We build our target as a CROSS, so caRepeater only gets built for HOST builds.

Was there something which required this?


Yes, our embedded linuxRT target was complaining at the IOC console.

Messages were like so,
=========================================================
epics> CA client library is unable to contact CA repeater after 50 tries.
Silence this message by starting a CA repeater daemon
or by calling ca_pend_event() and or ca_poll() more often.

After building caRepeater for my embedded target, all is well now.
The default EPICS BASE build does not do this.
I had to change the Makefile in  "<BASE>/src/ca"

Embedded target is happy now. :)


Cheers,
Ernest
