Bug report: Nomenclature no longer works on LyX 2.4.0 beta 5

[Léo de Souza]

Hi,

I would like to report that the nomenclature function no longer works for me on LyX 2.4.0 beta 5.

Environment:

I compiled LyX 2.4.0 beta 5 on Ubuntu 22.04 with Qt6 enabled and my Tex Live install is up to date.

Steps to reproduce:

1. Create new document: File > New
2. Insert nomenclature entry: Insert > Nomenclature Entry...
3. Insert nomenclature: Insert > List/Contents/References > Nomenclature
4. View document: Document > View [PDF (pdflatex)]

Expected result (LyX 2.3.6): The output PDF contains a nomenclature.

Actual result (LyX 2.4.0 beta 5): The output PDF does not contain a nomenclature.

Additional comment: Saving a file that works in LyX 2.3.6 and opening it from LyX 2.4.0 beta 5 also doesn't work.
