Re: Cross-compiling chicken crunch from linux to windows

Yeah, I've been using w64devkit, it's been pretty great actually.
Also, I think in terms of having a cross platform fmemopen, this is probably your best bet
https://github.com/Snaipe/fmem
It's MIT licensed (yay!) but uses CMake (boo!)

I haven't tried CRUNCH on Windows yet, but it _should_ normally work, but as
you can see above, the "fmemopen" libc call doesn't seem to be available
on Windows. I don't know if there is a replacement in the win32 API,
if you find one, please don't hesitate to send patches or suggestions to
me or this list.

I strongly recommend w64devkit, at least we can try to reproduce any
issues you find. The mingw32 toolchain landscape is a mess and one
never knows which version supports what. So please consider using
w64devkit, at least when testing code that you need help on.
