Hello,
attach is git patch which provides basic OpenBSD support to the RTEMS
source builder. The only issue so far (and I've not got that far) is
that rtems tools, precisely libelf is broken and compilation fails
because of it with:
[ 7/235] Compiling rtemstoolkit/elftoolchain/libelf/elf_end.c
In file included from ../rtemstoolkit/elftoolchain/libelf/elf.c:27:

../rtemstoolkit/elftoolchain/libelf/elf.c:36: error: 'LIBELF_CLASS'

positive thing is that upstream version of elftoolchain project already
supports OpenBSD and I've tested the libelf is buildable on it, so it's
perhaps "just" of the matter of updating to what upstream provides?
To reacap current status: iconv is not used in newlib due to issue with
big5 encoding (configure complains about it). GDB is build w/o python
since linking against libpython on OpenBSD fails for so far to me
unknown reason. I hope both those limitations are not show-stoppers so
when elftoolchain issue is solved I'd rather continue to see if I'm able
to build whole RTEMS tool chain.
Thanks,
Karel
