#178 TeXMaths outputs "LaTeX Error: File `article.cls' not found"

[Cbhihe]

Hello:
I saw other tickets on this subject but none of the suggested solutions worked for me.

The host is an up to date Arch linux running kernel 6.7.0, Writer v.7.6.4.1 (X86_64) / LibreOffice Community Build ID: 60(Build:1) with the TeXMaths v0.52 extension.
Trying to insert any LaTeX object (inline or otherwise), e.g. \left( hello \right), I get the following log file error:

This is pdfTeX, Version 3.141592653-2.6-1.40.25 (TeX Live 2023/Arch Linux) (preloaded format=latex 2023.9.17) 23 JAN 2024 15:23

I have restarted LO with a new ~/.config/libreoffice/4/user profile but the problem does not go away.
I also made sure that dvisvgm is installed and so are texlive-basic and texlive-bin.

TeXMaths v0.49 and prior worked for me in the past.
Any pointers would be very welcome. Thank you.

Hi, this sounds like your system uses pdftex instead of latex for compiling.
Could you try this:

cd ~/.config/libreoffice/4/user/TexMaths/tmp
latex tmpfile.tex

This should compile the last entered equation and give a valid tmpfile.dvi.

[Cbhihe]

Hi Roland ! Thank you for your response and sorry for my late reply. I understand your suggestion is a manual workaround to the issue I have but essentially it does not fix my issue, meaning that it does not make my LO Weriter + plugin usable.

Would you be so kind as to suggest something so I can get my plugin to behave as expected ?
For instance would trying to get latex to compile instead of pdftex be part of your suggestion ? If so how should I go about this ?

In the meantime, I have gone from Archlinux 6.7.0 to 6.7.3-arch1.1
and I now work with LibreOffice v24.2.0.3 (X86_64) / LibreOffice Community Build ID: 420(Build:3) - Locale: ga-IE (en_US.UTF-8); UI: en-US
and with TexMaths 0.52-1.

Thank you.

[Roland Baudin]

Sorry, I was not clear: the command I gave you was for test purpose. Did it work?
Could you send me a screenshot of your TexMaths configuration?

[Cbhihe]

Ok, thank you. Here is the result of your suggestion:

Hee are the TexMaths preferences (1 screen shot).
For its config, I have under "Paths"
/usr/bin/latex
/usr/bin/xelatex
/usr/bin/dvilualatex
/usr/bindvipng
/usr/bin/dvisvgm
... all correctly installed and referenced as above.

I have under "Options"
Compiler: Latex
Equation caption: Equation
Numbering level: 1

[Roland Baudin]

Ok, thanks for these informations.

First, the LaTeX code for your equation is not correct. The correct code is:
\left[ x(t) = A(t) \times \cos (\omega t ) \right] ('times' instead of 'time' and '\cos' instead of 'cos').

Then, the output of the latex command should be something like this:

So, you probably have some LaTeX configuration issue in your system. Note that TexMaths calls the latex command to produce a DVI file.

I suggest your reinstall texlive on your system and check that the latex command produces a DVI file.

Note that the screenshot I need to check the TexMaths configuration is the one from the TexMaths configuration dialog (button with the gear icon).

[Cbhihe]

Roland,
Per your suggestion I uninstalled texlive-basic and libreoffice-extension-texmaths, both from the Archlinux extra repo. Upon reinstalling them (sudo pacman -S texlive-basic libreoffice-extension-texmaths) i was given the possibility to install further texlive related packages, eg. texlive-plaingeneric, texlive-binextra, texlive-context, texlive-fontutils, texlive-latex, texlive-mathscience and a few others.

I re-installed all of the above and now the TeXmaths extension in LO is back to normal.

I surmise that somehow this host's LaTeX installation was tempered with. Hence the disruption I experienced.

Thank you very much for your help!
TICKET CLOSED.

Hi, nice to hear it works now!
