hi, a11:
I am trying to build rtems with kbuild on linux.
just a hobby, make rtems easier to build on linux.
not support freebsd, windows...
(I guess some company don't use windows or linux,
securty is critical for them. for small companies,
e.g. shenzhen small companies, convenien is more
important.)
but this may make it hard to ship a bsp in lib.
anyway, just for fun. :D
for more infomation about kbuild building and config,
there maybe some video on youtube: compile linux kernel.

repo: (push later)
http://github.com/zhang3/rtems-kbuild

here is some build log:
