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.

My host is linux-x86 and I would like to make

as my target architecture.

The R3.14 build system will compile everything for
the host machine automatically. You only need to set
CROSS_COMPILER_TARGET_ARCHS if you want it to cross-compile for a different target
(usually RTEMS or vxWorks) - leave it blank or commented out for just native
binaries.
