Thanks for the quick response Chris

It looks like I'm back in action.

No, it was  git://git.rtems.org/jennifer/examples-v2.git


I tried again with
git clone git://git.rtems.org/rtems-examples.git
cd rtems-examples
export RTEMS_MAKEFILE_PATH=/home/charles/quick-start/rtems/5/sparc-rtems5/erc32
make

That seems to have built properly.
I see there are also better READMEs.
