Problem using mptopdf with Metapost containing LaTeX

Problem using mptopdf with Metapost containing LaTeX

[Martin Buchmann]

Hi,

I am not really a ConTeXt user but use the mptopdf script to convert my 
mp drawings directly into pdf which was working great in the past. 
Yesterday and the day before i updated my TeX system using Gerben's 
i-Installer to the new gwTeX foundation and to the latest ConTeXt beta 
and since then I get an error if my Metapost file contains LaTeX control 
sequences:

Here is my minimal example:

prologues:=2;
verbatimtex
\documentclass[12pt,a4paper]{article}
\begin{document}
etex

beginfig(1);

   label(btex Test etex, (1,1) );

endfig;
end

I tried to understand which script is actual called when i call mptopdf 
but got kind of lost in the sequence of shell script calling ruby 
scripts calling perl scripts, etc. So, I wasn't able to find out the 
right command line options, etc. for making mpost aware of calling latex 
instead of tex. Can someone help me out here?

Best regards
   Martin

Same here. I am guessing this is a bug in the ruby version of texexec,
because it used to work with the perl version, for sure.

Not here:

[taco@glenlivet tmp]$ mptopdf --latex mpfile.mp

MPtoPDF 1.3.2 : running 'texexec --mptex '
TeXExec | processing graphic 'mpfile.mp'
TeXExec | using internal mptotex converter
TeXExec | processing document 'mpfile-temp.tex'
TeXExec | no ctx file found
TeXExec | tex processing method: context
...

ends in the same error (context complaining about \documentclass)

No, I get the same error message as before.

I also tried 'TEX=latex mptopdf thatfile.mp' but it didn't work,
though 'TEX=latex mpost thatfile.mp' worked.  Not sure if any of the
included post to c.t.t. is relevant, although I can no longer
reproduce this part -- not sure why:

  But setting the TEX env variable worked (without the %&
  line):

    TEX=latex mptopdf yourfile.mp

Did you try %&latex ?  Not sure if the MacOS filesystem is case
sensitive, but on regular Unix/Linux it matters.

Does 'mpost yourfile.mp' work?  Even when I put in %&latex (lowercase)
after the verbatimtex, it didn't work at first here (Ubuntu 6.10,
mostly TeXLive 2005 with 2006.12.27 context, mpost 0.993, i386).  This
subcommand failed:

   tex --parse-first-line --interaction=nonstopmode mpxerr.tex

Running it by hand shows where the failure is:

  This is TeXk, Version 3.141592 (Web2C 7.5.5)
   %&-line parsing enabled.
  ---! /var/lib/texmf/web2c/latex.fmt was written by pdftex
  (Fatal format file error; I'm stymied)

The problem is that latex is nowadays a symlink to pdftex (or pdfetex)
so when latex.fmt was generated, it was generated by pdfetex.  Whereas
'tex' is still regular (non-pdf) tex, so when it reads the '%&latex'
line, it loads latex.fmt and cannot understand it.

So I made tex a symlink to pdfetex, and 'mpost yourfile.mp' worked
then.

But 'mptopdf yourfile.mp' fails in the same place as for you.  Not
sure why.  But setting the TEX env variable worked (without the %&
line):

  TEX=latex mptopdf yourfile.mp

You might post your example to the context mailing list
(ntg-context@ntg.nl), where you will get more expert assistance.
