Question

Hey all. I’ve downloaded and moved the Xerces (v3.1.1) source here: /usr/include/xerces and I can see the source in the project explorer like this:

MyCppProject

• Binaries

• Includes

  • […] // some other directories

  • xerces

    • dom

    • […] // some other directories

And, here’s my simple C++ code:

#include <xercesc/util/PlatformUtils.hpp>

using namespace xercesc;
#include <iostream> 
using namespace std;
int main(int argc, char* argv[])
{
  try {
      XMLPlatformUtils::Initialize();
  }
  catch (const XMLException& toCatch) {
      return 1;
  }
  XMLPlatformUtils::Terminate();
  return 0;
}

And, here's the error that I get (along with others that are caused by this file not being included):

../main.cpp:1:42: error: xercesc/util/PlatformUtils.hpp: No such file or directory

What I don't understand is how the relative paths work in the source file. When I say type

#include <xercesc/util/PlatformUtils.hpp>

where is it looking, if not on the include paths already listed in the project explorer?

Answer 1

From what you state in your question it looks like your using the folder name ‘xercesc’ instead of ‘xerces’ in your include path.

try

#include <xerces/util/PlatformUtils.hpp>

The include directive will look in all of the directories in the include path and try to find the file specified. So if you specified a folder c:/something/include in your include path. it would search for c:/something/include/xercesc/util/PlatformUtils.hpp.

If your file can’t be found then you need to check the include paths being used.
