Ron,
For embedded Linux, I build and install the kernel, busybox etc
separately from EPICS.
For EPICS create an architecture based on linuxCommon with a unique name
and configure all the cross compiling tools. For example I have created
one for crisv10 for 4.14.8 (I think in 3.14.11 a cris configuration is
already included):
>cat CONFIG.Common.linux-crisv10
# Configuration for the cris cross compiler for
# crisv10 targets, e.g. axis ETRAX 100LX
# Include definitions common to all linux targets
include $(CONFIG)/os/CONFIG.Common.linuxCommon
VALID_BUILDS = Ioc
BUILD_CLASS = CROSS
CROSS = YES
GNU_DIR=/usr/local/cris
CMPLR_PREFIX=cris-axis-linux-gnu-
SHRLIB_LDFLAGS = -shared
LOADABLE_SHRLIB_LDFLAGS = -shared
/* this only works with a hack in ca/convert.cpp */
ARCH_DEP_CPPFLAGS += -DCA_LITTLE_ENDIAN
ARCH_DEP_LDFLAGS += -mcrislinux
COMMANDLINE_LIBRARY = EPICS
STRIP = $(GNU_BIN)/$(CMPLR_PREFIX)strip$(CMPLR_SUFFIX)
LINK.cpp += ; $(STRIP) $@

Best regards,
Dirk

I was wondering if anyone can suggest an approach for building EPICS
on multiple linux distributions (which may have different kernel
versions, compiler versions, etc.)
Does one define new architectures linux-x86-distribution_a
linux-x86-distribution_b?

And, what about Linux on embedded devices, such as VME CPUs? How are
people building kernels, drivers, EPICS, etc. and then deploying them to
production CPUs?
Are labs using standard Linux distributions for the likes of kernels,
drivers (and what about non-desktop oriented drivers, such as for VME),
and filesystems?
Has anyone composed a complete package of cross toolchains, root
filesystem, kernel + configuration, etc., that they use as any kind of
standard for embedded systems?
