RE: EDM wants to build on vxWorks-68040 target. Why?

["Singleton, SJ \(Steve\)" <steve.singleton@diamond.ac.uk>]

Hello Mark et al,

This problem seems to have come about as a result of a change to the EDM
build round about version 1.10.1ze; prior to that it used 3.13 style
make files and built only on the client platform.

If you have a shared EPICS base that is used by a number of developers
to build things for vxWorks IOCs as well as client applications,
changing BUILD_ARCHS in base/configure/CONFIG_COMMON is not a practical
solution, as the change affects everyone.   I came up with a solution
that doesn't affect programs other than EDM (though it involves rather
more effort).  In the MAKEFILEs in all of the subdirectories of
extensions/src/edm, replace any

PROD=

definitions with equivalent

PROD_HOST=

Definitions, and any 

LIBRARY=

definitions with equivalent

LIBRARY_HOST=

Definitions.  Then edm is built for host architectures only.

Regards
Steve Singleton

There was no Makefile.Vx in my source directory.

I followed the maze of Makefile includes to the culprit. In

${MY_EPICS_BASE}/configure/CONFIG_COMMON

there is

BUILD_ARCHS = $(EPICS_HOST_ARCH) $(CROSS1) $(CROSS2)

Changing that to

BUILD_ARCHS = $(EPICS_HOST_ARCH)

fixed the problem. (I then changed it back after compiling edm.)

I'm an EPICS newbie so I'm looking for a bit of enlightenment with these
questions:

Why would edm, or any other extension, use BUILD_ARCHS, when they will
run on the EPICS_HOST_ARCH only?

How can I tell edm, without touching stuff in ${MY_EPICS_BASE}, that it
shouldn't build for the target(s), only the host? I tried mucking with
stuff in ${EPICS_EXTENSIONS}/configure and ${EPICS_EXTENSIONS}/src/edm
to no avail.

Is there an extension that is a shining example of the proper use of
the EPICS 3.14 build system?
