LyX ⇒ Help: TeX capacity exceeded [grouping levels]

[Blaazen]

Hello,

I need help with following error: TeX capacity exceeded, sorry [grouping levels=255] (or 80000, or 100000, depends if I use pdflatex, LuaTex, ps2pdf or so). I guess it is more related to changes in Lyx (or packages), because I tried 2 years old backup of my document and I get this error too although I'm sure that conversion to pdf worked well at that time.

My Lyx: 2.3.0, OS Linux Chakra 64-bit, Qt 5.10.1, texlive-langgreek 2017.46662-1 (from Arch Linux repository).

If you really absolutely need more capacity,
you can ask a wizard to enlarge me.

 
Here is how much of TeX's memory you used:
 3337 strings out of 492990

 5935 words of font info for 17 fonts, out of 8000000 for 9000
 1141 hyphenation exceptions out of 8191
 26i,1n,43p,462b,630s stack positions out of 5000i,500n,10000p,200000b,80000s
!  ==> Fatal error occurred, no output PDF file produced!

Line 57 of my lyx file is:
56 \use_bibtopic false
57 \use_indices false
58 \paperorientation portrait

IMO I don't have anything special in my document, mainly text, tables, toc.

Thanks for help, if you need more info, let me know.

Hi Vojtěch,

welcome to the forum!

Can you perhaps make a pdfLaTeX export in LyX, and post it here? At least until the \maketitle line.

Stefan

[Blaazen]

Thanks for reply.

I got the same error if I use preview (Ctrl+R) or File -> Export -> pdflatex.

The log is the same as in my first post.

[Stefan Kottwitz]

Export to pdfLaTeX doesn't produce a PDF and cannot bring the error. I'd like to se the exported .tex file.

I understand. This is snippet from beggining to \maketitle. Whole tex file has 40kB and ~1700 lines.

Very good! Now I can test it and could reproduce the error and test the fix. In this export, we see that LyX already defined \makesavenoteenv{tabular}, seen in line 16 of the export. As you added it to the preamble yourself too, seen in line 47 of the export, it's called twice and that causes the error, this double modification. Just remove it from your document preamble.

Stefan

[Blaazen]

Yes, it works now! Thank you very much!
