[metapost] Error when converting metapost files to PDF files

[Wentao Zheng]

Hi,

I'm using MikTeX system and recently I met a problem when converting
metapost files to PDF files with the program 'epstopdf.exe'

Problem description:

             mp.exe             epstopdf.exe
figure.mp  ---------> figure.1 ---------------> figure.pdf

When I used some codes such as 'label(...)' to produce some text,
mp.exeworks fine with no error, but
epstopdf.exe print error message like:

epstopdf.exe figure.1
Error: /undefined in cmr10
Operand stack:
   (hello)
Execution stack:
   %interp_exit   .runexec2   --nostringval--   --nostringval--
--nostringval--   2   %stopped_push   --nostringval--   --nostringval--
--nostringval--   false   1   %stopped_push   1   3   %oparray_pop   1   3
%oparray_pop   1   3   %oparray_pop   1   3   %oparray_pop   .runexec2
--nostringval--   --nostringval--   --nostringval--   2   %stopped_push
--nostringval--
Dictionary stack:
   --dict:1115/1686(ro)(G)--   --dict:0/20(G)--   --dict:70/200(L)--
Current allocation mode is local
Last OS error: No such file or directory
MiKTeX GPL Ghostscript 8.15: Unrecoverable error, exit code 1

How to solve this problem?
Thanks!
