Mailing List Archive: pyexpat.c help

Hello,

I'm trying to get ParsedXML to work in Zope 2.4.1 with Python 2.1. At
the ParsedXML site at zope.org, there is a zipe file with the VC++
project file to build pyexpat.pyd. I get this error when building:

Creating library Debug/pyexpat.lib and object Debug/pyexpat.exp

Error executing link.exe.

pyexpat.pyd - 13 error(s), 0 warning(s)

Is this .c written for python1.5 only? I put py2.1 files in the
include/lib path. Do I need a ver made to compile with 2.1? Also, what
is pyexpat.pyd's role in zope (what does it do/used for)? ANY help
would be very much appreciated; I've been trying for hours to make it
work...

Thanks in advance,
Brian W.

Hey,

I've sent a cc of this reply to the ParsedXML-dev and Fred Drake. Fred
hopes to start looking at the parser issues next week.

It's used by ParsedXML itself to do its parsing (translating the raw
XML data into a DOM tree). I'm not entirely sure
why we can't use Python 2.1's expat, but it seems it may miss some
features that ParsedXML needs (and some Python builds apparently don't
come with it at all).

Weird; it does compile for Python 2.1 on Linux so I'm at a loss why it
wouldn't compile under Windows. However, even on Linux the compiled
pyexpat seems to trigger segfault errors in the parser test suite, so
something is still wrong (but some limited testing showed the expat
that comes with Python 2.1 *also* suffers these problems..)

I have no experience with compilation on Windows however. I do have an
interest in seeing a Windows binary version of ParsedXML for Zope 2.4,
so I hope we can figure it out..
