I installed ConTeXt in 2009 in my laptop and wrote some documents. Now I have installed ConTeXt in other computer and tried to process some of those documents but it doesn't work.

 

It looks that there is something wrong with Metapost/Metafun. I have tried a simple program like

 

\starttext

 

Testing

 

\startuseMPgraphic{gh}

draw thelabel.rt("the right way",a) withcolor .625red ;

\stopuseMPgraphic

 

\useMPgraphic{gh}

 

\stoptext

 

Then I get:

 

system          > begin file kk2.tex at line 1
metapost        > initializing instance 'metafun' using format 'metafun'
metapost        > loading 'metafun.mp' (experimental metapost version two)
! terminal: >> a
>> (3,0)
! Not implemented: (unknown numeric)+(pair).
<to be read again>
                   -
thelabel->...((EXPR4)+labeloffset*laboff(SUFFIX2)-
                                                  (labxf(SUFFIX2)*lrcorner.p...
<*>  draw thelabel.rt("the right way",a)
                                         withcolor .625red ; ;

.

system          > tex > error on line 10 in file kk2.tex: terminal: >> a
>> (3,0)
! Not implemented: (unknown numeric)+(pair).

                   -

<*>  draw thelabel.rt("the right way",a)
                                         withcolor .625red ; ;

 

 

Any ideas? Thank you.
