error with metafun

[Peter Münster]

Hello,

with the latest ConTeXt on TeX-live 2007 and this input file:

\starttext
\startuseMPgraphic{test}
draw fullcircle scaled 4cm withpen pencircle scaled 1cm ;
setbounds currentpicture to boundingbox fullcircle scaled 4cm ;
\stopuseMPgraphic
\useMPgraphic{test}
\stoptext

I get the following error in dvi-mode:

This is MetaPost, Version 0.993 (Web2C 7.5.6)

Could anybody help please?

No error here, but my context and metapost are newer and my
pdftex  is older than TL, so that may not mean much.

Best, Taco

Did you use the "--dvi" switch of texexec?

works ok here (there has been a problem in mp with empty lines but that was solved; maybe do a purge

I didn't, but I did just now, and yes, it is broken.
I get the same error you had, with the latest beta.

Looks like that bit of the ConTeXt code doesn't like the new
procsets in the new metapost version, because with this change:

   \starttext
   \startuseMPgraphic{test}
   mpprocset:=0;
   draw fullcircle scaled 4cm withpen pencircle scaled 1cm ;
   setbounds currentpicture to boundingbox fullcircle scaled 4cm ;
   \stopuseMPgraphic
   \useMPgraphic{test}
   \stoptext

It runs fine.

Best, Taco
