Distutils on windows with mingw, messed up includes?

Hi,

I am pretty lost here: My goal is to get an existing c++ library wrapped using distutils and swig. My C++ knowlege is very limited (so is my Python).

So I started with trying to wrap a single class from the library (I already have a simple example .cpp file packed into a .pyd correctly and it works fine with ipython) but when trying to do the same with this one:

Code:

#include "jcnError.h"

jcnError::jcnError(const string& message, const ErrorType& errorType)
: std::runtime_error(message), mErrorMessage(message), mErrorType(errorType)
{
}

const char* jcnError::what(void) const throw()
{
	return std::runtime_error::what();
}

jcnError::~jcnError(void) throw()
{
}

I get an error from gcc: "iostream: no such file or directory". The includes are where they are supposed to be and with the -v option gcc tells me that it searches there as well, so what is the problem?

Here is the header:

Code:

#pragma once

#include <iostream>
#include <string>
#include <stdexcept>

using namespace std;

#define jcn_DEBUG /**< If this is defined more error messages will be thrown */

/**
* Internal type of error
*/
enum ErrorType 
{
	WARNING,
	EXCEPTION,
};

/**
* @class jcnError
* @author Jan C. Neddermeyer
* @brief jcnError is inherited from the std error class runtime_error
*/
class jcnError :
	public runtime_error
{
public:
	/**
	* Constructor
	* @param message error message, should provide detailed information where and why an error has been thrown
	* @param errorType optional error type
	*/
	jcnError(const string& message, const ErrorType& errorType = EXCEPTION);

	/**
	* @return error message, corresponds to the what() method in runtime_error
	*/
	virtual const char* what(void) const throw();

	/**
	* @return error message as std::string
	*/
	inline const string GetMessage(void) const {return mErrorMessage;};

	/**
	* @return error type
	*/
	inline const ErrorType GetErrorType(void) const {return mErrorType;};

	/**
	* Destructor
	*/
	~jcnError(void) throw();

private:
	string mErrorMessage; /**< error message */
	ErrorType mErrorType; /**< error type */
};

and here my setup.py

Code:

import distutils
from distutils.core import setup, Extension

module=Extension('_bpetest',sources=['bpe.i','jcnError.cpp'],include_dirs=['C:/users/kevin/Desktop/bpe_demo/src'])

setup(name="bpetest", version="3.2", ext_modules=[module])

and finally the bpe.i:

Code:

%module bpetest
%{
#include "jcnError.h"
%}

all help appreciated,

thanks,

Kevin
