Re: EMC-programming

Hi,

I've been trying to understand the startup files for EMC and have been
playing with some of the example files included in the download. I have
found that the first reason they don't run 'as is' is that they point
the 'insmod' command to a '/plat/linux/' directory which does not exist
if you use the rtlinux09J version. This names the relevant directory
'/plat/rtlinux_09J/'. Changing the entry in the 'emc.run', 'shvbase.run'
etc. files does start them off but they almost immediately give a series
of errors as follows:

installing motion modules
plat/rtlinux_09J/lib/minimod.o: unresolved symbol rt_task_make_periodic
plat/rtlinux_09J/lib/minimod.o: unresolved symbol rt_task_delete
plat/rtlinux_09J/lib/minimod.o: unresolved symbol rt_task_init
plat/rtlinux_09J/lib/minimod.o: unresolved symbol rt_task_wait
plat/rtlinux_09J/lib/minimod.o: unresolved symbol rt_task_use_fp

I get the same errors if I try to change to using 'steppermod.o' instead
of 'minimod.o'.
Both the latter files only read as hex in emacs and so I assume they are
compiled. Can anyone explain what they are and what the errors denote
please?

Best wishes

Ian
