<tt><font size=2>Dear Bryan,</font></tt>
<br>
<br><tt><font size=2>> I've compiled each of the TeX files containing
error examples using <br>
> a fresh Ubuntu 10.10 install, the 2009-10 version of TeXLive, and
<br>
> Xy-pic 2.8.5 (I replaced 2.7 manually). On this system, everything
<br>
> produces the correct output except the fourth example. Lots
of <br>
> warnings are generated for all but the second example, however.
I <br>
> suspect that it is the handling of these warning situations that's
<br>
> causing the problem on some systems.</font></tt>
<br>
<br><tt><font size=2>The error report in the log file for all of the examples
contain an explicit error like this one:</font></tt>
<br>
<br><tt><font size=2> ! Xy-pic error: No `pdf@@@' option.</font></tt>
<br><tt><font size=2> \xyerror@ ...#2}\fi \errmessage {Xy-pic error:
#1}</font></tt>
<br><tt><font size=2>
}</font></tt>
<br><tt><font size=2> l.86 \makeatother\xyoption{pdf}</font></tt>
<br><tt><font size=2>
\fi\fi</font></tt>
<br><tt><font size=2> Your \xyoption {pdf} request could not be granted:
the required</font></tt>
<br><tt><font size=2> file `xypdf.tex' could not be located. Please
make sure that it is</font></tt>
<br><tt><font size=2> properly installed before continuing.</font></tt>
<br>
<br><tt><font size=2>This seems to suggest that your manual install of
Xy-pic 3.8.5 did not quite succeed, in particular the proper PDF option
is never actually loaded.</font></tt>
<br>
<br><tt><font size=2>When I try to run the example I simply get overflow
errors resulting from the zero-sized round object, as Ross has explained
elsewhere.</font></tt>
<br>
<br><tt><font size=2>Regards,</font></tt>
<br><tt><font size=2> Kris</font></tt>
