[IronPython] Using a c library as a dll or assembly

[Anders Elfgren]

Hi, 
 
First let me say that I'm new to Iron Python, but at least I've read
this in the FAQ.. :)
 
Q: How do I build and call into PYD libraries?
A: IronPython does not support using PYDs built for CPython since they
leverage implementation details of CPython.  You can get a similar
effect for new "PYD"s you would like to implement by writing them in C#
or VB and building a DLL for .NET.
 
That said, I've got some questions to see if what I'm doing is possible
anyway.
 
We've got a c library of which most of the code has also been written in
Python. We want to create an editor using .net forms which we can use to
edit some files, and to do that we need some data structures that exist
in this library. 
 
My current idea is to interface against the python library using
IronPython, and then accessing the datastructures through that in C#
(although if absolutely necessary, we could write the editor in
IronPython too). The thing that is standing against me now is that one
function that exists a small C dll. Since IronPython can't access this
(unless this has changed since the FAQ was written?), I was thinking
that maybe I can compile the dll using the /clr flag and thus get a .net
assembly. Would I then be able to use the function?
 
The Python code just tries to import it:
import AvHash
 
And then use it..
def AdfHash(str):
    return AvHash.HashString(str)
 
 
At the import statement, this error is raised:
Traceback (most recent call last):
  File X:\ctg\libs\ADF\main\common\modeditor.ipy, line 20, in Initialize
  File , line 0, in __import__##4
  File X:\ctg\libs\ADF\main\common\AdfLib.py, line 1, in Initialize
  File , line 0, in __import__##4
ImportError: No module named AvHash
 
 
 
Or is there some other solution? I've just started researching how to
interface between C/C#/Python/IronPython so there may well be things I
haven't heard of...
I hope I've made my problem clear, thanks for any responses. :)
