[Xenomai] Importance of missing modechk/cobolt.wrappers

[Per Oberg <pero@wolfram.com>]

Hello all


I'm working with a Yocto build of xenomai. I have compiled a sdk for building on a build-host but I am doing something wrong because I get the wrong path to modechk.wrappers and cobalt.wrappers. I could probably fix this but I just want to know whether this is a real problem or not. 

When I run xeno-config i get :
Xenomai: wrappers cannot be read from /usr/lib/modechk.wrappers
Xenomai: wrappers cannot be read from /usr/lib/cobalt.wrappers

The contents of the wrapper files are listed below for completeness. It seems like a lot of stuff that is not getting wrapped when these files are missing, and that would mean that I am missing a lot of wrapping and that I definitely need to fix it. Or is is just a warning? 

How do I know if the final software is wrapping stuff the way I want?
