Arithmetic overflow error with inline latex

[zorgick]

It seems that org-fc cannot process inline LaTeX with $ notation. The version of emacs is 29.1. Run on wsl2.

Even after disabling latex preview with a file header, it gives the following error:

Debugger shows, that it finds the position of the id in file, however later it still falls with the "ID" error:

Is the same card working if you remove the latex code?

[zorgick]

Yes, without the latex code everything works.

Even after disabling latex preview with a file header, it gives the following error:

ID 2dbbe7ab-3367-47fe-91f1-d4418666fdf7 not found in ~/Documents/notes/src/test.org

It should be noted, that this startup header is ignored, when the buffer is narrowed to the subtree

I've tried the heading you posted in my emacs/org-fc setup and I can review the card and the latex is rendered correctly. For reference, I'm using org 9.6.8 and Emacs 30.0.50.

The difference in the Emacs versions seems unlikely to cause any problems, what's your org version? (M-x org-version)

In the example you posted, the first headline of the file is at level 3 *** Test, does changing it to * Test fix the problem?

[zorgick]

My org version is 9.6.9.

I will try this card on my linux machine and share results in 10 minutes

[zorgick]

Yep, everything is working. I installed fresh texlive-latex-extra (Ubuntu 22.02), and it shows the card as expected.

I believe, the problem is in system dependencies (on wsl I have Ubuntu 20 with texlive-latex-extra installed).

I will close this issue, but only after I manage to solve it on WSL. So bear with me a little bit.

[l3kn]

No worries, it will be useful to have a description of this error and possible solutions in case someone else runs into it.

[zorgick]

Hi! A quick update on the problem. I managed to solve it. The problem was in the emacs build, specifically in --with-pgtk option, that I used to build emacs from source. If I use X window system --with-x-toolkit=gtk3 (default), then latex previews are created and displayed correctly.

[l3kn]

That's good to hear!

Is this issue resolved then?

[zorgick]

Yes, but I still sometimes encounter such problem as:

ID 2dbbe7ab-3367-47fe-91f1-d4418666fdf7 not found in ~/Documents/notes/src/test.org

But as for the topic of the issue, everything works.

[l3kn]

Feel free to open up a new issue if the aforementioned error keeps occurring. If you're using the org-fc-cache, that might be the cause of this problem. It also might happen when trying to review a file that was edited in Emacs but not saved.
