In the past you had to build the EPICS_HOST_ARCH because there were host tools built at the beginning that were needed later on in the build. I don't know if that is still the case with the more recent version of EPICS base.
What EPICS base version are you trying to build without the host architecture?

Thanks for your quick reply, Kevin.

However what I´m looking for is to compile only for a target_architecture and not for the host. For example Host: x86_64 Target: Linux-arm. I just want to compile for linux-arm from my x86 host.

Ricardo,

If you leave CROSS_COMPILER_TARGET_ARCHS empty in the
configure/CONFIG_SITE of the module you're building, it should only
build for the host arch:

  CROSS_COMPILER_TARGET_ARCHS =

Hello,

 I want to ask you how to compile only for one target architecture in
EPICS. In the application developer´s guide it is not clear enough . It
seems as it always compile for host and for other target architectures.
I want to compile for one target architecture, but not all of them and
not for the host architecture. I just need to compile for linux-arm in
any case from a x86_64.  How can I do that?

Thanks for your help, in case you need it I can send you the Makefiles I
´m working on.
Ricardo
