I have been using LyX with no problems for years, but now suddenly . . .
A paper is already 40 pages long, and has about 90 labels, with
many cross-references. Just today, when I look at a PDF output, the
cross-references are gone, only ?? shows in the PDF, for each
cross-reference.
This is about internal cross-references, not bibliographic references.
All the labels and cross-references do show up okay in the paper and
in the left window.
Any suggestions?
First, look at the LaTeX log, under Document> LaTeX Log. This can be
hard to wade through, but there is probably an error message in there
somewhere.
Alternatively, bisect. Make a copy of the file to work on. Delete the
first half of the body. If that still causes the problem, delete some
more. If it's OK, restore what you deleted and delete something else.
Keep going until you isolate the problem.
I will guess that one of your labels is somehow invalid, and that this
is corrupting the generation of cross-references.
