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:
/home/sinclair/rtemsEpics/supTop/R3.14.9/base/lib/RTEMS-mvme2100//libCom.a(devLibOSD.o):
In function `rtmsDevInit':

../../../src/libCom/osi/os/RTEMS/devLibOSD.c:105: undefined reference to
`bspExtInit'

/home/sinclair/rtemsEpics/supTop/R3.14.9/base/lib/RTEMS-mvme2100//libCom.a(devLibOSD.o):
In function `rtmsDevWriteProbe':

../../../src/libCom/osi/os/RTEMS/devLibOSD.c:253: undefined reference to
`bspExtMemProbe'

/home/sinclair/rtemsEpics/supTop/R3.14.9/base/lib/RTEMS-mvme2100//libCom.a(devLibOSD.o):
In function `rtmsDevReadProbe':

../../../src/libCom/osi/os/RTEMS/devLibOSD.c:234: undefined reference to
`bspExtMemProbe'
---------------------------
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?
