Re: [Py2exe-users] create dll from module?

Hi,

So in fact you will be embedding Python in the .NET app.

You will need to do a lot more than you are trying to do below. I would sug=
gest looking at Pyrex to create some C code that will create the required D=
LL exported functions/classes (though I don't think there are tools to auto=
matically take the Python code and create a Pyrex or C wrapper for it).

Some hints (though maybe I should write up what I have done a few times :)
 - You need to initialize Python AND your module in the LibMain method
 - The Pyrex functions will just forward their calls to the underlying Pyth=
on code (e.g. if there is a function paramiko.DoSomething(arg1, arg2, arg3)=
, then your Pyrex code should have a similar function and just call the par=
amiko function.
 - If a paramiko function uses duck typing or allows you to pass in differe=
nt types for a parameter then you will need to decide which signature to ex=
pose to .NET  (or even create multiple functions to make all available - if=
 that was necessary). Remember that C (and thus DLL functions) have no over=
loading/duck typing.
 - Is paramiko pure python? (it seems it is from their home page) so it mig=
ht be easier to do something with IronPython or Python.NET (though I am not=
 sure about how well those allow you to make stuff available to other .NET =
languages - maybe they just let python access other .NET components).

Sorry - it's 6:30 in the evening just before thanksgiving (though I am not =
American, I live here) and the office is empty and I feel tired ;)

If this is something you wish to pursue - then I can try to help you,
Thanks
  Mark

Subject: [Py2exe-users] create dll from module?

How can I create a dll from a python module?  I need to make the
interface of paramiko (a third party sftp module at
http://www.lag.net/paramiko/) visible to a coworker's dotnet code, so I
want to convert the module (and its dependencies) into a dll.

I thought the ShippingEmbedded page (under tips and tricks) might help.
  It says to create a module-less setup.py:

from distutils.core import setup
import py2exe
setup()

and then include the module on the commandline; in my case:

python setup.py py2exe --includes paramiko

but the resulting dist folder had no 'paramiko.dll'.  I assume the code
I want is sitting in library.zip.  Is there a way to expose it as a dll?

Thanks,
John
