Hi Vijay,

my colleagues have seen similiar issues with the unresolved SHELL commands:

I have tried these commits out with both legacy stack and libbsd
stack, I'm getting similar link errors with them:
```

```
This has something to do with the makefiles in EPICS. I would like to
take a deeper look if it has not been solved already. Do you have any
hints about where in the makefiles should I be looking?

Best regards,
Vijay

Hello Vijay,
thank you for taking care of this. I had unfortunately neglected to mention that we currently have a PR specifically for RTEMS to support RTEMS5/6 in the future.
I also want to address these things next week at the codeathlon and hope that we can bring it to a secessful conclusion there.
I have created documents in OpenProject (I'll send you an invitation to it in a moment) for installing RTEMS5/6 and EPICS there: https://op.fhi.mpg.de/projects/epics-codeathon-rtems/documents
I just redid the whole thing and it looks much better for RTEMS6 (I don't know what I did wrong yesterday).
It looks to me like there are just a few settings missing in the net-extra-lib-legacy ;-)

I can unfortunately only this evening look further what is still missing ...
Heinz

Hello Heinz,
I am starting this offlist thread to work together on the failing

If I could build it with RTEMS 6 without libnetworking, then I will be
able to investigate what is crashing the build.

Vijay
