[Gretl-users] LaTeX on OSX

Hi, When I ask Gretl to view the output as LaTeX file, I get the following message : %%%%%%%%%%%%%%%%%%%%%%% This is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009) (format=pdflatex 2010.4.7) 9 APR 2010 13:46 entering extended mode %&-line parsing enabled. **\batchmode \input window (./window.tex ! LaTeX Error: Missing \begin{document}. %%%%%%%%%%%%%%%%%%%%%%% I think Gretl doesn't find the file with LaTeX header (gretlpre.tex). I have red the doc but I don't understand where this file lives on Mac OS X. Could you help me? Frédéric
