Re: EPICS on RTEMS

[John Sinclair <sinclairjw@ornl.gov>]

I guess I was missing this piece. I had to manually copy the library 
(could have soft-linked it) and add

USR_LIBS += bspExt

to the makefile. But then, since make is being instructed (why?) to also 
build the system on the host (linux-x86), this library
was missing for the linux build. I created a dummy one using ar and the 
build finally succeeded.

Is this the "correct" way to do EPICS with RTEMS or do I somehow have 
things half-configured?
