[GSoC 2020: Daily Update]: Building EPICS with RTEMS5

[Mritunjay Sharma]

[UPDATE]: After using --enable-posix, the 'make' in epics-base worked
successfully.
With all of yours support, there are no errors. Everything seems to be
in order.

Heinz, as you suggested, now I have built EPICS with RTEMS 4.10 for pc-386
and as advised that after this
we can take care of RTEMS5 (or 6?) and libbsd as I have learnt now how to
build EPICS and I think we can develop
a first rsb-set for it.

Please advise on what to begin with next.

Thanks
Mritunjay
