The FAQ's and information at CMU say that CMUCL is for DECstations
with MACH. I don't have MACH, just plain Ultrix. Has anyone
out there built it for Ultrix? Can it be done?
CMUCL has been running on MIPS-based Decstations under Mach for years. This
was the first implementation based on the Python compiler, and it is still
the implementation that has received the most tuning. For almost as long,
DEC has been promising their customers that the would very soon be
releasing a version of Ultrix based on OSF/1 (which has the same virtual
memory machinery as Mach, more or less). Since this was always "just
around the corner" and since a port to the old bsd-based Ultrix would be a
lot of work (bsd lacks certain essential VM primitives), we decided just to
wait and let DEC catch up to us.
As you all know by now, the OSF release for MIPS-based Decstations has been
postponed repeatedly, abandoned, reinstated, and now is abandoned again.
If you are unhappy about that, complain to DEC. In any case, it is now
certain that there will never be an Ultrix port of CMU CL, unless perhaps
some outside group wants to do this. It would be a lot of work for a
machine that now is nearing the end of its useful life.
