Problem with Apache XML C++ Parser library

Ok, I try to make application using xml library. My configuration data will be stored in xml files. So....
I downloaded library from here:
http://xml.apache.org/xerces-c/index.html

Ok, I have unpacked it to here:
/home/gandalf_bar/
So the library files are here:
/home/gandalf_bar/xerces/include

I have put the libraries to LD_LIBRARY_PATH so I can run the example without problem.

But I don't know how to compile one single application with this library. I try to read the document. But I cann't find it.

Consider this simple code:

Code:

---

#include <xercesc/parsers/XercesDOMParser.hpp>
#include <xercesc/dom/DOM.hpp>
#include <xercesc/sax/HandlerBase.hpp>
#include <xercesc/util/XMLString.hpp>
#include <xercesc/util/PlatformUtils.hpp>
#include <iostream>
using namespace std;

int main( int argc, char* argv[] )
{
  try
  {
      XMLPlatformUtils::Initialize();
  }
  catch( const XMLException& toCatch )
  {
      char* message = XMLString::transcode( toCatch.getMessage() );
      cout << "Error during initialization! :\n"
          << message << "\n";
      XMLString::release( &message );
      return 1;
  }
}

---

When I do this:
$ g++ hello.cpp -o hello
hello.cpp:1:47: xercesc/parsers/XercesDOMParser.hpp: No such file or directory
hello.cpp:2:42: xercesc/util/PlatformUtils.hpp: No such file or directory
hello.cpp:3:38: xercesc/util/XMLString.hpp: No such file or directory
hello.cpp:4:31: xercesc/dom/DOM.hpp: No such file or directory
hello.cpp:5:39: xercesc/sax/HandlerBase.hpp: No such file or directory
hello.cpp:6:38: xercesc/util/XMLString.hpp: No such file or directory
hello.cpp:7:42: xercesc/util/PlatformUtils.hpp: No such file or directory
hello.cpp: In function `int main(int, char**)':
hello.cpp:15: error: `XMLPlatformUtils' undeclared (first use this function)
hello.cpp:15: error: (Each undeclared identifier is reported only once for each
function it appears in.)
hello.cpp:15: error: parse error before `::' token
hello.cpp:17: error: parse error before `&' token
hello.cpp:21: error: `message' undeclared (first use this function)
hello.cpp:22: error: `XMLString' undeclared (first use this function)
hello.cpp:22: error: parse error before `::' token
hello.cpp: At global scope:
hello.cpp:25: error: parse error before `}' token

But if I do this:
$ g++ -o hello hello.cpp -I /home/gandalf_bar/xerces/include
hello.cpp: In function `int main(int, char**)':
hello.cpp:15: error: `XMLPlatformUtils' undeclared (first use this function)
hello.cpp:15: error: (Each undeclared identifier is reported only once for each
function it appears in.)
hello.cpp:15: error: parse error before `::' token
hello.cpp:17: error: parse error before `&' token
hello.cpp:21: error: `message' undeclared (first use this function)
hello.cpp:22: error: `XMLString' undeclared (first use this function)
hello.cpp:22: error: parse error before `::' token
hello.cpp: At global scope:
hello.cpp:25: error: parse error before `}' token

So is there anyone outthere have experience using this xml parser library and want to help me compiling the application using this library?

Thank you.

Well, since it apparently doesn't like your path, how about using the whole path?

Code:

---

#include "/home/gandalf_bar/xerces/include/whatever/whatever/whatever.hpp"

---

As a general rule, take the very first error or warning, fix it, and attempt your compile again. Repeat until you've got no errors and warnings.

Quzah.

Got it! I have to do this way:
g++ -o hello hello.cpp -I /path/to/include -L /path/to/lib -lpthread -lxerces-c

And in the file I have to put this statement:
XERCES_CPP_NAMESPACE_USE

Very confusing.
Thank you.
