Yes, I will make surely make sure of it.

Hi Chris,

I tried to debug this with the help of trace file and what you suggested
above. I still haven't been successful in it.
With RSB 5 branch when sb-builder was available, the EPICS build was
running successfully using RSB recipe. However, in the RSB master,
sb-builder is no longer available and I used sb-set-builder to build EPICS.
I used this command:

`../source-builder/sb-set-builder --with-rtems-bsp="xilinx_zynq_a9_qemu"
--log=log_epics epics/epics-base  --trace
--prefix=$HOME/development/rtems/5-arm
--with-tools=$HOME/development/rtems/5-arm --host=arm-rtems5
`

This gave me the following error again and again
cleaning: epics-base-7.0-arm-rtems5-1
error: copying tree (4):
/home/mritunjay/development/rtems/src/rsb/rtems/build/tmp/epics-base-7.0-arm-rtems5-1-1000

For your reference, Below is the last part of the log file. Please see if
you can help me out and tell me if you want me to share any other details

I am not sure what 'install pass' means but if it has something to do with
make, then only `make` was used which
is the same thing done when building by hand.

Thanks
