Hey Michael,

as far as I understood, they would like to build everything (base,

support modules and IOC) just for the target arch.

But the error occurs for the IOC (which contains a custom support module)

The missing library is the libisegHal which is only build for linux-arm

as a part of the same yocto image.

The library is needed for iseg's support module.

Cheers,
Florian

Can you clarify a couple of points?

Are you referring to building EPICS Base itself, or a support module / IOC application?

Which libraries are missing?  (this might answer the previous question)

Hey all,

I was contacted by iseg with the following problem:

They want to include EPICS in their yocto image for the crate controllers.
The host system is a linux-x86_64 system, the target arch linux-arm.

Currently their Yocto recipe fails, because EPICS is build for both host and target arch and some libraries are missing for the host.

Is there a way to build EPICS only for a target architecture?

Best regards,
Florian
