MetaPost error

MetaPost error

[^Nitram^]

 Hello

 I'm very newbie in ConTeXt and I can't generate any document with
 MetaPost... For example: \startFLOWchart etc.

 I generate: makemem metafun
 I did texexec --make --alone metafun

 and I still have error:

 initexmf: don't know to dump metafun
 I can't find default mem file!

 Where I can set it or something else do to fix this ?...

 Best regards
 martin

OK, this is the way to go.

this is odd. What is this initexmf? 

After texexec --make --alone metafun the metafun.mem file needs to be placed in teh appropriate directory (web2c on web2c systems. Don't know about Miktex)

Some more information would be useful: 

do ConTeXt files (without metapost stuff) work correctly?
what system are you using?
what is the version of your ConTeXt system?

And please post the exact steps you did and the exact error messages.

Hi Martin,

The metafun.mem file is svaed in the directory where you run texexec --make
metafun. Thus you need to copy this file into a place where TeX can find it.
e.g. \...\texmf-var\web2c. Run mktexlsr

In order to be able to typeset FLOWcharts do not forget to load the
chart-module

At the beginning of your file just say: \usemodule[chart]

 Yes - thank You for Your time - now everything looks good.
 I fixed it by following:
 -install miktex (large version but I will experimental with
  small version) 
 -unzip new version of ConTeXt
 -remove cont-en.efmt file if exists
 -generate format en
 -generate specific language format
 -update and refresh MikTeX database
 -generate metafun format
 -copy mem file from fmt folder (where is stored after generate) to
  /mem/ folder(s)
 -update and refresh MikTeX database

 And everything looks good ;)

 I had some problems with generate metafun format - there
 I couldn't find mem file on hard disk. Maybe first time I
 forgot  '-update and refresh MikTeX database' ;)

 This the point for new users: after each operation do it ! ;)

 I used:
 This is pdfeTeX, Version 3.141592-1.11a-2.1 (MiKTeX 2.3)
 (preloaded format=cont-en 2003.9.4)  4 SEP 2003 23:12
 and:
 ConTeXt  ver: 2003.8.21  fmt: 2003.9.4  int: english  mes: english

 Best regards
 Martin

hm, strange, it seems that
externalfigure is redefined
This is ok

\starttext
\startMPcode
def externalfigure primary filename =
    if false :
        rawtextext("\externalfigure[" & filename & "]")
    else :
        image (
            addto currentpicture doublepath unitsquare
                withprescript "fg_name=" & filename ;
        )
%             unitsquare
%                 withpen pencircle scaled 0
%                 withprescript "fg_name=" & filename
    fi
enddef ;
draw externalfigure "hacker.jpg" xscaled 30mm yscaled 20mm ;
\stopMPcode
\stoptext
