Re: Building EPICS base with Yocto

["Johnson, Andrew N. via Tech-talk" <tech-talk@aps.anl.gov>]

Hi Marcio,

I can’t help you specifically with Yocto or Bitbake, but for embedded IOC builds I would recommend turning off shared libraries for that target architecture and doing a static build of the IOC executable. You could even try whole-program-optimization if you know how.

That way you don’t have to worry about configuring shared library search paths since all the EPICS code will have been linked into the executable, and the IOC will probably start very slightly quicker as the OS doesn’t have to resolve all the internal symbols at load-time.

HTH,

Hello.

I’m familiar with the approach of building EPICS base in a host machine, selecting different architectures, and then configuring Yocto to access the EPICS libraries that are installed in the host. But was anyone able to build EPICS base using a Bitbake recipe inside Yocto?

Cheers,

Marcio
