Hi,
I'm trying to use the Python C API but I have
a problem when importing my new module.
Here is my (short) code:
#include "Python.h"
long sumList(PyObject *list) {
int i, n;
long total = 0;
PyObject *item;
n = PyList_Size(list);
if (n < 0) return NULL;
for (i = 0; i < n; i++) {
item = PyList_GetItem(list, i);
if (!PyInt_Check(item)) continue;
total += PyInt_AsLong(item);
}
return total;
}
PyObject *wrap_sumList(PyObject *self, PyObject *args) {
PyObject *list;
PyObject *total;
if (!PyArg_ParseTuple(args, "0&", &list)) {
return NULL;
}
total = Py_BuildValue("l", sumList(list));
return total;
}
static PyMethodDef exampleMethods[] = {
{"sumList", wrap_sumList, METH_O},
{NULL}
};
void initexample() {
PyObject *m;
m = Py_InitModule("example", exampleMethods);
}
My compilations lines:
gcc -Wall -fpic -c -I/usr/include/python2.4 -I/usr/lib/python2.4/config
mytest.c
gcc -shared mytest.o -o examplemodule.so
When I try to import examplemodule, I obtain the following message:
>>> import examplemodule
Traceback (most recent call last):
File "<stdin>", line 1, in ?
ImportError: dynamic module does not define init function
(initexamplemodule)
Someone has an idea ?
Thx,
Marc.
