Ok, your Linux system doesn't have the /usr/lib/libreadline library 
installed, which I guess we assumed that all Linuxes would have.  The 
simplest answer would be to tell you to install that using the relevent 
RPM (or whatever package system your linux version uses), but there are 
several versions of the readline library on our systems here and I'm not 
sure which version we use/need.  I suspect it's the .so version though if 
you want to try installing a suitable package containing that.

For other OSs where libreadline isn't available there is an emulator 
included in the EPICS code, but to switch to that you'd need to modify the 
configuration and possibly some of the Makefiles, and I'm not the best 
person to handle that kind of issue, so I've copied this message to Janet 
Anderson, who is the expert on the build system.


Janet,

what's the simplest way to resolve this?  Will ld be looking for 
libreadline.a or one of the .so versions (which are in different Linux 
RPMs on Red Hat at least).  How easy would it be to switch to using 
epicsReadline instead on Linux?  We need to resolve this problem and 
either put libreadline as a requirement on Linux or make it easy to 
include or exclude within the build system.
