Hello all, firstly thanks for the great work on LyX. It is a superb
piece of software.
However, I've encountered a problem when using graphics (i.e. images)
in-conjunction with the grammar environment of the syntax.sty package.
Specifically, if I include both an image and a grammar environment
then the document will fail to compile with Undefined control
sequence errors. What is extremely curious, however, is that if your
export the same file fro LyX to LaTeX (pdflatex) you will then have a
..tex file which compiles perfectly, without error!
Unfortunately, I am not familiar enough with LyX to understand how to
investigate this further. However, if useful, I can certainly follow
instructions to diagnose/debug if pointed in the right direction.
Reproducibility:
- have tested using LyX 2.0.2 on Linux (Ubuntu 10.04), OS X 10.7, and
Windows Vista
- have tested using LyX 2.0.3 on Linux (Ubuntu 10.04)
Steps:
- make an empty document, insert 1 image
- add \usepackage{syntax} to document preamble
- insert lyx code:
\begin{grammar}
hello ::= WORLD
\end{grammar}
- view as pdflatex will produce error
- export as .tex and then run command $ pdflatex file.tex will NOT have error
Kind regards

When compiled from within LyX, the .tex file and the graphic file are
copied to a temporary directory where (pdf)latex compilation occurs. In
this process the file names are altered. That's just the way LyX works.
It seems that syntax.sty interferes with that process, causing
compilation to fail (for reproducing your bug, it was sufficient to add
a graphic and the \usepackage{syntax} line). LyX cannot guarantee to
support every latex package available. I hope you can find a fix or an
alternative on your end.

Julien

The problem here is that syntax.sty makes '_' an active character.
A possible workaround is restoring its catcode after loading
syntax.sty, i.e., something like this:
\usepackage{syntax}
\AtBeginDocument{\catcode`\_=8}
