Title: Cross Building Extensions

R3.14.11 base contain a configure/CONFIG.Common.linux-xscale_be file.  It is set up to build only IOC prods and libraries.
Comment out the line "VALID_BUILDS = Ioc" to build both HOST and IOC prods and libraries.

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?
