Arch Linux

I am not familiar with the DD4hep tests or how to run them. I was also not able to reproduce your error. When I try to directly run thisroot.{csh,sh,fish} or even when I try to source it, it always gives me the following message "ERROR: thisroot.{csh,sh,fish} should never be user". Which to me is self-explanatory - do not use thisroot.{csh,sh,fish} to configure ROOT.

Apologies if I was not clear. The message is fine when directly sourcing thisroot.sh.

But create a file "test.sh" with these two lines:

source /usr/bin/thisroot.sh
echo "do something with root ..."

and then run "source test.sh" - You'll see something like:

k4-arch-01: ~$ source test.sh
basename: invalid option -- 'b'
Try 'basename --help' for more information.
ERROR: should never be used!
Connection to k4-arch-01 closed.

depending on how the script is called, basename may print all kinds of things, none of them self-explanatory. A very easy fix that might save others hours of debugging is to just explicitly print:

fail "ERROR: thisroot.{sh,sh,fish} should never be used!" 1

instead of dealing with all the ways that basename can fail.

For the second part of the issue, consider that many people may have written scripts that use thisroot.* with the arch installation it is not necessary, which is great, but using fail means breaking all those scripts. Why not print a warning and make sourcing thisroot.* a noop?

Would the attached script do the job?

That looks great, thank you very much!

this should ship in [community-testing]/root 6.24.06-5
