Ernest:

It sounds like your question is the same as one I posed earlier, and Andrew's reply may be helpful:

I found that I need to have caRepeater available for my target but EPICS
BASE does not build it.
How have others done this?
We build our target as a CROSS, so caRepeater only gets built for HOST
builds.

Now for vxWorks and RTEMS, they use "repeater.cpp" which gets linked in.

What I have done for our embedded linux target is the following, is this
acceptable?
=====================================================
Modify, <BASE>/src/ca/Makefile
And added:

ifeq ($(T_A),linuxRT-x86)
  PROD_DEFAULT += caRepeater catime acctst caConnTest casw caEventRate
endif


Then, I did a build like so,
make CROSS_COMPILER_TARGET_ARCHS=linuxRT-x86


Thanks in advance for your comments and help.


Cheers,
Ernest
