wrapping C++ code using blitz++ arrays to python using SWIG

[azuri]

Hi there,
I need to use SWIG to wrap my C++ class which heavily uses blitz++ arrays to python. Has anybody done this before? I'm looking for a simple example .i file...

My imports in CFits.h:

  #include <stdio.h>
  #include <iostream>
  #include <cstdlib>
  #include <blitz/array.h>
  #include <blitz/vector.h>
  #include <blitz/vector-et.h>
  #include <blitz/vecwhere.h>
  #include <blitz/tinyvec.h>
  #include <blitz/tinyvec-et.h>
  #include <fitsio.h>
  #include <fitsio2.h>

My stelladrp.i file:

%module stelladrp
%{
#include "cfits/src/CAny.h"
#include "cfits/src/CFits.h"
#include "mextract/src/MExtract.h"
%}
%include std_string.i
using std::string;
%include "cfits/src/CAny.h"
%include "cfits/src/CFits.h"
%include "mextract/src/MExtract.h"

my commands:

swig -c++ -python -I/usr/local/include -I/usr/include stelladrp.i
g++ -lm -fpic -std=c++11 -c mextract/src/MExtract.cpp stelladrp_wrap.cxx -I/usr/include/python2.7/
g++ -shared MExtract.o stelladrp_wrap.o -o _stelladrp.so

my Python output when importing stelladrp:

>>> import stelladrp
