[Ironpython-users] cython-for-ironpython

[Markus Schaber]

Hi, Pawel,

IronPython has completely different inner workings than cPython. It uses .NET and the DLR infrastructure (memory management, objects, etc..) instead of the C-implemented Infrastructure provided by cPython.

Two projects tried to bridge the gap between cPython and IronPython / .NET

https://code.google.com/p/ironclad/: Import cPython extensions in IronPython, this is what could match your "mapping dll" requirement.)

http://pythonnet.sourceforge.net/: Allows cPython code to call into .NET code.

Both projects look rather dormant nowadays.

So it is not easily possible to use output compiled by cython within IronPython.

The same applies to Jython and some other alternative implementations.

On the other hand, IronPython and the DLR provide powerful Just-in-Time capabilities, so you may get the desired speed without actually using Cython.


Best regards

Betreff: [Ironpython-users] cython-for-ironpython

Hi,
I am trying to get hello world with cython. I took a simple cnumop.cpp from tests and run:
ipy cython.py --dotnet tests/compile/cnumop.pyx
The resulting file (cnumop.cpp) is now part of project (cpp/clr/class library).
After resolving usual reference dependencies I hit: PyErr_Format
Since this is a symbol which is coming out of cpython, I am looking for equivalent in clr world.
I looked in cython itself but found nothing (mapping?)
Is there some sort of mapping dll (cpython symbols => iron symbols)?
Or perhaps I am doing something wrong when invoking cython?

Any help or information about this is greatly appreciated.
