Re: EMC and Red Hat 8.0

Hi Sivaraj

I may be jumping into this out of turn but I had several thoughts while 
looking through your terminal file.

The first is that sim will run without any real time committments.  Any 
of the run files that require real time will test out that part of the 
system as well as the central EMC task and interpreter stuff so it is not 
surprising that sim will go but emc.run will not.

There are some variable name changes that were built into the ini file 
recently and it would appear that these are raising some warnings.

STG_BASE_ADDRESS has largely been replaced with IO_BASE_ADDRESS but the 
steppermod that you are using does not recognize that change.  I'd either 
bring your version of steppermod forward, or your ini backwards.  
Steppermod is just a bit of a problem with rtai still.  It is better than 
it was but freqmod is a much better choice still.  If you need the 
binning algorythm from steppermod you can specify a stepping type in the 
ini file.  This variable is demonstrated in the stepper.ini in the 
repository right now.

You could simply comment out this variable.

I'd switch to minimillio and minimilltask for a first run because they 
are less demanding with regard to e-stop and such.

I believe that this problem may be caused by a defective var file.  Look 
in the one that you are using and see if 5220 is set to 1.0000.  This 
variable tells the interpreter which of the ten coordinate systems to 
start with.  If it is not set to 1, or if there are a bunch of text 
comments in the file, copy stepper.var to overwrite the one you had used.

Hope this helps.
