I am trying to use the Lua script “selection_to_pdf” to create an overview of an image selection as a PDF file.
Unfortunately I can’t get along with it, because it gives error messages.
I use Arch Linux and darktable 3.8.0, xdg-open 1.1.3 and pdflatex shows the following version information:
$ pdflatex --version
pdfTeX 3.141592653-2.6-1.40.23 (TeX Live 2021/Arch Linux)

I have selected 10 images in the lighttable and specified “Export thumbnails to pdf” as the destination file in the export module. I specified a title and a filename with save path.
When I click on ‘export’ I can see that the selected images are exported. At the end the message ‘problem running pdflatex’ appears briefly in darktable. In the output of the terminal I see the following message:
This is pdfTeX, Version 3.141592653-2.6-1.40.23 (TeX Live 2021/Arch Linux) (preloaded format=pdflatex)

If I select only one image in the lighttable and start the export with the same settings it works. A PDF is created with a thumbnail, but in portrait format and not in landscape format as specified in the export.
Probably I just don’t understand how to use the module correctly. Maybe one of you has a hint for me? Is the version of pdflatex wrong?
