A while ago on this list, it was suggested (by David Bertoni) that,
because of the effort to maintain compile-time and binary stability
between successive versions of Xalan C++, it should theoretically be
possible to build the old XML::Xalan Perl wrapper -- originally designed
for Xalan C++ 1.3 -- against Xalan C++ 1.6.
Unfortunately, this turns out not to be the case. I was able to build
ICU 2.6, Xerces C++ 2.3.0, Xerces Perl 2.3.0-0, and Xalan C++ 1.6 all
successfully. Now, trying to build XML::Xalan against Xalan C++ 1.6, I'm
running into compilation issues that are definitely based on changes to
the Xalan C++ source tree. I've looked into the problem a little bit,
but the strange part is that the first error I get in a long chain of
errors is a parser error.
For this to make any sense, you'd have to see the source code for
XML::Xalan. If anyone has the time to take a look, here's the error I'm
currently getting (more comments follow error):
c++ -c -I/usr/local/src/xml-xalan-1.6/c/src
-I/usr/local/src/xerces-c-src_2_3_0/include/xercesc

gmake: *** [XSv.o] Error 1
Interestingly, if I comment out the namespace directive in
$XALANCROOT/src/xalanc/XPath, the set of errors changes dramatically.
I've tried unsuccessfully to contact Edwin Pratomo, the original
maintainer of XML::Xalan, several times over the past several months.
There's been talk of +1ing XML::Xalan as an official Apache XML Project.
I'd be happy to help with this effort (I'm already trying to help Jason
Stewart with at least the documentation of Xerces Perl).
I figured I'd (cross-)post here to see if anyone more familiar with
Xalan C++ 1.6 internals (or Xalan or C++ in general) might know what's
causing the parser error and other problems.
I've got a detailed build document for the entire Xerces/Xalan suite
(+ICU) for Linux that works for Xerces 2.0/Xalan 1.4 (including
XML::Xalan). I'd be happy to post the version of this that works for
Xerces 2.3/Xalan 1.6 (not including XML::Xalan, unless someone replies
to this post ... :).
Thanks!
