"Unable to make mpx file"

"Unable to make mpx file"

[Johannes Hüsing]

Greetings,

when including TeX expressions within Metapost within a ConTeXt source, 
I get the error cited in the subject line.

An examination of the mpxerr.log file reveals that the verbatimtex 
inclusions \global\loadfontfileoncetrue are not to TeX's liking.

Grepping context/base for \loadfontfileoncetrue yields no result. 
Where is Metapost's TeX engine supposed to get the definition from?

Sorry I have asked this question before (on Apr 14th), but not yet received 
an answer.

Greetings 

Johannes

so, adding \newif\ifloadfontfileonce to your cont-new.tex will solve th 
eproblem

Indeed, this solves the problem.

I have another problem with an "Emergency stop" message from MetaPost 
which doesn't show up when I include the MP code in beginfig/endfig and 
process it through Metapost: Could anyone give me a clue?

i think that this is now ok in the latest release (i had to take care of 
the active colon anyway)

hm, this should be no problem, unless some of those mpost mem problems is 
plyaing up, do you use the latest texutil?

otherwise, can you send me the minimal failing file?

(maybe this mpx env var is spoiling things)

Let me put it this way: When MetaPost is run from within texexec, no 
mpxerr.log is generated. When I run MetaPost myself on the test-mpgraph.mp
without the above inclusion, mpxerr.log is generated and reads:

This is TeX, Version 3.14159 (Web2C 7.3.3.1) (format=tex 2002.2.24)  8 JUL 2002 21:41

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

What I am doing now is using texexec --automp myfile after editing
myfile.tex by including a second example:

\setupoutput[pdftex]
\mainlanguage[de]
\useencoding[win]

\runMPgraphicstrue
%\protectbufferstrue

%  Hack, um " nicht als active character zu definieren,
%  während Metapost bearbeitet wird
\appendtoks \let\handlecompoundcharacter\string \to \everyMPgraphic

\setupbodyfont
  [sansserif, 18pt]

\startMPinclusions
verbatimtex
\newif\ifloadfontfileonce
etex
\stopMPinclusions

\starttext

\startuseMPgraphic{beispiel}
label(btex Hallo Welt etex, origin);
\stopuseMPgraphic

\useMPgraphic{beispiel}

\startuseMPgraphic{voorbeeld}
label(btex Hallo wereld etex, origin);
\stopuseMPgraphic

\useMPgraphic{voorbeeld}

\stoptext

This produces the "Unable to ..." messages, only twice now. Now I run
MetaPost on the myfile-mpgraph.mp file. It contains only the second 
example, but it compiles ok, and the resulting file myfile-mpgraph.2 
looks like proper Postscript to me.

Now I repeat texexec --automp on the tex file, which compiles without an 
error. This is the transcript:

Any help is appreciated.

This kind of things is hard to trace from a distance. The problem is that 
mp needs those conversion programs (although i'm thinking of replacing mp 
to tex i.e. handle it in texexec since it seems to fail occasionally).

Can you try

texexec --automp yourfile

this does a 'run in between job' instead of realtime.

"Unable to make mpx file"

[Johannes Hüsing]

Greetings,

again, I am experiencing problems with MetaPost creating files with text
included.

The following is the contents of test-mpgraph.log after processing a file
calles test.tex:

This is MetaPost, Version 0.641 (Web2C 7.3.3.1) (mem=metafun 2002.4.10)  10 APR 2002 22:25
**test-mpgraph
(test-mpgraph.mp
{randomseed:=525}
write0 = `test-mpgraph.mpo'.

>> test-mpgraph.mp
>> test-mpgraph.mpx
! Unable to make mpx file.
l.90 label(btex
                Hallo wereld etex
The two files given above are one of your source files
and an auxiliary file I need to read to find out what your
btex..etex blocks mean. If you don't know why I had trouble,
try running it manually through MPto -tex, TeX, and DVItoMP.

This is what the source looks like:

\setupoutput[pdftex]
\mainlanguage[de]
\useencoding[win]

\runMPgraphicstrue
%\protectbufferstrue

%  Hack, um " nicht als active character zu definieren,
%  während Metapost bearbeitet wird
\appendtoks \let\handlecompoundcharacter\string \to \everyMPgraphic

\setupbodyfont
  [sansserif, 18pt]

\startMPinclusions
verbatimtex
\newif\ifloadfontfileonce
etex
\stopMPinclusions

\starttext

\startuseMPgraphic{beispiel}
label(btex Hallo wereld etex, origin);
\stopuseMPgraphic

\useMPgraphic{beispiel}

\stoptext

What could be the reason? 

Greetings
