Mpost disabled?

Mpost disabled?

Hi!

I always have my problem with mpost (MiKTeX 2.1, ConTeXt 2.5). When I try to compile a ppchtex file I get :

-Randomizer initialized to 1493581758.
-system(mpost -progname=mpost -mem=metafun glucose-mpgraph)...disabled.
-
-
-figures        : figure glucose-mpgraph can not be found

Mpost seems to be disabled, where can I enable it?

It's not Metapost, that is disabled, but 'system', that is, calling
external programs.
You can change this in texmf.cnf (at least on tetex):

shell_escape = t % enable system commands via \write18{...}

BTW: What means 18 in \write18? 

I don't really know, if this fixes the problem (is 'system' a Perl
command? then there must be a restriction to Perl)

I haven't tetex and texmf.cnf...

I have tried a lot of things since the last time. I have finally found that
when I uncomment the line "\runutilityfiletrue " in cont-sys.tex, it seems
to work!

What is exactly this line?

Do you have MiKTeX? MiKTeX 2.x supports the \write18 trick, but
you must enable it either in the miktex.ini configuration file or
through the --shell-escape or -enable-write18 command line switch.

tex has 0-15 file handles, so 18 is safely outside this range; the 18 comes 
from some unix pipe or whatever number i'm told.
