Problem using LaTeX in MetaPost

Hi,

I'm using MiKTeX version 2.9 and MetaPost version 1.504. I'm no longer able to use LaTeX in MetaPost. The file

verbatimtex
%&latex
\documentclass{article}
\begin{document}
etex

input latexMP;

filenametemplate "%j-%3c.mps";

beginfig(1);

draw (0, 0)--(150, 150);
label(btex $A$ etex, (0, 0));
show mpversion;

endfig;

verbatimtex
\end{document}
etex

end

fails because LaTeX commands aren't recognized. The error file is

This is TeX, Version 3.1415926 (MiKTeX 2.9) (preloaded format=tex 2012.2.7) 7 FEB 2012 10:28

Maybe version 1.504 of MP does not write the texfile correctly.
Try to look in the corresponding file (you will find its name in 
the log file), if %&latex would not be at the first line, then 
perhaps try to find older MikTeX version of MP (1.212 works fine, 
I hope).

You can always switch to TeXLive which works very well on Windows.

Which program actually evaluates the %&latex line?

This is obviously Knuth's TeX but the LaTeX format requires pdftex.  I
don't think the %&latex line can work here.  A better solution is to
make etex the default engine.  It's built upon pdftex too.

In TeX Live etex is the default engine indeed.  When I remove the
%&latex line, I get

This is pdfTeX, Version 3.1415926-2.3-1.40.12 (TeX Live 2011) (format=etex 2012.1.16)  7 FEB 2012 20:39
entering extended mode
 restricted \write18 enabled.
 %&-line parsing enabled.
**mpyty8eE.tex
(./mpyty8eE.tex
! Undefined control sequence.
l.1 \documentclass
                  {article}

So it's a bug in MiKTeX.

  Reinhard

Re: Problem using LaTeX in MetaPost

Hi,

If I understand correctly, this means that I won't be able to use LaTeX in MetaPost, right? At least not with MiKTeX 2.9.

Kind regards,

You can probably use it with the command line option --tex=latex.

This tells mpost which engine to use _before_ it reads its input file.

If this works, it might be worthwhile to file a bug report to the
MiKTeX maintaner(s).

Using this option, the file compiles OK, but YAP fails to display the picture after using TeX mproof. The error message is this:

It means that Ghostcript can't find the font cmmi10.  I suspect that
you have to set the prologues variable appropriately in your .mp file
so that dvips can find and insert the fonts from the texmf tree.
Ghostscript itself isn't aware of them.

BTW, TeX Live skipped version 9.00 due to a bug in color handling
which was fixed in version 9.04.  Maybe TeX Live is the better choice
indeed, as Yogeshwarsing proposed.

  Reinhard
