C++ and CFFI

[Daniel Papp]

Hi!

I'm interested if one can interface C++ and python code via CFFI. I'm writing an extension and I was using Cython before but CFFI seems to be a cleaner approach.

From C++ I roughly need the STL. Is it possible to do this? Am I specific enough with this question?

Thanks,

Daniel

Technically, you can, but you need to do a ritual dance for the ABI gods and sacrifice your firstborn child.

CFFI cannot access C++. You could play around with platform- and
compiler-specifc ABI like Ryan suggests; but, more cleanly, I would
recommend to wrap the C++ code into a C API first, and then call that
C API with CFFI. Of course you have to express the API in C, first,
not using things like the STL. This might be too annoying for your use case.


A bientôt,
