Re: texexec not launching mpost

["Denis B. Roegel" <Denis.Roegel@loria.fr>]

I have narrowed the problem down. It is certainly
connected with btex/etex. If I comment the first draw below,
it works. If it is not commented, the mpgraph is not found.
I'd welcome an explanation!

My texmf.cnf file has

shell_escape = t

and my ./cont-sys.tex file is

   \runMPgraphicstrue 
\runMPTEXgraphicstrue
  \recycleMPslotstrue 
\useMETAFUNformattrue

And the September 21 context is in /usr/local/tex5/texmflocal,
since it is newer than the texlive 5 CD.
