Hi,

Thanks Ray.

I have sorted out the links problem but I've now hit another one. EMC tries
to start but tells me almost immediately that 'sim.o (or steppermod.o or any
of the others) was compiled for kernel version 2.2.14-rtl2.2 while this
kernel is 2.2.14-rtl2.3'
Is there anything I can do about this - other than going back to an earlier
version of rtlinux? I noticed that Terry says he has EMC running on the
2.4.* kernel but I didn't save the message. Was this on a recent version of
rtlinux and, if so, what was changed in EMC?
