Hmmm... What a pain.

First the bad news:
I'd love to do this, but I haven't even released 1.5.7 yet. I only have
pieces of 1.5.7 committed to CVS.
What needs to happen for 1.5.8 is that I need to create a *proper*
exception handling mechanism in XML::Xerces. Currently all parse
exceptions are caught by the standard ErrorHandler mechanism:
$handler = MyErrorHandler->new();
$parser->setErrorHandler($handler);
$parser->parse(); # an error here calls MyErrorHandler::error()
Problem is Parser::parse() can also throw XMLExceptions which are not
handled by this mechanism. Since most people don't care about those, I
hacked together a silly mechanism to catch them and exit printing out
the error. After reading the mod_perl FAQ I learned how I *should*
really be doing things, and it is much better, and it is the accepted
Perl way to do things.
This will require quite a bit of changes, none major, but many files
will be affected.
Now the good news:
I shouldn't be using cerr at all. For now the simplest thing to do is
change all occurrences of:
cerr << "Some text" << endl;
exit();
Should be changed to:
croak("%s", "some text");
And the need for libstdc++ goes away. This should be very easy for me
to fix. I will work on these changes over the weekend and when I
commit them to CVS, I'll email the list.
Thanks for helping out!
