  In order to cross-compile Linux kernel i have to patch host-side tools a
little bit. Current problems are:
  1. Cygwin misses linux/types.h
  2. Cygwin defines the following ELF macros according to host machine:

linux/types.h (for __u8. __u16, etc), and omit ELF definitions. AFAIK they
are not used anywhere, they are just inherited from BSD.
  At the other hand, i believe the same problem will happen if i try to
cross-compile Linux kernel under BSD. And Cygwin is BSD-style system...
I have no opinion on the ELF definition issue, but just adding a
linux system header looks pretty wrong to me.


There are far better ways to cross-compile the Linux kernel. I built a Cross Linux From Scratch system under Cygwin earlier this year. I just got back from vacation, though. Give me a day or so, and I'll find my notes on it. I believe most of them have already been posted here in the past, however.
