Hi there,
I updated my org-mode repository last night and found today that my
LaTeX export wasn't working anymore because it couldn't find the LaTeX
class: "No definition for class `%s' in `org-export-latex-classes'".
The class name I'm using includes "/" characters. However, the regex
for matching #+LaTeX_CLASS allows only alphabetic characters or
"-". The following change fixed this for me, but perhaps it's now a
little too inclusive?
diff --git a/lisp/org-latex.el b/lisp/org-latex.el
index 649e4a7..e9502ae 100644
--- a/lisp/org-latex.el
+++ b/lisp/org-latex.el
@@ -1346,7 +1346,7 @@ LEVEL indicates the default depth for export."
(save-restriction
(widen)
(goto-char (point-min))
- (and (re-search-forward "^#\\+LaTeX_CLASS:[ \t]*\\([-a-zA-Z]+\\)" nil t)
+ (and (re-search-forward "^#\\+LaTeX_CLASS:[ \t]*\\(.+\\)$" nil t)
(match-string 1))))
(plist-get org-export-latex-options-plist :latex-class)

Best,
Richard

Yes, this is a bit too inclusive, as the (match-string 1) would also
contain spaces, for example. I've pushed a commit allowing "/" chars
for LaTeX classes -- please test it and let me know.
Thanks,

It seems to me that that's a bad idea: class names correspond to file
names (without the .cls extension), so "/" characters will probably
cause confusion (at least on Unix-based filesystems).
So instead of extending org to recognize these names, I would recommend
not using slashes in class names in the first place
- or backslashes, or even punctuation characters:
restricting oneself to alphanumerics seems like the safest bet.

But what's the relationship between org-export-latex-classes and LaTeX
class files?
Best,

C-h v org-export-latex-classes RET
It's an alist where the LaTeX class name is used as a key:
alist-key == latex class name -> latex class file.
