[subhilash_4 at gracelabs.com]

hi, 

I followed the steps that mentioned in the link
https://github.com/RTEMS/rtems-libbsd [1] for sparc and 4.12 version 
# cd
/opt/
# mkdir RTEMS
# cd RTEMS

# sandbox="$PWD/sandbox"
# mkdir sandbox
#
cd "$sandbox"
# git clone git://git.rtems.org/rtems-source-builder.git
#
git clone git://git.rtems.org/rtems.git
# git clone
git://git.rtems.org/rtems-libbsd.git

Build and install the tools.
# cd
rtems-source-builder/rtems
# ../source-builder/sb-set-builder
--prefix="$sandbox/rtems-4.12" 4.12/rtems-sparc

Bootstrap the RTEMS
sources:
-----------------------------
# cd "$sandbox"
# cd rtems
#
PATH="$sandbox/rtems-4.12/bin:$PATH"
# ./bootstrap

# cd "$sandbox" or cd
..
# mkdir b-sis
# cd b-sis
# "$sandbox/rtems/configure"
--target=sparc-rtems4.12 --prefix="$sandbox/rtems-4.12"
--disable-networking --enable-tests=samples --enable-rtemsbsp=sis
# make
#
make install

Build and install
rtems-libbsd
================================

# cd "$sandbox"
# cd
rtems-libbsd
# git submodule init
# git submodule update rtems_waf
# waf
configure --prefix="$sandbox/rtems-4.12" --rtems-bsps=sparc/sis

this step
I got an error

Setting top to : /home/subhilash/RTEMS/sandbox/rtems-libbsd
