Strange error with package loading and class file
Jon
convenience of my students. If I put the \RequirePackage statements in
the class file then I get
*hyperref using driver hpdftex*
(/usr/local/gwTeX/texmf.local/tex/latex/hyperref/hpdftex.def))
! Missing = inserted for \ifnum.
<to be read again>
v
l.3 \ifxetex
?
! Missing number, treated as zero.
<to be read again>
v
l.3 \ifxetex
?
\ifxetex just happens to be the first line after the \documentclass
declaration if I change the text on that line I get the same error with
the new text instead of \ifxetex. Now if I copy the \RequirePackage
statements from the class and paste them into the preamble changing
them to \usepackage declaration I do not get this error. I am stumped.
I did a list files and they are calling exactly the same files in
exactly the same order. What could be the culprit? Here are the file
lists

The text of test.tex and paper.tex is exactly the same but paper.tex
uses the class I am trying to create.

Thus neither hyperref nor ifxetex has something to do with it.
The error is probably somewhere near the end of the class file
(look for \ifnum).

It's a bit of a stab in the very very photon-free regions, but this
might be the "v" in the version identification of either your class or
one of the packages you load. The format documented by clsguide,
\ProvidesFoo{name}[YYYY/MM/DD other information], is mandatory. If you
say \ProvidesFoo{name}[v0.21] and the user requires a certain version,
your v0.21 will at some point be compared numerically against the year
given by the user, which will probably result in errors like yours.
Without seeing a minimalized version of your class, that's the best I
can think of.

Weird. I don't get it.
When I can't work out where exactly an error is occuring, I use
\typeout{HERE I AM}
in the source to trace where the error is.
Sorry I can't be of more help,
Will
steph...@cox.net
very picky indeed.
If you change:
\ProvidesClass{woosterpaper}[2007/1/1 v1.0 Wooster paper class]
to
\ProvidesClass{woosterpaper}[2007/01/01 v1.0 Wooster paper class]
the problem goes away. As Ulrich pointed out, the line must be in the
format:
\ProvidesFoo{name}[YYYY/MM/DD other information]

Thank you very much. I had never heard of this behavior before. 15
years and still learning :-)
