Help compiling Genode with other version of Fiasco.OC

[Stefan Kalkowski]

Hi,

unfortunately, using another Fiasco.OC kernel and syscall bindings for
Genode isn't supported anymore. The simple reason is: it won't work
anyway. We had to apply minor patches to the kernel, sigma0 etc. so that
Genode in general, or programs like GDB still work on top of Fiasco.OC.

Obviously, we forgot to clean up the documentation that still shows how
to use Fiasco.OC built beyond Genode's build directory. I will catch up
on it soon.

If you want to use another Fiasco.OC version, you will have to adapt the
Fiasco.OC source in Genode's "contrib" directory. Or even better, you
clone our current Fiasco.OC git repository:

  https://github.com/ssumpf/foc.git

and raise it to the version you like, not forgetting to apply the
patches that you find in branch "r56".

If you want to use a recent version of Fiasco.OC, you can also take my
branch. I've started to update our Fiasco.OC version, but did not find
the time to finish it yet:

  https://github.com/skalk/genode/tree/foc_update

Most things should work, but I've observed problems on Pandaboard, and
didn't updated L4Linux yet.

Regards
Stefan
