I installed bibtopic and made the script on Herbert Voss's website, following
all other instructions there (put it in ~/bin, set permissions, checked the
path, etc.). But my documents came out with nothing by way of a bibliography,
and citations were empty.
Thinking that perhaps there was still a problem with the path, so that
/usr/bin/bibtex was being run rather than my script,
I put the script into /usr/bin/ and called it bibtex. I renamed bibtex to
bibtex-system, and edited the script to reflect the change--just to eliminate
possible problems with path.
Permissions still seem correct--all files are world-executable.
Just for good measure I ran reconfigure and restarted.
However, LyX simply does not run bibtex. I can put my old \bibliography stuff
back in, removing all references to bibtopic stuff, and LyX shows that it is
running bibtex. But as soon as I \usepackage{bibtopic} LyX no longer runs
bibtex at all. Any idea what the problem could be?
