RootBuild

From Chris Green 10/2019. Assuming you wish to build a ROOT UPS product in a temporary place and then install it elsewhere:

1. Ensure the relevant product stack is installed and accessible via PRODUCTS.
2. Make a temporary products area:
mkdir product-tmp cd product-tmp
3. Initialize it from an existing UPS area:
tar -C ${PRODUCTS%%:*} -c .upsfiles | tar xv
4. Obtain the correct source tarball:
curl -O -J -L --fail https://scisoft.fnal.gov/scisoft/packages/root/v6_16_00/root-6.16.00-source.tar.bz2 | \ tar xj
5. ...and build:
./root/v6_16_00/build_root.sh e17 debug tar
6. Unwind the tarball in the location from which you wish to use it (removing the existing build first if necessary) and then remove product-tmp.

Building in a temporary area and then installing the tarball will take care of removing intermediate build products which are not part of the final build (object files, etc., etc.).
