens if you run latex on the tex file by hand?

On Linux, I would say

   cd .../Local/Temp
   latex orgtex6488Qq2.tex

I presume something similar would work on Windows.

It succeeds: 

 % latex orgtex6488Qq2.tex
 ...
 Output written on orgtex6488Qq2.dvi (1 page, 1304 bytes).
 Transcript written on orgtex6488Qq2.log.

Additionally, if I run pdflatex manually on the tex file, the output is 
sensible.

I don't know how to verify that the tex/latex Emacs is running is the same as 
the one I get at the command line - nor whether the failure is during 
tex/latex or during dvipng.

Then try to run dvipng FILE.dvi or perhaps just dvipng FILE.  Does
this work?

Yes, it produces a proper output PNG that looks good, but note that the base 
filename has a '1' appended:

% dvipng orgtex6488Qq2.dvi
This is dvipng 1.14 Copyright 2002-2010 Jan-Ake Larsson

This would probably be a lot easier to debug if the emacs logs included the 
command line strings that are being run.

That's weird, but I can reproduce it here.  It's follows from the
manpage

 -o name
     Send output to the file name. A single occurrence of %d or
     %01d, ..., %09d will be exchanged for the physical page
     number (this can be changed, see the --dvinum switch). The
     default output filename is file%d.png where the input DVI
     file was file.dvi.

This is untested, but try to do:

C-h f org-create-formula-image-with-dvipng

click on org.el link

with the cursor on the within the defun do
M-x edebug-defun

Create simple document an make Org call dvipng.
