[libvirt PATCH] build: Make daemons depend on generated *_protocol.[ch]
Posted by Jiri Denemark 2 years ago 
This should fix build failures when a daemon code is compiled before the
included *_protocol.h headers are ready, such as:

Notes:
    I couldn't check this patch actually fixes the error because the build
    failure is non-deterministic and I cannot reproduce the failure now.

Thanks for taking this on! I planned to work on it next week when returning from 
medical leave. In the meantime I've only had time for the most urgent issues.

Although not urgent, giving this patch a spin in the openSUSE build service 
takes only a few minutes. And it looks good! The consistent ppc64le build 
failures no longer occur. I realize the patch is already pushed, but FTR

though I'm wondering if we have the same problem for the admin protocol
