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

Tue Jul 7 16:14:37 UTC 2020

[UPDATE]: I tried building EPICS with RTEMS5 for pc-386 and pc-386-qemu.
Everything worked fine while building the pc-386 with  RTEMS5.

After this when I entered epics-base and made the following change:

epics-base/os/CONFIG_SITE.Common.RTEMS
RTEMS_VERSION = 5
RTEMS_BASE = /home/mritunjay/development/rtems_dev/$(RTEMS_VERSION)

As an experiment, I ran the make and as expected got the following error

Error:

```...de/compiler/gcc -I../../../../include/os/RTEMS -I../../../../include
        -c ../rtems_init.c
../rtems_init.c:21:10: fatal error: sys/termios.h: No such file or directory

```

I am trying to figure out the error and making the changes in code to debug
it.
However, I will appreciate if Heinz and everyone else can help me a little,
if they have an
idea of this error.

Thanks
Mritunjay
