This is strange. This is pretty legal web2c. Is there a non web2c mp living
on your system?

Real strange since it works here (windows I must admit). 

You files looks ok. What does texexec --verbose report? 

Looks like i have to test linux -)

I use miktex + pdfetex binaries from fptex on WinNT

>>immidiate write 18 is enabled and

i changed the entry in texmf.cnf so it only is valid for pdfetex.
does metapost need this entry? How it is to set for miktex?

Hi Hans Hi all,

i have the same problem.

newest beta context + texexec
newest pdfetex (fp) 12.09.2000

only the last mpgraphic is written into the mpgraph.mp
and no graphic can be found.

mpost complains on the commandline about:

mpost: unrecognized option ´-progname=mpost´

immidiate write 18 is enabled and
i have following entries in my cont-sys.tex:

Look in texmf.cnf. There is a line about shell_escape. Set it to true
(t).

If you work under UNIX and cannot set this because your admin is against
it, you may overrule it using a shell (environment) variable: export
shell_escape=t / setenv shell_escape t.
If you work under Windows* you should be able to set it yourself (don't
know about NT), but I think it should work there as well.

Metaerror?

Hello All,

Running this file produces (on my system) a page with the same fore and
background graphic, i.e. the overlay graphic disappears and is replaced
by the other mpgraphic. I run the latest stuff, with all the options in
cont-sys.tex

I tried to remove the recycle slots option, but that didn't work either.

\setupcolors

  currentpicture := currentpicture ysized (\overlayheight-.5cm) ; 
\stopuniqueMPgraphic

Are you sure then that you enabled immediate write 18? Since your file runs
okay here. 

   \runMPgraphicstrue
\runMPTEXgraphicstrue
  \recycleMPslotstrue
  \protectbufferstrue % not really needed here btw
\useMETAFUNformattrue

combines with enables wriote 18 in texmf.cnf should do the magic trick.

Btw, you can say there btex TEXT etex to get btex/etex labels.

It runs, but complains. Perhaps output is not flushed??

I'll try the latest pdftex (I did run version f)

Except \protectbufferstrue (adding this didn't help).

Yes, I figured out that I needed to specify that there.

When executing this command:

texexec --mpformat=metafun --mptex --nomp --once mpgraph

The run ends with:

              run time : 2 seconds
              metapost : mpgraph
                format : metafun
This is MetaPost, Version 0.641 (Web2C 7.3.2x)

It may indeed be an error, since there is an 'end' in the file. Mayeb mp
waits for something else.

It's really, really strange.

With:

	texexec --mptex mpgraph

mpost fails, with 

	mpost \&metafun mpgraph	

it runs fine.

Can some kind soul send me his linux i386 mpost binary??

I'll see if I can perhaps recompile mpost.

Hi Berend,

Have you checked the contents of the temporary
log and error file mpost generates?

Maybe this will bring you closer to a discovery
of the error.

Also I noticed you use btex etex which doesn't
work properly with me. In stead I am using the
code appended below which I shamelessly stole
and adapted from
http://www.mathp7.jussieu.fr/~zoonek/LaTeX/Metapost/metapost.html 

You can use this macro and play sexy games like:
 .....
 counter := 3;
 boxit.ctr( LATEX( "The value of counter is "
                 & decimal( counter )
                 & ". Cool no?"
                 )
           );

Perhaps context's btex and etex work fine---I
don't use context. If you decide to use the macro
you may wish to change its prelude a bit so that
it complies with your Context settings.

Just a thought.

Marc van Dongen

btex .. etex returns a picture picked up from a file generated by a bunch
of mp tools.

This is not needed in context since it saves environments and additional
data already. Also, this macro is rather hard coded -) 

see metafun manual: 

\startMPenvironment 
  \setupbodyfont[pos,12pt]
\stopMPenvironment 

So, for string composition purposes, one may define: 

vardef TEX primary s = 
  write "btex " &s " etex" & EOF to "mptextmp.mp" ;
  scantokens "input mptextmp"  
enddef ;  

But there are easier ways I think. 

Btw, i'm thinking of a different mechanism which permits making macros with
embedded btex/etex things,

It is (version 2.2)

It seems that texexec --mptex mpgraph doesn't really read mpgraph.mp. I
can make typo's in mpgraph.mp but there are no warnings.

The command is executed though.

Conduct a find in the directories where (La)TeX searches.
I bet you there will be several mpgraphs.mp.
 find thedirectorywherelatexsearches -name mpgraph.mp
In my system it's in
 teTeX/share/texmf/doc/metapost/base/mpgraph.mp

Next rename the on that starts with the four lines:
input graph

%if false:  %% Begin skipping already debugged figures
%fi input sarith %% End skipping of already debugged figures

This is John Hobby's mpgraph.mp.

I thin that should do the trick.

Are you sure that . is prepended to your mp path?

Really necessary??

But perhaps I'm a bit further now: I've hacked texexec to copy
mpgraph.mp to tmp.mp and tmp.mp is 0 bytes at that time (that explains
the error). mpgraph.mp is ok when texexec finishes...

Perhaps some close or flush doesn't work???

My perl version is: 5.005_03

It seems that the command that is executed:

	pdfetex  -progname=context  \&cont-en tmpgraph

removes mpgraph.mp. And because a copy is kept in a .kep file, this one
is copied back so everything looks fine afterwards when executed by
texexec.

That is because there were problems with buffer sizes (fixed now by fabrice
popineau). I let texexec copy the file, and add line breaks but not spoil
the original.

What I don't understand is that it does not work on your machine while it
works ok on mine.
