However, I used to cross-compile the Linux kernel from Solaris on Sparc to Intel. I just had to: 1) Get the relevant headers and libraries on Solaris 2) Deal with the byte sex issues - Sparc is Big Endian, Intel is Little Endian 3) Natively compile a little bit of code that was needed by the build process You appear to be aware of #1. You probably won't need to worry about #2, since you're going Intel -> Intel. #3 could be an issue for you, but it's just a matter of using two different compilers for some different parts of the build process - one native, one cross. I'd try a little hello world first, then worry about your larger project. You could also put some feelers out about Cython and Pybind too, to see if they've been used for cross-compilation before. If yes, you're probably in like Flynn, otherwise it could potentially turn out to be a big project. If cross-compilation doesn't work out, you could probably set up a Windows virtual machine with an sshd, and build on that. Either way, you may find Wine useful for testing.
