Just for completeness and to confuse you....

The change Janet suggests will build HOST prods and libraries for

linux-xscale_be for all applications, everywhere.

(To avoid conflicts with version upgrades, it should rather be done in a

copy of that file, called .../configure/CONFIG_SITE.Common.linux-xscale_be.)

If you want this behavior only for one application, you could remove the

_HOST qualifier from the LIBRARY_HOST and PROD_HOST definitions in that

application's Makefiles, which will build only this application for HOST

and all IOC type architectures.

If you want only this application to build on the HOST and only one of

your IOC target architectures, you could leave the *_HOST definitions in

and add a similar *_IOC_linux-xscale_be definition to each one.

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?
