Error Starting Argus Daemon

[Carter Bullard]

Hey Neal,
Best I can do in interpreting the error, is that EPERM is being returned as the error
code for the call to pthread_create(), which is an error with permissions on setting the
scheduling priority of the ArgusOutput thread.   

The scheduling assignments are done in argus.c, around line #605.
One way to get past this is to comment out all the scheduling logic, and see if
we get farther.  To do this, apply this patch:

==== //depot/argus/argus/argus/argus.c#90 - /Volumes/Users/carter/argus/argus/argus/argus.c ====
605a606
> #ifdef ARGUS_NOT_DEFINED
635a637
> #endif

which says add an ' #ifdef ARGUS_NOT_DEFINED ' to line 605 in your ./argus/argus.c, which will be false,
and close the logic with an #endif on line 635.  This basically comments out all references to pthread_attr_getschedpolicy()
and pthread_attr_setschedpolicy() calls in the code.

After you comment out this and compile, you should get farther?

Hope all is most excellent, and sorry for the inconvenience,

Carter
