Hi Hans Hi all,

i have the same problem.

newest beta context + texexec
newest pdfetex (fp) 12.09.2000

only the last mpgraphic is written into the mpgraph.mp
and no graphic can be found.

mpost complains on the commandline about:

mpost: unrecognized option ´-progname=mpost´

immidiate write 18 is enabled and
i have following entries in my cont-sys.tex:

\runMPgraphicstrue
\runMPTEXgraphicstrue
\recycleMPslotstrue
%\protectbufferstrue
\useMETAFUNformattrue

btw. \protectbufferstrue never worked here
always context/texexec complains about graphic not found.

my file:

\startuseMPgraphic{Fig 1}
linejoin:=mitered;
for i = 0 upto 4:
z[i]=(7cm*sind(i*360/5),7cm*cosd(i*360/5));
endfor;
draw z0--z1--z2--z3--z4--cycle;
draw z0..z1..z2..z3..z4..cycle;
pickup pencircle scaled 1.5pt;
draw z2--z3--(x3,y0)--(x2,y0)--cycle;
\stopuseMPgraphic
\startuseMPgraphic{Fig 2}
linejoin:=mitered;
z1=(0,0); z2=(140mm,0); z3=(140mm,140mm*.75); z4=(0,140mm*.75);

{\sc Zwei} Konstanten regieren die Proportionen eines gut gemachten Buches:
Hand und Auge.
Das gesunde Auge ist immer um zwei Spannen von der Buchseite entfernt, und
alle Menschen fassen Bücher
auf die gleiche Weise an.
