Both of the above are incorrect, all EPICS install directories have an
architecture component as well; you need to use these instead:
 export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$EPICS_BASE/lib/$EPICS_HOST_ARCH"
 export PATH="$PATH:$EPICS_BASE/bin/$EPICS_HOST_ARCH"

Hmm. This does of course depend on how EPICS has been installed on the
target system, and I suspect that I may have broken the rules in my
definition of how EPICS is installed on the Libera electron beam position
monitor (this is the environment Yan Ying Bing is using).
If you install EPICS as I instruct Libera users:
	1. build EPICS
	2. run install-epics on the host
	3. run libera-install-epics on the target
then the following files are installed on the *target*:
	/opt/epics/lib	<- copy of $EPICS_BASE/lib/linux-arm/*.so
	/opt/epics/bin	<- only $EPICS_BASE/bin/linux-arm/caRepeater
This is a bit non-standard, but I hope not too confusing. Of course, if
this has been done, then we need

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/epics/lib

export PATH=$PATH:/opt/epics/bin
I hope this configuration is not too deviant!
