Re: Requesting advice on weather to use L4Linux or Wombat

Robert:

L4 is a microkernel specification; there are two main implementations
of that specification:

Fiasco and L4Ka::Pistachio; as long as I know, Fiasco implements an
older specification of L4.

On top of Fiasco, there is L4Env that is a set of libraries to turn
the work with the kernel easier, and on top of L4Env is L4Linux...

The same thing happens with Pistachio, on top of Pistachio there is
Kenge (a set of libaries to make the work easier), on top of Kenge is
Iguana (an OS personality that provides a set of services to enable
the developer to work with memory management, process protection,
etc.); and on top of Iguana is Wombat.

That's all I can say you... I do not know what implementation is
better and why, but Fiasco/L4Env/L4Linux are easier to build (they use
standard CVS and make tools); Pistachio/Kenge/Iguana/Wombat use Bazaar
and SCons.

Regards,



Ernesto
