I have a project where I need to cross build some of the EPICS

extensions for another architecture.

Specifically, I want to build the ChannelArchiver to run on a remote

Linux host.

I already have the IOS compiled for the host (linux-xscale_be), and it

works well, with all the libraries and programs functional on that

architecture, but to make the machine I’m setting up an independent

system, I need to run the ChannelArchiver as well on that device.

I defined ‘CROSS_COMPILER_TARGET_ARCHS’ in the extensions configure

directory to ‘linux-xscale_be’, and when I build, I create a xscale_be

bin directory, however the build system doesn’t pick up the target build

tools, so it’s building 2 copies of the host programs.

What do I adjust to make the extensions build system pick up the proper

toolset?

You will need to create

base/configure/os/CONFIG_SITE.linux-x86.linux-xscale_be

In it, you can assign to '$GNU_DIR' the path to your cross tools. When

you do this, leave off any trailing 'bin' directory name, as EPICS build

will append this by itself. See the corresponding files for other

architectures as a guide.
