Disable all the other extensions except for LaTeX Workshop, and check that you still see this issue. [Required]

You still see this issue?: Yes

Make sure to visit the wiki FAQ before filling an issue.

You visited the wiki?: Yes

If your issue is with compiling a document (not having to do with finding the root file of a project), check first that you can compile manually.

You can compile a TeX document manually?: Yes

Describe the bug [Required]

The file is not compiled on any file change.

To Reproduce

Steps to reproduce the behavior:

1. Run latexmk w/ repeat recipe
2. Write any text
3. Nothing updates

Expected behavior

I expect that there would be build processing.

This is kinda awkward, but it works now??? 🤣

Not sure what was the reason, but I have added

"latex-workshop.latex.watch.usePolling": true,
"latex-workshop.latex.autoBuild.run": "onFileChange",

to the settings. Maybe WSL2 wants that usePolling? I am also using WSL2 now, 2 months back I have been using WSL1, so maybe WSL2 needs this rule?

---

I have opt out the "latex-workshop.latex.watch.usePolling": true, and it doesn't work without it in WSL2.

It would be great to add this to the wiki next to https://github.com/James-Yu/LaTeX-Workshop/wiki/FAQ#using-latex-workshop-with-wsl! :-)

[tamuratak]

It might be related to microsoft/WSL/issues/4739. Another workaround seems to be moving TeX files from d:\git to the Linux filesystem.

[jlelong]

@tenhobi could you make a PR to https://github.com/jlelong/LaTeX-Workshop-wiki with the correct configuration for WSL2?

[tenhobi]

@tamuratak thanks for pointing to that issue. That is for sure related.

@jlelong done. 😸
