Never had a problem here... I even cross compile from Mac OS X.  Just gotta
use the right version of the compiler.  [Stupid, I agree, and circle gets
the square]

See this for some potential hints... Of course it's PPC specific but it may
help you figure out why stuff won't build in general.

Been a while since I've tried this myself but I was very successful back
then [1.5 years ago?]

- get L4KA to boot linux (predicated on previous step)


I think I only ever ran a Live CD of this... but it worked great with the
Dresden Realtime OPerating Systems demo floppy or CD or whatever it was...
They have a really weird windowing system for launching Debian on L4
instances.... this was quite a bit before Xen mind you and they were doing
the same things but on a microkernel that had less suck than mach.

- run Plan 9 as an L4KA guest (predicated on previous step)


I'd try that :)  The weird thing is you can load l4-linux and then write an
OS personality in another address space and use the L4 messaging to use
linux as something of a driver repository.  There are even some performance
measurments of the impact of this, which is a ton better than trying to
write drivers in userspace with mach.  I wouldn't try 10Gbit ethernet that
way but for disks and some other devices this seems to work kind of well.

Abstract here:

Sometimes I wish I could just get paid to play with esoteric weird OS junk
all day.

  so far, failure all around.

yep, I'm at least glad that I see more and more -std=c99 in the FreeBSD
build system.  Less and less gcc-isms is a big plus, even if I don't care
for C99 so much [which could be worse].
