Dear Experts,

I have problem with alibuild o2physics,when i execute order (alibuid build o2physics),it will report an error,reinstalling the system and deleting entire folders is not useful.

Here’s what’s wrong .

Building O2@nightly-20220712
==> O2 is being built (use --debug for full output): failed
ERROR: Error while executing /home/lh/alice/sw/SPECS/ubuntu2004_x86-64/O2/nightly-20220712-local1/build.sh on `lh-OptiPlex-7050’.

Your build fails because you have multiple ROOTs installed. The log file tells you that it sees some headers multiple times. Once here

a) /home/lh/llh/packages/root/

and then

b) inside alibuilds .../sw/.... folder.

You should delete a) and only work with the ALICE software stack. There is nothing wrong with alibuild.
