SWIG callback problem on win32

Hi,

I tried to build the swig: callback example,
but when I run the runme.py file I get a message box:
abnormal program termination

The error appears in already in the first line of the python
callback generation:

# Add a Python callback (caller owns the callback, so we
# disown it first by calling __disown__).

caller.setCallb ack(PyCallback( ).__disown__())
caller.call()
caller.delCallb ack()

When I call only PyCallback().__ disown__()
alone, the error appears, too.

Anybody knows a solution?

Thanks a lot,

Markus

I made a new trial:

The error appears in the following line of the
Callback class:
_camera_callbac k.disown_Callba ck(self)

I guess the problem is in the
static PyObject *_wrap_disown_C allback
function?
How could I get rid of it?

Thanks for any hints to get rid of this error.

Markus

PS
The application is a C++ Thread providing a callback function,
when a new camera image on the firewire bus is available.
Then I want to inform a python object that it can fetch the new
image data.

I'm attempting to follow the instructions at http://sebsauvage.net/python/mingw.html, without luck. I have Python 2.3, MinGW 3.2.3, ans SWIG 1.3.19. I get an export error on "initexample" when attempting the example. Do I need some extra switches to get SWIG to create that function? Or is it something else? Here's my example build:

Hi, I'm using Python in my win32 app by linking to the python23.dll.

I create a MyModule.i file for swig which contains a simple test c++ class. I run swig on it with the following options: swig -python -c++ -includeall -shadow MyModule.i,...

Hi together, i have a Windows DLL in C that is internally multithreaded and provides a callback function to signal specific events. As I understood one can use "normal" C-code with swig. Is it also possible to use existing DLLs? Does swig can also handel the callback method? If not - is there another wrapper toolkit that can do that? Thanks, Peter

Hi, I'm using Cygwin and ActiveState perl to try to compile a sample application using SWIG. I'm using the short tutorial from http://www.swig.org/tutorial.html (the perl part of it), but with a simplified version of their example (just a void hello() {printf("Hello, world!\n");} and corresponding .i interface file, %module hello \ extern void hello();). I first do swig -perl5 hello.i which works fine.

Hello, I spent the morning figuring out how to use SWIG on Microsoft Windows. I compiled the example from the SWIG tutorial on http://www.swig.org. The biggest stumbling block was not knowing that I needed to rename the DLL created to have a PYD extension. I also ended up writing a .def file for exporting functions from the DLL. Here is my SConstruct file for using SCons to build the library. It is not perfect, but it should be...
