Hi all,

Currently, I do some contractor work for Gemini for a new Application

Development Environment based on RPM.

In this context, I am working on one part of it to provide a framwork

for softIOC installation, everything readily set up with conserver

configuration, procServ etc. after installing a respective softIOC RPM.

I do this development work based on a makeBaseApp.pl generated softIOC

example from the EPICS Application Developer's Guide (

https://epics.anl.gov/base/R3-15/6-docs/AppDevGuide/GettingStarted.html#x3-60002.2

). For installing EPICS software using RPM we have to _relocate_

installed binaries, scripts etc. This works well, principally, but

regarding the example softIOC there do arise a few questions:

(1) The startup file under iocBoot (st.cmd) is not installed anywhere.

If INSTALL_LOCATION is not redefined, then this is not a problem, but if

I want to keep the sources distinct from the product, this seems not to

be consequent. I patched the Makefile from

TOP = ../..
include $(TOP)/configure/CONFIG
ARCH = $(EPICS_HOST_ARCH)
TARGETS = envPaths
include $(TOP)/configure/RULES.ioc

to

TOP = ../..
include $(TOP)/configure/CONFIG
ARCH = $(EPICS_HOST_ARCH)
TARGETS = envPaths
SCRIPTS_IOC_Linux += st.cmd
include $(TOP)/configure/RULES.ioc
include $(TOP)/configure/RULES

to install the st.cmd to the binary install dir, at least. In the %post

section of the RPM specfile (which is called after installing an RPM) I

could then call convertRelease.pl again to let envPaths look like it

should. Is this the way to go? Or is there a better way (I believe I

remember sth like directories named 'startup' or so in the past, but

maybe this was Gemini-specific)

(2) Another option I thought about would be to define a User Created

File type

(

https://epics.anl.gov/base/R3-15/6-docs/AppDevGuide/BuildFacility.html#x5-1570004.6.35

), e.g. a FILE_TYPE IOCBOOT which would install this st.cmd to a

INSTALL_IOCBOOT = $(INSTALL_LOCATION)/iocBoot/.... directory, for example.

Or do I think completely in the wrong direction and there is already a

mechanism in place which I simply do not see?

Any help or ideas appreciated.

Thanks,
Felix
