RE: [CAD_CAM_EDM_DRO] Re: June 7 EMC install problems

Ray,

Ok, I'll try moving back to the rtlinux 2.2 release instead of the 2.3
version I have. I did not need some of what your instructions called for,
specifically the fpermissive command. I still had to copy files all over
the place the get rid of the 'not in' errors of which there were plenty. I
still have not gotten tkemc to work but that is another issue. At least
from what you tell me I should have a reasonably functional EMC. I'll check
it out further.

Thanks

John Guenther

The good news is that iosh isn't needed by anything but a script called
ioshow and an emcio clone called tkio.

More good news is that you might try discarding all of my EMC install
instructions because the compiler with RH 6.2 seems to be in tune with the
way that the EMC was written. Fred Proctor posted a brief report on 6.2
install on emc@... in which he said.

X-To: emc@...

EMC folks,

I just built the EMC for RTL 2.2 yesterday. Here are my observations:

1. I used Red Hat 6.2, which is kernel 2.2.14.

2. I got the prepatched kernel source from rtlinux.org, for the 2.2a
patch. I think this may be a patched 2.2.13 kernel; anyone know? I'm
using linux_2_2_14/rtlinux_2_2 as the plat names for this.

3. The default build (do nothing during the "make xconfig", just save
and quit) compiles for SMP. This will define APIC_BASE, or something
like this, that is needed at some point during the EMC compile. If
you're getting this error during the EMC compile, set the SMP option
during "make xconfig"....

4. The latest EMC release had a problem with steppermod.o and the PERIOD
flag. During the insmod, a "parm_PERIOD" error popped up. This was due
to a missing line in emcstepmot.c, which is correct in emcmot.c. Just
above init_module(), you should have:

MODULE_PARM(PERIOD, "i");
MODULE_PARM(SHMEM_BASE_ADDRESS, "l");
MODULE_PARM(STG_BASE_ADDRESS, "h");
MODULE_PARM(PARPORT_IO_ADDRESS, "l");

The first one, for PERIOD, was omitted in emcstepmot.c. I put it in but
it's not in the release yet.

I built this for a laptop and was able to bring up the EMC, take it out
of estop, and jog.

-------------

Hope this helps.

Ray
