Great job, Charlie! I installed 0.9.2 and everything works

Thanks for the update Kevin.  I'll close this ticket then. If you run into other issues, go ahead and create new tickets.

The big difference in behavior is error handling - you'll have to rewrite any error handler hooks.  Also, any raised exceptions have a lot more information, and are raised in a few more places.  So basically the bindings tell you a lot more now about problems when they occur.

Looks good so far.  I was able to build the gem at the very least.  I still need to test that no behavior was broken.

Nikolay and Kevin - Try the 0.9.1 release and see if that works for you.

Thanks for the quick bug report.

Yeah.  It's looking for more than just that one constant.

Actually, that won't work will it.  Hmm, looks like there will have to be a libxml version check.

Kevin, Nikolay,

Looks like Ubuntu has an older version of libxml.

That constant was added here:

http://mail.gnome.org/archives/svn-commits-list/2008-March/msg05252.html

Can either of you check a fix for me?

Update ruby_xml_error.c, line 208, like this:

#ifdef XML_FROM_SCHEMATRONV /* Only present in newer versions of libxml */
  rb_define_const(eXMLError, "SCHEMATRONV", INT2NUM(XML_FROM_SCHEMATRONV));
#endif

Then you should just be able to run make as root.  I only have Fedora boxes lying around at the moment.....

I can confirm.  I was just about to raise the issue myself.  Major deal breaker for us.

I'm trying to find a way to resolve it with the package manager, but nothing obvious is jumping out.
