[Mritunjay Sharma]

[UPDATE]: The error was actually a mismatch of names which was fixed with
the following
changes:

------------------------------

After this, I ran the command

`../source-builder/sb-builder --prefix=/home/mritunjay/development
--log=log_epics epics-7-1 --trace`

again. The error that has come now was expected because the changes I
made in epicsBaseOwnPlayground/configure file

were done manually and here it has to be done through a script. The
changes that I did manually were;

in epics-base/configure/CONFIG_SITE

   What I entered:
   CROSS_COMPILER_TARGET_ARCHS=  RTEMS-pc386-qemu

Checked.  CONFIG.Common.RTEMS-pc386 was there

In my system, I entered this:
#FHI
RTEMS_VERSION = 5
RTEMS_BASE = /home/mritunjay/development/rtems/$(RTEMS_VERSION)

I have a doubt on how to implement the above changes in the
`source-builder/config/epics-7-1.cfg` to make it work.

Do we have to write a patch? And what will be the best way to do it?

The latest error looks somewhat like this which is because I have to
change the configurations in epics directory.

The question is how to accomplish it through the script.

../../configure/os/CONFIG.Common.RTEMS:36:
/Users/junkes/MVME6100/RTEMS/rtems-5/powerpc-rtems5/beatnik/Makefile.inc:
No such file or directory



Thanks
