Paragraph ended before \handleMPsequence was complete.

[Jim]

I'm getting the error message in the subject line and I'm having
trouble getting rid of it.

I have a book that I've compiled in the past with latex/dvips and it
works fine. I'd like to simplify the workload with pdflatex. These
lines:
many members of the domain.
\begin{center}
\includegraphics{ch3.5} % bean to bean; many to one
\end{center}
Recall that for any function $\map{h}{V}{W}$,
trigger the error
(./ch3.5
Runaway argument?
! Paragraph ended before \handleMPsequence was complete.

\par
l.18

I agree that the line 18 of ch3.5 (the output of a MetaPost run) is
indeed blank. However, I didn't put the blank there; MetaPost did.
Further, dvips seems to have no trouble with it.

I have the latest TeX Live, 2007. Does anyone recognize this issue?
Is this something I'm doing wrong, or a bug of some kind? I'd be very
glad of a tip.

Thank,
Jim

The error message is most likely from supp-pdf.tex which is used by
pdflatex to convert metapost eps into pdf. The error is either a bug in
metapost or supp-pdf. Can you post the metapost file used to create ch3.5?

Also: what version of metapost and supp-pdf.tex? And for good
measure, what version or the file pdftex.def and even of pdftex
itself. It might also be helpful to see the file ch3.5 itself.

And finally, a minimal .tex file, and any information about how
it and the .mp file are processed. Metapost doesn't usually put
blank lines in its output file, but some post-processors might.

Dan, Aditya,

Thanks for your help.

I have Ubuntu with TeX Live 2007. Maybe I should upgrade to the 2008
at some point, but frankly I'm busy doing CTAN all wrong. ;-)

Thanks,
Jim

My MetaPost is
$ mpost --version
MetaPost 0.993 (Web2C 7.5.6)
kpathsea version 3.5.6
Here is a reasonably minimal file and below it is the output that has
a blank line.
................ ch3.mp ......................
% CH3.mp
% MetaPost input file with chapter three pictures.

% Generic set: returns the path
def generic_set(expr a, b)=
(0a,.5b)..(0a,1b)..(1a,1b)..tension 1.2..(1a,0b)..(0a,0b)..cycle
enddef;

beginfig(5) % bean with mapsto
numeric u; %scaling factor
numeric v; %vertical scaling factor
numeric w; %horizontal scaling factor
u:=.18in; v:=u; w:=v;

save codshift; pair codshift; codshift = (7w,0);
draw generic_set(2w,4.25v);
draw generic_set(2.1w,4.4v) shifted codshift;
endfig;

end
.............................................................

Here is the result of running mpost; no post-processing.

I understand you to be saying that I am reading the error message
correctly, that the metapost output should not have a blank line, but
in any event here is a .tex file

As a second data point, there is also no empty line in the very
latest beta:
MetaPost, version 1.091 (kpathsea version 3.5.7)

Thanks for both data points. I have gotten the latest TL version and
it compiles correctly.
