SWIG: name 'new_doubleArray' is not defined

[alexandre_irrthum at yahoo.com]

Hello,

I am trying to use SWIG (1.3) to wrap some C code in Python (2.3.5)
under Linux, but obviously I am missing something with arrays.

This is my example.c file:

double sum_array(double x[], int size) {
        int i;
        double sum = 0.0;
        for (i=0; i<size; i++) {
                sum += x[i];
        }
        return sum;
}

This is example.i:

%module example
%include "carrays.i"
%array_functions(double, doubleArray);
%{
extern double sum_array(double x[], int size);
%}
extern double sum_array(double x[], int size);

These three command seem to work fine:

swig -python example.i
gcc -fPIC -c example.c example_wrap.c -I/usr/include/python2.3
ld -shared example.o example_wrap.o -o _example.so

In python, I can import the module:
>>> import example

But this fails:
>>> a = new_doubleArray(10)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
NameError: name 'new_doubleArray' is not defined

What am I doing wrong ?

Thanks for your help.
