program compiling errors

[Deephay]

Greetings all,

  I am just started to work with the parsing API for C++, I got some code and try
to compile it, but I got some strang errors here:

and here's the code:#include <xercesc/dom/DOM.hpp>
#include <xercesc/parsers/XercesDOMParser.hpp>
#include <xercesc/util/XMLString.hpp>
#include <xercesc/util/PlatformUtils.hpp>
#include <xercesc/sax/HandlerBase.hpp>
#include <iostream>

XERCES_CPP_NAMESPACE_USE
using namespace std;

int
main(void)
{
        XMLPlatformUtils::Initialize();
        XercesDOMParser *parser = new XercesDOMParser();
        DOMDocument *myDoc;
        DOMNode *aNode;
        DOMText *someText;
        parser->parse("tutor.xml");
        return(0);
}

What is the problem here? thx very much!
