Thanks for the response. I knew one has to run pdflatex twice (when any of the links change) and should have put that in my report above. I did not know three times was necessary in some cases. Unfortunately, this does not fix the problem; i.e., the following
rm -r _build
sphinx-build -b latex . _build/latex
cd _build/latex
pdflatex <project_value>.tex
pdflatex <project_value>.tex
pdflatex <project_value>.tex
has the same result
No file <project_value>.ind
in the file file
_build/latex/<project_value>.log
and the index is not in the file
_build/latex/<project_value>.pdf
I added the
rm -r _build
because you must first delete the old _build directory to test this. If you don't, the old <project_value>.ind file from the previous
make latexpdf
gets used by the
pdflatex <project_value>.tex
command.
