cross-compiling -- creating .pyd under linux

[Yoav Goldberg]

Hi,
While not a cython question per-se, I do need it primarily for cython.

I have a few cython modules which I would like to use both on linux
and windows. I develop mainly under linux, compiling with gcc. I
would like to build the windows modules (.pyd) directly under linux,
if possible. In fact, it would be best if I could just issue one
script that will build the executables for both platforms (adding in
the possiblity for osx will be a welcome addition as well). Is that
possible in any way?

thanks,
Yoav

I have no idea--you're probably better off asking on the distutils
list. Perhaps you could do something with wine (I'd imagine you'd need
Win32 headers and libraries to link against at least)?

Hi,

I've just built some cython windows binary distributions on OSX using wine:

- stealing the idea from the Numpy instructions. I installed the
latest mingw into wine and built that way. I guess it will be
possible in linux too, I should check. If you get anywhere, will you
mail the list so we can follow your footsteps?

Thanks a lot,

Matthew

Thanks,
I will have a look at your suggestion, though I am not very
enthusiastic about wine.. was hoping gcc could do it natively with a
suitable back-end. I will ofcourse update if I make any progress.

I bet you'll have it a lot easier with wine than trying to get all
dependencies (Python, header files, etc.) properly built and set up for
cross compilation.

Hi,

Yes, I agree - I suspect it would be a huge amount of unhappy work to
get cross-compilation to work with the distutils build machinery.

Best,

Matthew
