first time use of swig, python and c++ .. it's a mess ... pleaseadvice

[Eric von Horst]

Hi,

we have a third-party product that has a C++ api on HP-UX.

I would like be able to use the API in Python (as I remember Python is
good at doing this).

I have no experience with this so I Googled and tried to find some
info on what I had to do.

So, I installed Python 2.4.4 and Swig 1.3.33

The header file to the library is '/opt/OV/include/opcsvcapi.h'.

I created a SWIG file with the following content:
"
%module opcsvcapi
%{
/* Includes the header in the wrapper code */
#include "/opt/OV/include/opcsvcapi.h"
%}

/* Parse the header file to generate wrappers */
%include "/opt/OV/include/opcsvcapi.h"
"
Then I ran the cmd:
# swig -c++ -python opcsvcapi.i
with output:
"
/opt/OV/include/opcsvcapi.h:41: Warning(362): operator= ignored
/opt/OV/include/opcsvcapi.h:46: Warning(503): Can't wrap 'operator
Type' unless renamed to a valid identifier.
"

The result are two files:
opcsvcapi.py
opcsvcapi_wrap.cxx
I created a 'setup.py' file with the following content:
"
import distutils
from distutils.core import setup, Extension

setup(name = "opcsvcapi",
version = "1.0",
ext_modules = [Extension("_opcsvcapi",
["opcsvcapi.i","opcsvcapi.cxx"])])
"

Then I run: python setup.py build

This results in an extra file:
opcsvcapi_wrap.c and a 'build' directory

and the following errors:
"

running build_ext
building '_opcsvcapi' extension
swigging opcsvcapi.i to opcsvcapi_wrap.c

"

and that's it.
Any idea what I am doing wrong?

Any help much appreciated
