For what it's worth, I get a very similar error when the epics build  
process is in softIoc:
( i'm compiling on darwin-ppc, EPICS 3.14.8.2, and using RTEMS from  
the HEAD cvs branch)

And yes, I added OP_SYS_CFLAGS += -DOMIT_NFS_SUPPORT to os/ 
CONFIG_SITE.Common.RTEMS

It looks like librtemsNFS is being linked against regardless of the  
previous setting...

Any ideas ??

BTW -- Eric, you may want to change OMIT_NFS to OMIT_NFS_SUPPORT in  
your EPICS/RTEMS tutorial. I thought that may have been causing the  
linking error, but that isn't the case...
