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?

Sounds like you're missing Till's 'BSP Extensions' library.

The EPICS build system fragment
configure/os/CONFIG.Common.RTEMS-mvme2100 should probably be changed
add -lbspExt to the list of libraries.

I am beginning to do some VME access from an EPICS application on
RTEMS. As a first check, I

added a bit of vme access code to a device support function only to
see if the application would

build. The code merely calls devRegisterAddress using atVMEA16 as the
address type.
The build fails with the following errors:

---------------------------
I have built an application using the generic RTEMS build scheme (no
EPICS) that accesses the VMEbus without problems.
Any ideas as to what configuration pieces are missing?
