[PythonCE] building a 'simple' example

[Luke Dunstan]

Hi,

I built your example simple.pyd and the only problem was that at first 
Python reported the error:

    Error: dynamic module does not define init function (initsimple)

The solution was to declare it properly by adding extern "C":

    extern "C" DL_EXPORT(void) initsimple()

This may not be related to your problem though. Anyway, after this change it 
worked fine. Please post more information about how you built the DLL (e.g. 
the project files), what SDK you used, and how you configured it to use the 
Python headers and libraries.

Luke

Hi,

Thanks for saying with me, The "simple" example is at the bottom of the 
thread(and this mail). The .py program that calls it is:

import simple

but ceaches with:
ImportError: DLL load failed:The specified module could not be found.

I would feel very foolish, but if I need more than that, than I am totally 
unawhare of it. I must admit I am a bit out of my league here.

Thanks for your toughts.
