Hi Jean Magnan,

You should add \useMPlibrary[txt] in order to get textext working. Further define AX as a path only. In the dummy-graphic say drawdblarrow AX.withcolor blue;

After these changes I got the label as well as the double arrow. Hi,

Hi,

Actually I tried your file and got the same "Undefined" message in place of the graphics. However the following works for me (latest ConTeXt installed with i- Installer on Mac OS X 10.4.6):

\setuppapersize[S6][S6] \setupcolors[state=start]

\starttext \startbuffer[essai] numeric u; u = .4cm; path p; p = (10u,0)--(0,0)--(0,10u); pickup pencircle scaled .8mm; drawdblarrow p withcolor red; label.rt(textext("$3x^2+\pi$"), (5u,6u)); \stopbuffer

\placefigure[left]{bla.bla}{\processMPbuffer[essai]} \input dawkins \stoptext

If I add \useMPlibrary[txt] at the beginning everything works fine as well. But if I add \runMPgraphicstrue then I get the "Undefined" message in the PDF. So it seems that the problem comes from this latter command. Hi all, I tried various ways as suggested on my file with the setups \useMPlibrary[txt] and \runMPgraphicstrue. The only combination that's working is to have \useMPlibrary[txt] and not the other. Is it proper to my installation, as others seem to have other requirements?

As for "texmfstart texexec" it is unknown on my machine, I don't have ruby installed anyway (is it necessary?). Thanks to all! -- jean

This file compiles fine here (Windows XP + ConTeXt ver: 2006.05.17 10:08). I get proper text in the right location.

Your first message said that you were running texexec.pl. Try switching to texexec.rb, i.e., invoke context with

texmfstart texexec <filename>

the file compiles ok here textext is scanned for (but you can force it with \forceMPTEXgraphictrue) This is what supp-mps defined: \forceMPTEXcheck{etex} \forceMPTEXcheck{textext} \forceMPTEXcheck{graphictext} Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Humble I got this one wrong! Willi Aditya Mahajan wrote:

Hi Jean Magnan,

Why is this so? I could not find anything in meta-txt.tex to suggest that it is needed for textext. The example works even without \useMPlibrary[txt].
