Re: EPICS Soft IOC question

[Bruce Hill <bhill@slac.stanford.edu>]

Hi Andrew,
One thing that tends to be different for an EPICS software site is that
each IOC typically has it's own release cycle.   Any organization or top
down makefile support for your IOC's is purely for your benefit.
Thus, there are probably nearly as many ways of organizing them as there
are EPICS sites.

The other point to consider is whether or not you intend to make your
own updates or additions to the EPICS base or any of the available
EPICS modules.    To build your IOC, you need have a directory
structure that organizes the various versions of base and modules that
your IOC needs.    If you're also going to make your own versions of
base and/or modules, you'll want those in version control as well.

Here's the way my group organizes them, FWIW.
$(RELEASES)/epics/base/<version>
$(RELEASES)/epics/modules/<module_name>/<version>
$(RELEASES)/epics/ioc/<hutch>/<ioc_name>/<version>
$(RELEASES)/epics/screens/edm/<hutch>/<version>

In svn, it looks like this:
~/svn_wa/epics/base/current
~/svn_wa/epics/modules/<module_name>/current
~/svn_wa/epics/ioc/<hutch>/<ioc_name>/current
~/svn_wa/epics/screens/edm/<hutch>/current

HTH,

Try this... and see what comes out!
${EPICS_BASE}/bin/${EPICS_HOST_ARCH}/makeBaseApp.pl -t example base
${EPICS_BASE}/bin/${EPICS_HOST_ARCH}/makeBaseApp.pl -i -t example -a ${TARGET_ARCH} base

I have my own directory structure in my SVN tree.
I built my own makefiles.
No sure you want to do that for only a few IOCs.
The directory structure I have is as follow
.../svn/<synchrotronId>/drivers/<driverName>/{db|doc|medm|qt|msi|iocBoot|dbd|medm|stream|src|...}/
.../svn/<synchrotronId>/iocs/<iocName>/{db|doc|medm|iocBoot|dbd|msi|medm|qt|src|...}/
.../svn/<synchrotronId>/opis/<opiSoftware>/{bin|etc|...}/
The Makefiles build, configure, and install the software based on hostname, arch, etc...
So yes, you can make it as complicated as you want ;-)

Good luck,

Hi,

I have downloaded the EPICS IOC core on a redhat machine. I need to run
atleast 3-4 soft IOc on this machine, but i am not able to decide on the
directory structure. i do not want it to be complicated. Can anyone help me
with a directory structure for the database, drivers etc ?

Thanks,

Andrew
