I do not know if it is proper to post this question to this list but a miktex-user suggested to send it to you because there were not suggestioned solutions on that list. My apologies if I am sending this to the wrong list. This is the problem I am new to MiKTeX and I am have not been able to solve a problem that arises when I try to use the m-metapo package. Here is a simple example \documentclass{article} \usepackage{m-metapo} \begin{document} Why this error? \end{document} This is the error I get (C:\MiKTeX\Main\tex\context\base\supp-mis.tex loading : Context Support Macros / Miscellaneous (2004.10.26) ) loading : Context Support Macros / MetaPost Inclusion ! Undefined control sequence. \startMPinclusions ->\dosingleempty \dostartMPinclusions l.245 \startMPinclusions \stopMPinclusions ? The relevant part of the log says \MPextensions=\toks18 ! Undefined control sequence. \startMPinclusions ->\dosingleempty \dostartMPinclusions l.245 \startMPinclusions \stopMPinclusions ? r OK, entering \nonstopmode... ! Use of \dostartMPinclusions doesn't match its definition. l.245 \startMPinclusions \stopMPinclusions If you say, e.g., `\def\a1{...}', then you must always put `1' after `\a', since control sequence names are made up of letters only. The macro here has not been followed by the required stuff, so I'm ignoring it. I have wasted hours on this stupid thing. I would greatly a hint to solve this. I have a large number of metapost graphs that I used through the m-metapo package Thank you for any help Luis A. Escobar Louisiana State University
