Hello, I've updated miktex 2.8 to 2.9.

This file :

%prologues := 3 ;

verbatimtex
%&latex
\documentclass{article}
\usepackage{tarassmetapost}
%\usepackage[T1]{fontenc}
\begin{document}
etex;

input Macros-nk ;

u := 1cm ;

beginfig(1)
z0=(0,0); z1=(2u,7u); z2=1/2[z0,z1];z3=(7u,7u);z4=(5u,0); z5=1/2[z3,z4];
draw
(0,0)--(5u,0)--(7u,2u)--(7u,7u)--(5u,5u)--(5u,0)--(0,0)--(0,5u)--(2u,7u)--(7u,7u)--(5u,5u)--(0,5u);
draw (0,0)--(2u,2u)--(2u,7u) withpen pencircle dashed evenly;
draw (7u,2u)--(2u,2u) withpen pencircle dashed evenly;
%draw (3.5u,u)--(7u,7u) withpen pencircle dashed evenly;
%draw (2u,2u)--(5u,0) withpen pencircle dashed evenly;
%draw (5u,0)--(7u,7u);

label.bot(btex A etex, (0,0));
label.bot(btex B etex, (5u,0));
label.rt(btex C etex, (7u,2u));
label.lft(btex D etex, (2u,2u));
label.lft(btex E etex, (0,5u));
label.top(btex H etex, (2u,7u));
label.top(btex G etex, (7u,7u));
label.rt(btex F etex, (5u,5u));
label.lft(btex $O_1$ etex, z2 );
label(btex $\times$ etex, z2);
label.rt(btex $O_2$ etex, z5 );
label(btex $\times$ etex, z5);

endfig;
end

give me .log :

This is MetaPost, version 1.211 (MiKTeX 2.9) (MiKTeX 2.9) (mem=mpost

l.27 label.bot(btex
A etex, (0,0));
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 MPtoTeX, TeX, and DVItoMP

The command line est mpost -tex=latex. What must i do ?

Thanks, Jean-�ric.

Changing

verbatimtex
%&latex

to

verbatimtex%&latex

should solve the problem. As far as I remember, this is a
=93feature=94 (or a =93bug=94, depending how you see it) introduced with mp=
ost
1.210, by which *anything* after verbatimtex and up to etex, including
any whitespace and newlines, are left intact. This causes some
trouble, because %&latex ends up in the second line of the generated
file (given that the newline after verbatimtex is not stripped out)
and the tex processor does not parse it. So, that directive ends up
being ignored.

You may take a look at the release notes for mpost >1.210 to check
whether such behaviour has been corrected (I do not remember now).

Sorry, I have read your post too quickly. Actually, I am able to
compile your code if I comment the \usepackage{tarassmetapost} line (I
do not have that package). Are you sure that package is found? A look
into mpxerr.log should tell you what is wrong.

\usepackage{amsmath,amssymb,times,mathrsfs}

\newcommand{\Calig}[1]{\ensuremath{\mathscr{#1}}}
\newcommand{\C}{\Calig{C}}

but i've got the same matter.
I'll see later the problem, ans try to solve it.

METApost and PDFLatex Problem
Can anyone help with this problem getting started with Metapost and pdflatex? I can produce a diagram with Metapost and then convert it to pdf using ps2pdf. I can then incorporate the diagram into a Latex document using \includegraphics . The problem is that the diagram is A4 size, even if it is a small diagram, so I get a lot of empty space in my final document. I can reduce the size of the diagram by saying (for example) \includegraphics [height=60mm]{diagram.pdf} However, the shape of the space used is still 'A4 shape' (eg I can't have a square), and to avoid having empty...

Problem with MetaPost in TexLive
Hi, I'm trying to make illustration with MetaPost. But the greek symbols are missed in the eps file. And ";" symbol appears instead of "," symbol. I am using TexLive. However, MetaPost from the MikTex translates the same file to eps correctly. For example, this is my MetaPost file: verbatimtex \documentclass{minimal} \begin{document} etex; prologues:=1; beginfig(1); draw (0,0)--(140mm,100mm); label(btex $$H_{\phi_{m,n}}$$ etex, (50mm,30mm)); endfig; end.

Metapost : problem with xpart and paths.
Hi, I have a problem when creating paths which involve pairs created from xparts (or yparts) of other pairs in Metapost. Here is a minimal code causing the error to come. Remember that "x0" is the equivalent for "xpart z0". You can replace it and you'll get the same error. The strange thing is that you can print the pair p, but you cannot make paths with. The result of the compilation with mpost follows the code. Any jedis or padawans out there? Thanks for your help!!! pair p; z0 = (3,5); p = (x0,0); show z0; show p; beginfig(1); draw z0--p; endfig; end; For this c...

MikTeX, Metapost, epstopdf font problems....
I recently started learning to use Metapost to produce graphics. It works well, except I'm getting stuck trying to convert the graphics to PDF format so that I can use them in documents that I process with pdflatex. The process that I've been attempting is to take the "figure.1" (for example) document that mpost (from MikTeX 2.3) produces, and run it through epstopdf (also from MikTeX 2.3), and view the resulting "figure.pdf" file in Acrobat. Now, the "figure.1" is fairly easily readable, being Postscript; it includes the callouts for "cmr10" ...

[MetaPost] Problem labeling the y axes of an graph
Hi all, i'm using graph.mp to plot some data. The y range of this data is about [-42000:-34000]. By default the labels at the y tics are typeset using the A*10^B notation which i don't want here. So i changed the labels according to the documentation on page 10: for u=auto.y: itick.lft(format("%g", u Sdiv "1e3"), u); show u; endfor autogrid(itick.bot,); That's working fine besides the fact that it gives fives labels from -42 to -34 and i would prefer labels from -43 to -33. I used the setrange command to extend the axis but this left the tics unchanged. ...

Metapost terminal color, filling and paging problems

My terminal command is: set terminal mp color latex mag 0.7 solid Nevertheless the output is entirely black-and-white. The same output in postscript is cheerfully colorful (with postscript options). 2. My style is set style fill solid border 0 which to my best knowledge should result with colored bars in boxes plot. I get empty boxes. With postscript output the boxes are ni...

Problem: Metapost + graph.mp + big/small numbers
Hi! I have been using Metapost with the graph package for a while, mostly with good results. However, I have some problems generating graphs based on data with big and/or small numbers, even though the package should support this. For instance, input graph; beginfig(1); draw begingraph(6cm,3cm); gdraw "sample.d"; endgraph; endfig; end; with data file sample.d: 1.8e+11 8.5e-7 2.7e+11 8.3e-7 3.6e+11 8.7e-7 4.5e+11 7.6e-7 5.4e+11 7.1e-7 6.3e+11 7.7e-7 6.5e+11 6.1e-7 will generate a plot with a corrupt y-scale, but the x-scale ok....

I read the documentation carefully and found that the format.mp package is doing the typesetting job.

Problem with a problem
Hello, take a grammar G with alphabet {0,1} such that (the word problem for) the language L_G={w in (0+1)*|w\in L(G)} is very complex, say in PSPACE or some higher complexity class. Now consider an "easy" problem EASY like: "Is an element of L_G in L_G?". Well, this seems to be fairly easy because the answer is "yes" in any case. Hence the problem should be of small complexity. But if one models such a decision problem one has to construct a language L with alphabet A such that the word problem for L reflects exactly the decision problem which one is interested...

Is this a BIOS problem, a kernel problem or a user problem :-)
