Any way for this to be made to work with GD2 instead of Imagemagick? Most of us on shared servers aren't able to use this mod because of that. Imagemagick takes up a lot more memory and resources, GD2 is what is typically found on shared servers.

Will consider it. No promises.

But I'd say that hosts that are willing to install latex, which is not very well known for hosting managers, would have much less problems installing imagemagick.

How about the update? Can´t wait ;P

I can test it on the latest vB Version and let you know if it works without problems.

Are you willing to beta test the mod before release? If so, PM me and I'll send it to you.

is there any progress with the mode update?

thanks for the update, buy yet i get this errors :

[LaTeX ERROR: Convert failed]

and in the error log file :

Looks like latex isn't generating the dvi file, but it's not raising any error at that stage so the error appears in a later phase (dvips and convert). That's strange since the latex compilation phase didn't have any change in this last update. I assume it was working for you earlier, which makes it even more strange.

To troubleshot this, let's try to reproduce manually all the commands that the mod issues.

Please, do something like this:

1. Log in ssh to your server
2. cd to the vlatex/temp directory
3. Make sure that the directory is almost empty (there should be only a index.htm file; if some temporary file wasn't properly deleted it should be safe to delete it now).
4. Create a test.tex file with the following contents (for instance, do it with nano test.tex)

Code:

\documentclass[10pt]{article}

\usepackage[latin1]{inputenc}

\usepackage{amsmath}

\usepackage{amsfonts}

\usepackage{amssymb}



\let\dst=\displaystyle

\newcommand{\dd}{\mathrm{d}}

\newcommand{\ee}{\mathrm{e}}

\newcommand{\eee}[1]{\mathrm{e}^{#1}}\pagestyle{empty}

\newlength{\formuladepth}

\newsavebox{\formulabox}

\begin{lrbox}{\formulabox}

$E = m c^2$

\end{lrbox}

\settodepth{\formuladepth}{\usebox{\formulabox}}

\newwrite\opdepth

\immediate\openout\opdepth=\jobname.depth

\immediate\write\opdepth{\the\formuladepth}

\closeout\opdepth

\begin{document}

\usebox{\formulabox}

\end{document}

5. Compile the test file with

Code:

latex --interaction=nonstopmode test.tex

6. Please, report back tell me any error that appears after doing that. Report back also the list of files in the directory after that operation (that is, copy into the forum the result of "ls -l" after running step 5).

Feel free to send me the results via PM if you don't want to post that information to the wild :D

actually i didnt use this mode before, ive just installed all needed programs today.

after step5 i get in the end : No file test.aux.

ive sent you the test.log file on private .

ls -l gives :

Everything looks ok (the absence of the aux file is not a problem, it only means that it's the first time you compile that latex file).

Right now, my best bet would be a permission problem. Please, make sure that the web server can write to vlatex/temp and vlatex/pics. That usually means chmod them to 777.

Please try that. If not, we'll try other tests :D
