Updating LArsoft version whilst keeping the old compilation¶
This is useful for when you want concurrent prof/debug builds using the same source code or you want to update your LArsoft version. You can keep you old build with the version of LArsoft you were running and test if updating causes some error to appear. From a new shell setup the LArsoft version you want e.g. if you wanted v06_59_00:
setup larsoft v06_59_00 -q e14:prof cd v06_59_00.prof mrb newDev -T v06_59_00.prof -f
-T tells mrb what directory to put the localproducts and build directory in.
-f tells mrb to use the src directory that already exists.
