Yes, although as Jeff said you might need to add a few things to the
configure/os directory to get it to build. Since you're self-hosting I think
you should be able to use the generic target name linux-arm for this build,
which should simplify the Base configuration process.
You will need to create the file CONFIG.linux-arm.Common containing the line
include $(CONFIG)/os/CONFIG.UnixCommon.Common
but that might be all you actually have to do. CONFIG.Common.linux-arm may
look like it's only set up for cross-compilation, but those settings are
actually overrides to variables set in CONFIG.Common.UnixCommon so first try
building without making any changes there.
In case it's not clear, files names *.<host>.Common are included whenever
building on <host> irrespective of the target; files named *.Common.<target>
are included whenever compiling for <target> on any host; files named
*.<host>.<target> are used whenever that particular combination of <host> and
<target> are involved. Files named CONFIG.*.* contain default settings for
the build process, while files named CONFIG_SITE.*.* are intended for site-
specific settings such as paths that might vary (location of cross-compilers
etc.).
After a top-level 'make' succeeds, you will want to use 'make runtests' to
execute the build-in test programs (note that epicsMessageQueueTest takes 5
minutes to run, don't assume it has crashed when the messages stop mid-test).
Hope this gets you started, ask if you get stuck. I would be interested in
adding your configuration files to the Base distribution if you would like to
contribute them once you have everything working.
